It would take 12 ½ years pedaling at
150W non-stop on each bicycle to offset

A $400 repair would add 1 ½

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 bikes…
