Mission•To be the premier provider of specialty

bicycles with an integrated variable drive system technology.

Page 6: Selected Concept Analysis

The Problem•A traditional external system relies on:• User set-up• Maintenance• Compatibility and quality of parts

•External gear systems are prone to the elements

Page 7: Selected Concept Analysis

ProblemsFinancially Initial Cost Analysis

• Current capital status▫ Contributions

Mitch: $20,000-$50,000 Vladimir: <$1,000 Family: $75,000 Angel Investors, VC’s,

SB Bank Loans, Friends, SB Grants, etc.

• Product Pricing▫ Drive System ▫ Bicycle Line

• Breakdown▫ Legal: $200,000▫ Location: $132/sq. ft. +

building = $1.2 million▫ 6061 Aluminum: $9-

$75/ft. ▫ Supplies: $175,000▫ Operations: Salaries,

recurring payments, insurance, shipping costs and facilities.

▫ Market Research: $150,000

▫ Start-up Manufacturing: $200,000

SolutionFinancial For the Future

• SB Grants• Fools• Friends• Angel Investors • VC’s • SB Bank Loans

• How many rounds of financing, how much and when will we apply them?

• What aspect of the business should we look into after our first round of financing?

• When will we begin to break even? 2nd year, possibly?

ProblemsDesign Planning

• Potential belt slipping

• Solid works/CAD generations

• Finding the shortcomings in existing designs and finding ways to better the design

• Efficient and compact shifter control

• Develop a full CAD render of model

• Use available in house WSU expertise for design review

• Prototype and TEST!

• Fine tune and adjust design

Page 10: Selected Concept Analysis

SolutionsDesign For the Future

• Locking mechanism• Adding groves on belt and

disk to reduce slippage• Spring assisted push/pull

gear shifting mechanism• The lateral motion of the

discs will be used for shifting.

• ISIS drive bottom bracket required strength

• Weight , size

• Variable spring designs• Gears and locking

mechanisms• Commercially available

alternatives to the standard v-belt

• Shifter control layout and design

• Compatibility with existing frames

Page 11: Selected Concept Analysis

Design Space Evidence•Concept Drawings

▫ CAD models in progress•Modeling Calculations

▫ Gear ratio ranges (.75:1 - 4:1)▫ Material thickness/strength

•Research▫ Patent searches▫ Engineering handbooks and dissertations

on CVTs

Page 12: Selected Concept Analysis

Major Design Decisions•Using the variable sheave CVT

▫ Minimal mechanical complexity compared to other designs. Lightweight in comparison to hydraulic systems. Has been used successfully on snowmobiles, recreational vehicles and mopeds.

▫ The design has been patented already. Why hasn’t it been built?

•Locking position mechanism ▫ Prevent undesired drift in ratios and excessive slip.

•Utilizing spring force to move the drive disks▫ Reduce the effort exerted by the rider. The shift can be better

regulated if a standardized force is used.
