which youll be riding, and with feet shoulder(pedal) width apart. If the top of your inseam(crotch) touches the frame, the bike is too bigfor you.

4.1.2 Saddle PositionSaddle height and position are extremelyimportant factors in determining your comfortand performance. Due to Lafrees uniquehinged saddle, fore/aft saddle position is fixed.However, the most important aspect of saddleposition - saddle height - can and should beadjusted for maximum comfort and pedallingefficiency.

4.1.2.1 Height AdjustmentPut your heel on the pedal at its lowestposition. Your leg should be stretched with aslight bend in the knee. Use this as a rule ofthumb. If you do not feel comfortable, slightadjustments may be necessary.

To adjust the saddle height: Loosen the seatbinder quick-release cam lever (Fig. 4B; seealso Section 7.8 on Seat Post Quick-Re-leases) and move the seat post up or down asrequired. Re-tighten the seat binder, securingit so that the post does not twist. Check theadjustment as described above. Under nocircumstances should the seat post protrudefrom the frame beyond its Minimum Insertionor Maximum Extension mark (Fig. 4C).

4BIKE SIZING AND SAFETY

FIGURE 4B

4.1 Size

WARNING: A bike that is too big or toosmall for the rider can be difficult tocontrol and can be uncomfortable. Ifyour bicycle does not fit properly, youmay lose control and fall.

4.1.1 Frame sizeLafrees sloping primary frame tube allowsfor greater standover clearance for a widevariety of riders (clearance between primaryframe tube and top of inseam while straddlingthe bike just in front of the saddle). Yourdealer will have made sure you had thecorrect standover clearance, based onphysical examination. If someone elseselected a Lafree for you, as a gift, forexample, it is important to have the correctstandover clearance before attempting to rideit (Fig. 4A). If you cannot stand flat-footed withfeet at shoulder width without coming intocontact with the primary frame tube, westrongly suggest that you do not attempt toride Lafree.

To check for safe standover height, straddlethe bike while wearing the kind of shoes in

FIGURE 4A


WARNING: If the seat post protrudesfrom the frame beyond the MinimumInsertion or Maximum Extension mark(see Fig. 4C) the seat post may break,which could cause you to lose controland fall. Riding Lafree with the seatpost protruding from the frame beyondthe Minimum Insertion or Maximum Extension mark can also damage theframe.

WARNING: After any saddleadjustment, be sure to tighten thesaddle adjusting mechanism properlybefore riding. A loose seat post bindercan cause damage to the seat post, orcan cause you to lose control and fall. Periodically check to make sure thatthe saddle adjusting mechanism isproperly tightened.

4.1.3 Handlebar Height and Angle

4.1.3.1 Handlebar positionThe position of the handlebar is important forcomfortable cycling. When adjusting handlebar position, refer to torque setting table atsection 8.2.

WARNING: The stems MinimumInsertion Mark must not be visibleabove the top of the headset (see Fig.4D). If the stem is extended beyond theMinimum Insertion Mark the stem maydamage the forks steerer tube orbreak, which could cause you to losecontrol and fall.

Handlebar position can be adjusted as follows

4.1.3.2 Handlebar stem heightThere is no general rule for the height of thehandle bar. For a more sportive ridingposition, choose a lower position. For a morerecreational riding position choose a higherposition. To adjust the handlebar height:loosen the stem binder bolt (Fig 4D) three orfour turns. Tap the bolt carefully down, using aplastic or wooden hammer. Set the handlebarstem at the correct height and perpendicularto the front wheel. Fasten the bolt to thecorrect torque.

4.1.3.3 Handle bar angleBy tilting the handle bar you can direct thegrips more upward or downward. This is amatter of personal taste. Loosen the bolt atthe front side of the handle bar stem. Tilt thehandle bar to the required position. Fasten thebolt to the correct torque. Check and ifrequired adjust the position of the brakelevers.

4.1.3.4 Handle bar stem angleSome models are equipped with an adjustablehandle bar stem. This allows you to adjust theangle of the handle bar stem extension.Loosen the inclination bolt and set theextension to the required inclination. Fastenthe bolt to the correct torque. Check and ifneeded adjust the position of the brake levers.

4.2 Safety Equipment

WARNING: Many countries requirespecific safety devices. It is yourresponsibility to familiarise yourselfwith the laws where you ride and tocomply with all applicable regulations,including properly equipping yourselfand your bike as the law requires.

4.2.1 ReflectorsReflectors are important safety devices whichare designed as an integral part of Lafree.The reflectors are designed to pick up andreflect street lights and car lights in a way thathelps you to be seen and recognised as amoving bicyclist.

CAUTION: Check reflectors regularly to makesure that they are clean, straight, unbrokenand securely mounted. Have your dealerreplace damaged reflectors and straighten ortighten any that are bent or loose.

4.2.2 LightsIf you ride your bike after dusk, your bicyclemust be equipped with lights so that you cansee the road and avoid road hazards; and sothat others can see you. Vehicle laws treatbicycles like any other vehicle, which meansan illuminated white front, and a red rear light,not just reflectors, if you are riding after dusk.A properly fitting lighting system is beingoffered as a Lafree optional accessory. Please ask your dealer.

4.3 Mechanical Safety ChecksLafree is equipped with several unique safetyfeatures, described in more detail in section 7.

Speed Actuated Motor Shut-Off-Automatically disengages motor whenLafree reaches 25 km/h.

Brake Actuated Motor Shut-Off-Automatically disengages motor when oneor both brakes are applied.

Automatic Key Lock-Locks Energy Set intoplace when ignition is at ON position.

Self Diagnostic Sequence-Automaticallychecks that VPC Throttle, Brake ActuatedMotor Shut-off, and the torque sensor arefunctioning.

Safety switch disables the motor-electricassist simply by flipping the handlebarmounted switch to the off position.

Please be sure to familiarise yourself withthese features before operating Lafree. Hereis a simple, sixty-second mechanical safetycheck which you should get in the habit ofmaking every time youre about to get onLafree.

4.3.1 Diagnostic ReadoutLafree is equipped with a five-point diagnosticcheck of the electronic features:

front and rear brake motor cut-off function VPC Throttle function torque sensor function speed sensor function

To initiate diagnostic sequence, turn ignition toON position and push Self-Diagnostic button.

4.3.2 Nuts & boltsInspect the bike closely from front to rear forany obvious signs of worn or brokencomponents. Grasp the handlebar with bothhands and lift the front wheel off the groundabout 5-10 centimetres, then let it drop firmlyon the ground while still holding thehandlebar. If anything sounds, feels or looksloose, do a quick visual and tactile inspectionof the whole bike. Try to find the source ofnoise or any obvious loose components, andsecure them. If youre not sure, ask someonewith experience to check, or take your Lafreeto your authorised service centre.

4.3.3 Tyres & WheelsCheck proper tyre inflation by placing yourhand directly on top of each individual tyre.With a straight arm and direct downwardpressure, push on the tyre with downwardbody weight and watch the spot where thetyre is contacting the ground. There should bevery little tyre compression. If your tyres need

10


inflating, use a standard bicycle floor pump. Ifyou must use a high-volume compressor likethose found at automotive service stations,add air in small amounts as thesecompressors are designed to fill auto tyreswhich have much larger volumes than bicycletyres. A surge of pressure could cause theinnertube to explode, which can cause severedamage to the tyre and serious injury.

Spin each wheel slowly and look for cuts inthe tyres tread and sidewall. Replacedamaged tyres before riding the bike.

Spin each wheel and check for brakeclearance and side-to-side wobble of the rim. Ifa wheel wobbles side to side or contacts thebrake shoes (front brake only), take the bike toa qualified dealer to have the wheel aligned.

CAUTION: Wheels must be true (aligned)for the brakes to work effectively. Wheel truingis a skill which requires special tools andexperience. Do not attempt to true a wheelunless you have the knowledge and toolsneeded to do the job correctly.

4.3.4 BrakesLafree offers models with rim brakes (Fig 4E,4F) and with disc brakes. Visually inspect forproper cable routing.

Squeeze the brake levers. Brake leversshould engage hoes/rear roller brake atapproximately half way through their arc, orwithin about 2,5 centimetres of handlebar grip.To check proper brake lever travel, encirclethe hand grip with your thumb and forefinger,then squeeze the brake lever with theremaining three fingers of each hand. If youcan squeeze the levers so that they touchyour forefinger, you should have a qualifiedservice centre adjust your brakes.

Make sure that the front brakes brake shoesare contacting the rims braking surface fully(Fig. 4H). Also check that the shoes are notcoming into contact with the tyres sidewallwhilst applying the brake. Riding the bike withbrake shoes contacting the sidewall cancause the tyre to be damaged and theinnertube to puncture, which may cause youto lose control and fall. Do not ride the bikeuntil the brakes are properly adjusted. SeeSection 7.9 for details.

WARNING: Riding with improperlyadjusted brakes or worn brake shoes isdangerous and can result in seriousinjury.

Please see the attached owners manual forinformation on disc brakes.

FIGURE 4E

FIGURE 4F


4.3.5 Quick-ReleasesCheck to see that the front and rear wheeland seat post quick-release levers areproperly adjusted and in the CLOSE position.See Section 7.7+ 7.8 for details.

WARNING: Riding with an improperlyadjusted wheel quick-release cancause the wheel to wobble ordisengage from the bicycle, which cancause damage to the bicycle or seriousinjury.

4.3.6 Handlebar and saddle alignmentAre the saddle and handlebar stem correctlyin line with the bikes top tube and tightenough so that you cant twist them out ofalignment?

4.3.7 Handlebar endsAre the handlebar grips secure and in goodcondition? If not, replace them. Are thehandlebar ends plugged? If not, plug thembefore you ride.

You are now ready to safely ride your Lafree.However, we suggest that you take a fewmoments to review the following chapters onriding tips and safety, especially if you havenot ridden a bicycle in a long time.

NOTE: Riding a bicycle involves certain risks,including damage and injury. By choosing toride a bicycle, you assume personalresponsibility for those risks. The people whosold you the bike, the manufacturer, thedistributor, and people who manage ormaintain the roads and trails you ride on arenot responsible for your actions. Therefore, itis extremely important that you understand-and practice-the rules of safe and responsibleriding, and to use common sense wheneverpossible and applicable.

5.1. The BasicCarry out the Mechanical Safety Check(Section 4.3) before you attempt to rideLafree, In addition, make sure that you alwaysfollow the electronic diagnostic procedure forLafrees power assist features.

5.2. Rules of the Road1. Learn the local bicycle laws andregulations. Many countries have specialregulations about licensing of bicycles, ridingon sidewalks, laws regulating bike path andtrail use, and so on. Many countries havehelmet laws, child carrier laws and specialbicycle traffic laws. In most countries, abicyclist is required to obey the same trafficlaws as the driver of a car or motorcycle. It isyour responsibility to know and obey the laws.

2. Some Lafree models are equipped with afront suspension (suspension fork). Whenbraking, the front suspension compresses andthe front end may drop noticeably. You couldlose control and fall if your riding skills are notsufficient to negotiate this mechanical functionof the suspension fork. Familiarise yourselfwith your suspension by practising braking ina safe area on flat ground before riding athigher speeds over varied road surfaces.

5.3 Wet Weather RidingUnder wet conditions, the stopping power ofyour brakes (as well as the brakes of other

vehicles sharing the road) is dramaticallyreduced, and tyre-to-surface adhesion(traction) is also compromised. This makes itharder to control speed and easier to losecontrol. Whenever wet conditions are present,reduce speed and apply your brakes earlierand more gradually than you would undernormal, dry conditions.

5.4 Night RidingRiding a bicycle at night is much moredangerous than riding during the day.

WARNING: Riding at dusk, after dark orat times of poor visibility without abicycle lighting system which meetsnational laws and without reflectors isdangerous and can result in accidents.

Before riding at dusk or at night, take thefollowing steps to make yourself more visible:

Make sure that your bicycle is equippedwith correctly positioned and securelymounted reflectors (see Section 4.2.1,Reflectors).

Make sure that lights and reflectors are notobstructed by your clothing, accessories, oranything you may be carrying on thebicycle.

Do not place Energy Set into a fire or nearintense heat source as it can explode andcause serious injury.

When cleaning the Energy Set casing, usea cloth moistened with water only. Do notuse solvents or cleaning solutions of anykind.

Do not attempt to open Energy Sets batterycase or charging unit. There are no user-serviceable parts in the Energy Set. If yoususpect a problem, take Lafree and EnergySet to your authorised Lafree dealer.

Inspect the Energy Set periodically forcracks, unusual residue, or other abnormalappearance. Do not operate Energy Setwith cracks or breaks in the casing.

Do not attempt to use Energy Set as apower supply for anything other than Lafree.

Always pull gently on the charging cord.Never yank or extend past its full length. Toremove from power outlet, pull on the plug,not on the cord.

6.4 Radius of actionThe radius of action is the distance you cancycle using the power assistance. The Lafreeradius of action depends on two factors:

the battery capacity

the cycling circumstances and maintenanceof the bicycle

Under the best possible circumstances, youcan cycle approx. 30-40 km using the powerassistance system. However, the followingfactors can influence the radius of action ofyour Lafree:

the temperature

the wind

the weight of the rider and loading

the number of stops and starts

the terrain (flat, steep hills or slopes,pavement)

the quality of tyres and chain

It is extremely important to the performance,enjoyment and safety of Lafree and yourselfto understand how many of the features ofLafree operate. You should not assume thatthe way things have worked on previouslyowned bicycles operate similarly on Lafree,even if youre an experienced bicyclist. Besure to read - and to understand - this sectionof the owners manual. If you have even theslightest doubt about how any of themechanical features of Lafree operate, talk toyour authorised Lafree dealer.

7.1 Variable Power Control(VPC Throttle)

Lafrees Variable Power Control (VPC) Throttlegives you instant access to the motors powerfor going up hill or into a headwind, or if yousimply dont want to use any of your ownpower! You control the amount of power outputsimply by twisting the right VPC Throttle.Twisting the VPC Throttle in acounterclockwise direction against the gripsspring tension (rearward) applies power fromthe electric motor, while releasing the grip in aclockwise direction (forward) decreases powerfrom the electric motor (fig. 7A).

The ignition-lockset and safety switch must be

ON. Lafree requires pedal input for motoroutput. This means that under any pedalexertion, Lafree will respond with electricalassistance. You can control the amount ofpower output simply by twisting the VPCThrottle, which is located on the right side ofthe handlebars.

When your speed reaches or exceeds 25 km/h,Lafrees motor will automatically disengage andstop assisting until the speed drops below 25km/h. You must pedal to enable the motor toengage VPC Throttle. If you stop pedallingwhile VPC Throttle is in the ON (twistedcounterclockwise) position, motor assist willcease until pedals begin turning again. Thethrottle must also be twisted completelyclockwise (no power) then twisted counterclockwise again for VPC Throttle to engage.

For safety, do not pedal Lafree while the bikeis leaned over in a turn and VPC Throttleengaged, as the pedal may come in contactwith the ground or other elevated obstacle. Itis best to put the pedals parallel to the groundat nine and three oclock, or with the insidepedal (side the bike is leaning toward) at 12oclock and the outside pedal at six oclock.

WARNING: For safety, do not pedalLafree while the bike is leaned over ina turn and VPC Throttle engaged, asthe pedal may come in contact with theground or other obstacles and causeyou to lose control and fall.

CAUTION: Using VPC Throttle exclusivelydrains energy more quickly. Use VPC Throttlesparingly for optimum energy range andconsumption.

7.2 Power Assisted PedalLafrees power assisted pedal system utilisesa fuzzy logic CPU (central process unit) toprovide constantly monitored powerassistance based on speed and pedal force.

7HOW THINGS WORK

FIGURE 7A


19

To engage power assisted pedal, turn ignitionswitch to the on position (please read Section6.2.1, Charging the Energy Set, beforeoperating Lafrees electric functions). Beginpedalling as with a traditional bicycle. Powerassisted pedal will automatically engage. Besure to sit down on the bicycle first with bothhands placed on the handle before ridingaway. Other ways of getting on and ridingaway could lead to dangerous situations.

To attain higher or lower speeds, shift the rearderailleur into the smaller or larger cogs asdescribed in Section 7.10, Shifting The Gears.

When your speed reaches or exceeds 25km/h, Lafrees motor will automaticallydisengage and stop assisting until the speeddrops below 25 km/h. You must pedal toenable the motor to engage power assistedpedal.

7.3 Energy Set IgnitionFor the functioning of power assistance and thediagnostic features, the energy set ignitionmust be switched to the ON position. Pleaseread Section 6, Charging the Energy Setbefore operating Lafrees electric poweredfunctions.

7.3.1 The ignition switchYour Lafree comes standard with two ignitionkeys to operate the ignition switch. Lafreesignition switch has three positions; OPEN, ONand OFF (fig. 7B):

OPEN-Lafrees electronic features will notfunction. The Energy Set can only beremoved when the ignition is in the OPENposition.

ON-The Energy Set provides power to themotor and electric features. The Energy Setis automatically locked into the Energy Setcompartment when ignition is in the ONposition.

OFF-Lafrees electronic features will notfunction. The Energy Set is locked into theEnergy Set compartment and the key canbe removed. (Use this feature for maximumsecurity.)

7.3.2 The safety switchA remote ON/OFF switch, mounted to thehandlebars, is integrated into the ignitionsystem. This is called the safety switch. Thesafety switch must be turned to the ONposition before electric assistance can beprovided form Lafrees motor. The switch canalso be used to momentarily turn the Lafreeselectric assistance off during use.

Start Lafree by turning the key to the ONposition. Following this, turn the safety switchto the ON position. You should hear anaudible Beep. The amount of stored energywill then appear as 1-5 lights on the energyindicator located on the top front of the motorhousing. Five lights on the indicator representthat Lafrees Energy Set is fully charged.

CAUTION: When leaving Lafree unattended,turn ignition to OFF position and remove key.Leaving ignition in the ON position whileparked will result in more rapid energy loss,and the potential for theft.

7.4 Self-Diagnostic CheckLafree is equipped with an on-board five-pointself diagnostic-check of the electronicfeatures:

front and rear brake-actuated motor shut-offfunction (audible beep sound)

speed sensor function (audible beep sound) VPC Throttle function torque sensor function

To initiate self-diagnostic mode, engageLafrees support stand in its down position.Turn ignition to ON position (there will be ashort beep). The Lafree keys are equipped

FIGURE 7B


20

with a pin to activate the self-diagnostic check.Push and hold Self-Diagnostic switch, thesmall black rubberised button located to theleft of the LED string/energy indicator (Fig.7C). Release pressure on the button afterhearing a long beep, indicating Self-Diagnosticcheck is ready to be performed. To performdiagnostic check, follow the directions below:

Brake Actuated Motor Shut-Off-Pull on eachbrake lever individually. If functioning, abeep will occur each time the lever is pulled.

Speed sensor: With the support stand in thedown position, lean the bike over slightly untilthe rear tyre comes off the ground. Pedal thecrank arm to get the rear wheel turning. Ifspeed sensor is functioning, an audible beepwill sound repeatedly as the magnetics onthe magnetic pie plate are detected by thesensors until the wheel stops. Stop the rearwheel with the rear brake. Do not place thetyre back in contact with the ground while therear wheel is moving.

VPC Throttle: Rotate the right-hand twistgrip. The VPC-throttle functions properly if allLEDs light up from 1 to 5, depending on howfar the VPC-throttle is turned up. Should oneLED be skipped or fail to light up completely,your dealer needs to be contacted.

Torque sensor: Place Lafree on its supportstand. With one hand, put light pressure oneither pedal while holding the rear tyre withthe other hand and rotate the crank arm

forward until an audible beep is heard.Some or all of the LEDs may illuminatedepending on how much pressure (torque)is being applied.

CAUTION: If any of these features fail thediagnostic check, take your Lafree to anauthorised Lafree dealer immediately.Operating Lafree with the Energy Set on, butwith any or all of these features inoperablecould cause severe damage to the electroniccircuitry and could cause you to lose controland fall.

To a) cancel Self-Diagnostic mode, b) re-setSelf-Diagnostic mode, c) to turn on Lafreespower assist features after using the Self-Diagnostic mode - turn the ignition or thesafety switch to the OFF position, then back tothe ON position.

WARNING: Never ride Lafree in theSelf-Diagnostic mode as it could causesevere damage to the electroniccircuitry. Lafrees power assisted pedaland VPC Throttle will not work while inthe Self-Diagnostic mode.

7.5 Light Emitting Diode (LED)Energy Level Indicator

Available energy is indicated via a LightEmitting Diode (LED) string, located on thetop front of the motor housing. When fullycharged, all five LEDs will be illuminated.

LEDs will only illuminate when ignition is on.As energy is used, fewer LEDs areilluminated. When only one lit LED remains,energy level is one percent. If energy leveldrops below one percent, motor willautomatically shut down and one LED willflash. If motor shuts off and single LED beginsflashing, turn ignition to OFF. Do not operateelectric functions until at least a 40 percentcharge (three LEDs illuminated) has beenattained. Charge time for this level isdepending on age of battery and how manytimes battery has been charged/discharged.See Section 6 for more information on batterycharging times.

adjusting nut, by way of the skewer, againstthe other dropout. The amount of clampingforce is controlled by the tension adjustingnut. Turning the tension adjusting nutclockwise while keeping the cam lever fromrotating increases clamping force; turning itcounterclockwise while keeping the cam leverfrom rotating reduces clamping force. Lessthan half a turn of the tension adjusting nutcan make the difference between safeclamping force and unsafe clamping force.

NOTE: Once the quick-release is installed inthe hub axle by the manufacturer or thedealer, it never needs to be removed unlessthe hub itself requires servicing. If the hubrequires servicing, consult your dealer.

7.7.2 Front Wheel SecondaryRetention Devices

Lafree is equipped with a secondary wheelretention device to keep the wheel fromdisengaging if the quick-release is incorrectlyadjusted or the cam opens accidentally.Secondary retention devices are not asubstitute for correct quick-release adjustment.

Lafrees secondary retention device is integralwith the fork dropouts and is recessed for thequick-release lever that keeps the wheel fromdropping out of the forks dropouts should thequick-release lever open accidentally.However, these tabs are not designed to keepthe wheel in place should the quick-releaselever open accidentally. If you hear or feellooseness coming from the front wheel, stopriding immediately and check the quick-releasetension. Ask your dealer to explain Lafreessecondary retention device in more detail.

WARNING: Removing or disabling thesecondary retention device is extremelydangerous and may lead to seriousinjury. It also may void the warranty.

WARNING: do not lean Lafree over onits side when removing the front wheel,as damage will occur to the lead acidbattery. The only time Lafrees frontwheel should be removed is torepair/replace a punctured innertube.

Some models are equipped with axle nuts.For removing the front wheel, loosen the nutand follow the procedure. For installing thefront wheel, refer to the torque setting tablewhen fixing the nuts.

7.7.3 Removing Quick-Release FrontWheel

(a) Place Lafrees support stand in its downand locked position.

(b) Release the front brakes elbow cableguide and spread the brake shoes toallow the front tyre to move in betweenthem (Fig. 7E).

(c) Rotate the wheels quick-release leverfrom the locked or CLOSE position (youcan read CLOSE on the lever) to theOPEN position (you can read OPEN onthe lever) (Figs. 7F, 7G).

(d) Loosen the tension adjusting nut aboutsix full turns.

(e) Raise the front wheel a few inches off theground and tap the top of the wheel with

FIGURE 7E


23

the palm of your hand to knock the wheelout of the front fork.

(f). Lafrees support stand will hold the bikeupright, but for additional safety werecommend that you place a supportunder the fork for added stability. Do notlet Lafree rock forward onto the fork sothat the fork is touching the ground asdamage can occur to the lead acidbattery.

WARNING: Lafrees lead acid batterymust never be laid on its side or tiltedin any way. If removing the front wheel,do not let Lafree rock forward onto thefork so that the fork is touching theground as damage can occur to thelead acid battery.

7.7.4 Installing a Quick-Release FrontWheel

(a) Rotate the quick-release lever so that itcurves away from the wheel (Fig. 7C).This is the OPEN position (you can readOPEN on the lever).

(b) Remove support from under fork. With thefork facing forward, insert the wheelbetween the fork blades so that the axleseats firmly to the top of the slots whichare at the tips of the fork blades - the forkdropouts. The quick-release lever shouldbe on the left side of the bicycle (Fig. 7F).

(c) Holding the quick-release lever in theOPEN position with your right hand,tighten the tension adjusting nut with yourleft hand in a clockwise direction until it isfinger tight against the fork dropout (Fig.7D).

(d) While pushing the wheel firmly to the topof the slots in the fork dropouts, and at thesame time centring the wheel rim in thefork, rotate the quick-release leverupwards and push it into the CLOSEposition (Fig. 7G). To do this use the palmof your hand while wrapping your fingersaround the right fork blade and squeezingthe lever closed using your fingers andhand together. You have the propertension if the lever leaves an impressionin the palm of your hand. The lever shouldbe parallel to the fork blade/pointingupward and curved toward the wheel.

CAUTION: If you can fully close the quick-release without wrapping your fingers aroundthe fork blade for leverage, and the lever doesnot leave a clear imprint in the palm of yourhand, the tension is insufficient. Open thelever; turn the tension adjusting nut clockwisea quarter turn; then try again.

(e) If the lever cannot be pushed all the wayto a position parallel to the fork blade,return the lever to the OPEN position.Then turn the tension adjusting nutcounterclockwise one-quarter turn andclose the lever again.

(f) Reattach the elbow cable guide to closethe brake shoes; then spin the wheel tomake sure that it is centred in the frameand clears the brake shoes.

WARNING: Secondary retentiondevices are not a substitute for correctquick-release adjustment. Failure toproperly adjust the quick-releasemechanism can cause the wheel towobble or disengage, which couldcause you to lose control and fall,which may result in serious injury.

7.7.5 Removing a Quick Release RearWheel

(a) Standing on left side (in riding position),disconnect the rear brake. (See chapter 4).

(b) Shift the rear derailleur to the outermostposition. Pull the derailleur body back withyour right hand. Rotate the quick releaselever to the OPEN position. (Fig 7D).

(c) Lift the rear wheel form the ground, andwith the derailleur still pulled back, pushthe wheel forward and down until thewheel slides from the dropouts.

7.7.6 Installing a Quick Release RearWheel

(a) Shift the rear derailleur to the high gear(smallest gear on rear wheel) then, pullthe derailleur body back with your righthand. Rotate the lever to the OPENposition (Fig. 7D). The lever should be onthe opposite side of the wheel to thederailleur and the wheel gears.

(b) Put the chain on the top of the smallestgear. Then, insert the wheel into thedropouts of Lafrees frame until the wheelis aligned with the frames seat tube andthere is uniform clearance between thebrake shoes.

(c) Tighten the adjusting nut until it is fingertight against the frame dropout; thenrotate the lever towards the front of thebike until it is parallel to the framesseatstay tube and is curved toward thewheel (Fig. 7H).

NOTE: check the distance between the framemounted speed sensor, and the wheelsmagnet plate at this time. The recommendeddistance is 1-2mm.

Some models are equipped with internal gearhub. Removing and installing the rear wheelwith internal gear hub requires special tools.Consult your dealer.

7.8 Seat Post Quick-ReleaseLafree is equipped with a quick-release seatpost binder for easy seat height adjustmentfor a variety of riders. The seat post quick-release binder works exactly like the wheelquick-release (Section 7.7). While a quick-release looks like a long bolt with a lever onone end and a nut on the other, the quick-release uses a cam action to firmly clamp theseat post (Fig. 4B).

WARNING: Riding with an improperlytightened seat post can allow thesaddle to turn or move and cause youto lose control and fall. We advise thatyou:

1. Ask your dealer to show you how tocorrectly clamp your seat post.

2. Learn and apply the correcttechnique for clamping your seatpost quick-release.

3. Check that the seat post is securelyclamped before you attempt to rideyour bike.

7.8.1 Adjusting the quick-releasemechanism

The action of the quick-release cam squeezesthe seat collar around the seat post to holdthe seat post securely in place. The amount ofclamping force is controlled by the tensionadjusting nut. Turning the tension adjustingnut clockwise while keeping the cam leverfrom rotating increases clamping force; turningit counterclockwise while keeping the camlever from rotating reduces clamping force.Less than half a turn of the tension adjustingnut can make the difference between safeclamping force and unsafe clamping force.

FIGURE 7H


25

CAUTION: Holding the nut with one hand andturning the lever like a wing nut until tight willnot clamp the seat post safely. The full forceof the cam action is needed to clamp the seatpost securely.

7.9 BrakesNOTE: For most effective braking, alwaysapply both brakes simultaneously.

WARNING: Sudden or excessiveapplication of the front brake may pitchthe rider over the handlebar, whichmay cause serious injury.

7.9.1 How brakes workIts important to your safety that youinstinctively know which brake lever controlswhich brake on your bike. The braking actionof a bicycle is a function of the friction betweenthe brake surfaces - the brake shoes and thewheel rim on the front brake and internal brakeshoes on the rear roller brake. To make surethat you have maximum friction available, keepyour wheel rims and brake shoes clean andfree of lubricants, waxes or polishes.

Brakes are designed to control your speed,not just to stop the bike. Try, as much aspossible, to get used to the (strong) brakingperformance during your first ride.

Braking and traction forces changedramatically when riding on loose surfaces orin wet weather. Tyre adhesion is reduced, sothe wheels have less cornering and brakingtraction and can lock up with less brake force.Moisture or dirt on the brake shoes canreduce their ability to slow and stop the wheeleffectively. Riding more slowly will help youcontrol the bicycle in wet or rough conditions.

7.9.2 Brake Actuated Motor Shut-OffLafree is equipped with a special safetyfeature that disengages the motor assist anytime the brakes are applied. If you noticeLafrees power assisted pedals or VPCThrottle operating while the brakes areapplied, take it to your authorised Lafreedealer immediately for service.

WARNING: Always run the SelfDiagnostic test before every ride toensure Brake Actuated Motor Shut-Offfeature is operational. Riding Lafreewith a non-operational Brake ActuatedMotor Shut-Off could cause you to losecontrol and fall.

7.10 Changing GearsThe gear-changing mechanism on yourbicycle consists of:

Twist shifter on the left side of the handle bar Derailleur with sprocket or internal gear hub

7.10.1 What the gears are for Lafrees gearing is a simple yet effective wayto help you fine tune your pedal revolutions,also known as cadence. Lafrees gearing isconsidered mid-range, meaning that it isdesigned for rolling, steep terrain. Lafreespower assisted pedals and VPC Throttlemotor assist features are effective up to amaximum of 15 percent grade.

The more you ride, the more proficient you willbecome at shifting gears. You will get thegreatest fitness benefit, produce the greatestsustained power and have the greatestendurance if you learn to spin the pedals at ahigh cadence with low pedal resistance. Youwill get the least fitness benefit and have theleast endurance by pushing hard on thepedals against heavy resistance. At the sametime, this could lead to knee pain and injuries.Lafrees power assisted pedals and VPCThrottle features assist your cadence bygiving you a boost anytime the Energy Set ison and you are pedalling. However, youshould still use the gears to get the mostperformance from your legs and motor assist.Pedalling in a harder gear will cause thepower assisted pedals torque sensor to usemore energy, which can drain the availableenergy stores more quickly.

7.10.2 shifting gears with derailleurFirst and foremost, you must be pedallingforward to shift the drive chain from one gearto another.


26

CAUTION: Never move the shifter whilepedalling backward, nor pedal backward afterhaving moved the shifter. This could jam thechain and cause serious damage to thebicycle, which could also cause you to losecontrol and fall.

Lafree is equipped with a specially designedtwist shifter, located on the left side of thehandlebar to the inside of the left grip. To shiftthe drive chain into a higher gear (smallercog) and make pedal resistance harder, rotatethe shifter to a higher number on the gearindicator. To shift the drive chain into a lowergear (larger cog) and make pedal resistanceeasier, rotate the shifter to a lower number onthe gear indicator (Fig. 7I).

To best facilitate gear shifts, always shiftgears before you are on a hill. Always scanthe road or path for upcoming hills and beprepared to shift early, before the grade of thehill becomes too steep.

If pedalling becomes too difficult, engage VPCThrottle by twisting rearward/clockwise on theright-hand throttle grip while continuing topedal forward, but without pressure to thepedals. While pedalling, rotate the left-handtwist shifter forward/counterclockwise to shiftthe drive chain into an easier gear. Once in aneasier gear, disengage VPC Throttle byrotating the throttle forward/clockwise andresuming power assisted pedal by puttingmanual power to the pedals.

Whenever shifting gears, shift early, beforepedal pressure becomes harder. Failure to

utilise this technique could cause damage tothe drive chain and cogs.

7.10.3 Shifting gears with internalgear hub

With gear hub you shift the same as withderailleur. Pedal along easily without puttingpressure on the pedals. However, with gearhubs it is possible to shift while free wheelingor standing still. For proper performance makesure the VPC throttle is not engaged duringshifting gears. Gear indication is the same aswith derailleur: lower numbers for low speed,up hill and head wind, higher numbers forhigh speed, down hill and tail wind.

7.11 Tyres and Innertubes

7.11.1 TyresLafrees tyres are general-purpose in design,made for improved (paved) road surfaces.They are not designed for unimproved roadsor trails where dirt, loose rocks, or other loosedebris is present. Your dealer can help youselect new tyres once they warrantreplacement.

The size and pressure rating are marked onthe sidewall of the tyre (Fig. 7J). The part ofthis information which is most important to youis tyre pressure.

The best way to inflate a bicycle tyre to thecorrect pressure is with a bicycle pump. Yourdealer can help you select an appropriatepump.

FIGURE 7I

FIGURE 7J


7.11.2 Tyre Air ValvesLafree tyres have French valves. To inflate aFrench valve tube, loosen the little centre nuta few turns. By pushing the centre nutdownwards you can remove air from the tube.Make sure the pump matches the valve type.Contact your dealer if necessary.

7.12 SuspensionSome Lafree models are equipped with a frontsuspension fork. This suspension is designedto smooth out some of the bump forcesassociated with roads and paths. It is notdesigned to be used for jumping or otherexcessively abusive riding.

The suspension fork on Lafree is a closedunit, utilising a coil spring and elastomerbumper system. It is not designed to be useradjustable or serviceable. If, after riding Lafreefor a given period, the front suspension seemsto be working insufficiently, take your Lafree toan authorised Lafree dealer for inspection.

7.13 Rear fork lockOperating the rear fork lock mechanism (Fig7K): Push the lock pin slightly in the directionof the pin. Now rotate the pin through thewheel. Make sure not to touch the spokes.Click the pin firmly into the lock. Now you canremove the key. To open the lock, make surethe pin can rotate freely. Then, simply placeand turn the key.

7.14 Support StandLafree is equipped with a retractable (springloaded) support stand for parking and storagewhile not in use. It is extremely important thatyou always use the support stand whenparking or storing Lafree.

Never lean Lafree against anything (wall, post,fence, etc.), or lay Lafree on its side.

To park Lafree, step down on the supportsstand toe. Guide the Lafree backwards whilepressing the toe further down until the supportlocks (Fig 7L). To ride Lafree again, put yourfoot in front of the support stand and move thebike with care forward.

NOTE: Technological advances have madebicycles and bicycle components moresophisticated than ever before, and the paceof innovation is increasing. This on-goingevolution makes it impossible for this manualto provide all the information required toproperly repair and/or maintain your bicycle. Inorder to help minimise the chances of anaccident and possible injury, it is critical thatyou have any repair or maintenance which isnot specifically described in this manualperformed by your dealer.

Equally important is that your individualmaintenance requirements will be determinedby everything from your riding style togeographic location. Consult your dealer forhelp in determining your maintenancerequirements.

The amount and kinds of maintenance youcan do yourself depends on your level of skilland experience, and on whether you have thespecial tools required.

WARNING: Many bicycle service andrepair tasks require special knowledgeand tools. Do not begin anyadjustments or service on your bicycleif you have the slightest doubt aboutyour ability to properly complete them.Improper adjustment or service mayresult in damage to the bicycle or in anaccident which may cause seriousinjury.

If you want to learn about service and repairwork on your bike, you have two options:

1.Ask your dealer to recommend a book onbicycle repair.

2.Ask your dealer about the availability ofbicycle repair courses in your area, orthrough the bike shop.

Regardless of which option you select, werecommend that the first time you work onsomething on your bike, ask your dealer tocheck the quality of your work before youattempt to ride the bike. There may be a smalllabour charge for this service.

8.1 Service & MaintenanceSchedule

Some service and maintenance can andshould be performed by the owner, andrequire no special tools or knowledge beyondwhat is presented in this manual.

The following are examples of the type ofservice you can perform yourself. All otherservice, maintenance and repair should beperformed in a properly equipped facility by aqualified bicycle mechanic using the correcttools and procedures specified by themanufacturer.

1. Break-in Period: Your bike will last longerand work better if you break it in before ridingit hard. Control cables and wheel spokes maystretch or seat when a new bike is first usedand may require readjustment by your dealer.Your Mechanical Safety Check (Section 4.3)will help you identify some things that needreadjustment. But even if everything seemsfine to you, its best to take your bike back tothe dealer for a check-up. Dealers suggestyou to bring the bike in for a check-up after 30days. Another way to judge when its time forthe first check-up is to bring the bike in afterabout 10 to 15 hours of use. But if you thinksomething is wrong with the bike, take it toyour dealer before riding it again.

2. Before every ride: Mechanical SafetyCheck (see Section 4.3)

3. After every long or hard ride; if the bike hasbeen exposed to water or grit; or at leastevery 150 kilometres: Clean the bike andlightly oil the chain, freewheel cogs and rear

derailleur pulley bushings. Wipe off excess oil.Lubrication is a function of climate. Talk toyour dealer about the best lubricants and therecommended lubrication frequency for yourarea.

4. After every long / hard ride or after 10 to 20hours of riding:

Squeeze and hold the front brake and rockthe bike forward and back. If you feel aclanking or looseness with each forward orbackward movement of the bike, you mayhave a loose headset. Have your dealercheck it. A small amount of play may bepresent from the suspension forksoverlapping slider mechanisms, which isnormal. However, if you feel a significantamount of looseness or play, have yourdealer check it immediately.

Lift the front wheel off the ground and turnthe handlebar to the left and to the right afew times. If you feel any binding orroughness in the steering, you may have atight headset or the headset may need tohave grease added to the ball bearings.Please ask your dealer to check it.

Hold one pedal and rock it back and forthacross the centreline of the bike; then do thesame with the other pedal. If anything feelsloose. Please ask your dealer to check it.

Take a look at the brake shoes. If theyrestarting to look worn or are not hitting thewheel rim squarely, ask your dealer toadjust or replace them.

Check the control cables and cablehousings for any rust, kinks, or fraying. Ifyou notice any of these problems or if yourbrakes and/or shifter are not functioningsmoothly, ask your dealer to check andreplace the cables and/or wires ifnecessary.

Squeeze spokes in adjoining pairs on eitherside of each wheel between your thumband index finger. They should all have aboutthe same tension. If any feel loose, have

your dealer check the wheel for tension andtrueness.

Check the frame (particularly in the areaaround all weld joints), the handlebar, thestem and the seatpost for any deepscratches, cracks or discoloration. Theseare signs of stress-related fatigue andindicate that a part is at the end of its usefullife and needs to be replaced.

Check to make sure that all parts andaccessories are still secure, and tighten anywhich are not.

5. As required: If either brake lever fails theMechanical Safety Check (Section 4.3):restore brake lever travel by turning the brakecable adjusting barrel counterclockwise, thenlock the adjustment in by turning the barrelslock nut clockwise as far as it will go. If thelever still fails the Mechanical Safety Check,ask your dealer to check the brakes.

If the chain wont shift smoothly and quietlyfrom gear to gear: the derailleur may be out ofadjustment. The cause may be as simple as astretched control wire, in which case you cancompensate by rotating the shifter orderailleur cable adjusting barrelcounterclockwise one turn. Try shifting again.If a full turn of the cable adjusting barrel doesnot cure the problem, see your dealer.

6. Every 50 hours of riding: Take your bike toyour dealer for a check-up.

You should never go for a bike ride withoutthe following emergency equipment andknowledge:

Allen wrenches (4, 5 and 6mm), used totighten various clamping bolts that mayloosen

Patch kit and a spare inner tube

Tyre levers

Tyre pump or cartridge inflator with correcthead to fit your tyre valves

Identification (address, phone number,insurance company, emergency contact,blood type, medical allergies andconditions)

1. If you get a flat tyre: let all the air out of theinnertube (Section 7.11). Remove one side ofthe tyre from the rim by inserting a tyre leverin between the rim and base of the tyressidewall (bead). Pry the bead away from therim by pushing down on the tyre lever. Takeanother tyre lever and pry the bead off the rimapproximately 10 to 15 centimetres awayfrom where you started. A third lever may beneeded, but at this point you should be ableto begin levering the bead off the rim so thatthe entire circumference of one side of thetyre bead comes off the rim.

Remove the innertube by first removing theair valve from the rims valve hole, thenremoving the innertube. Carefully check theoutside and inside of the tyre for the cause ofthe puncture (thorn, glass shard, nail, etc.)and remove the object if it is still there. If thetyre is cut, line the inside of the tyre in thearea of the cut with something that will resistthe innertube forcing its way out of the cutonce inflated-a spare patch, a piece of innertube, a dollar bill, an energy bar wrapper, apiece of plastic milk carton, etc.

Either patch the tube (follow the instructionsin your patch kit), or use a new innertube. (Itis always a good idea to have a newinnertube as well as a patch kit in case theinnertube cannot be patched.) In case a newtire needs to be applied, the wheel needs tobe disassembled.

Before replacing the new/repaired innertube,put just enough air in to give it some shape.Starting with the air valve, install theinnertube into the tyre. Then, starting at thevalve, slip the exposed tyre bead into the rimusing downward pressure. Make sure thebead seats down below the valves thickrubber base. Next, push the tyres beaddown into the rim with your thumbs alongeither side of the circumference of the rim,not just one side. Make sure the innertube isnot being pinched by the bead. If you havetrouble getting the last few inches of beadover the edge of the rim with thumbpressure, use a tyre lever and be careful notto pinch the tube.

CAUTION: Do not use a screwdriver or anytool other than a tyre lever, as you are likely topinch and puncture the innertube.

Check to make sure the tyre is evenly seatedaround both sides of the rim and that theinnertube is inside the tyre beads. Push thevalve stem into the tyre to make sure that itsbase is seated within the tyres beads. Inflatethe tube slowly to the optimum pressure, allthe while checking to make sure that the tyrebeads stay seated in the rim. Replace thevalve cap. Replace the wheel in the bike (seeSection 7.7).

WARNING: Riding your Lafree with aflat or under-inflated tyre can seriouslydamage the rim, tyre, tube and bicycle,and can cause you to lose control andfall.

2. If you break a spoke: A wheel with a looseor broken spoke is much weaker than a fullytensioned wheel. If you break a spoke whileon a ride, you will have to ride much moreslowly and carefully as the weakened wheelcould experience additional broken spokesand become useless.

WARNING: A broken spoke seriouslyweakens the wheel and may cause it towobble, striking the brakes or theframe. Riding with a broken spoke(s)can cause you to lose control and fall.

Twist the broken spoke around the spoke nextto it to keep it from flopping around andgetting caught between the wheel and theframe. Spin the wheel to see if the rim clearsthe brake shoes/frame. If the wheel will notturn because it is rubbing against the frontbrake shoe(s), try turning the brake cableadjusting barrel(s) clockwise to slacken thecable and open up the brakes (see Section4.3.4). If the wheel still wont turn, open thebrakes quick-release (see Section 7.7) andsecure any loose cable as best you can. Walkthe bike, or if you must, ride it with extremecaution. However, it is strongly recommendedthat you do not ride with only one functioningbrake, and that you never ride with two non-operational brakes.

3. If you crash: First, check yourself forinjuries. Seek medical help if necessary. If you

are involved with another vehicle, get as muchinformation as possible from the involvedparty and any witnesses.

Next, check your bike for damage, and fixwhat you can.

When you get home, carefully perform thechecks described in Section 7 and check forany other damaged parts. All bent, scored ordiscoloured parts are suspect and should bereplaced.
