A $400 repair would add 1 ½ years of pedaling to each bike.
Nobody asks how
long a weight set will take to
pay itself off.
Why is the acquisition of
energenerating bikes in
Evergreen’s best interest
?
They will contribute to Evergreen’s mission of sustainability.
They cost less than non-generative exercise
