Installation Instructions.
9. Place the chain over the pedals and rest it on the crank arm, do not put the chain onto
the sprocket teeth.
10. Place the other end of the chain onto the flywheel axle sprocket teeth.
11. Reinstall the flywheel using two service techs to carefully slide the flywheel into the
frame axle bracket. The chain adjustment bolts need to slide thru the adjustment nut
bracket holes.
TIP: You may find it easier to stand the bike frame on its front (resting on the front sta-
bilizer and handlebar) and then installing the flywheel into the axle mounting slots.
The weight of the flywheel will help to slide the flywheel into the mounting slots. Care-
fully hold the flywheel and return bike to the upright position.
