2. Turn the right hand crank arm vertically downwards as this allows the outer guard to be
removed more easily.
3. Ease the outer guard away from the inner guard taking care not to damage the protective
seals between it and the inner guard. Once free, remove the seal from the bottom of the
cover to allow a little more room for removal.
4. Carefully manoeuvre the guard, bottom first away from the frame and orientate it to fit
around the crank and the pedal. Once removed, you have full access to the drive train.
5. Refitting the chain guard is simply to carry out actions 1 to 4 in reverse.
Inner Guard
1. Follow procedure for “removing the pedal crank arms” below.
2. Undo 3 bolts fastening the inner guard to the frame.
3. To refit follow steps 1 and 2 in reverse.
Removing the Flywheel
1. Follow the procedures shown above for removing the chain guard.
2. Loosen the nuts on either side of the flywheel axle enough to allow the flywheel to move
freely in the axle slide on the frame.
3. Turn the 2 chain tensioning bolts on the front forks counter-clockwise until they are fully
removed from the flywheel bracket.
4. The flywheel axle can then be removed from the slide taking care to support its’ weight
when it drops out (40 pounds/18.2kg). Care should also be taken not to drop the flywheel
onto the frame below, as the paintwork will be damaged.
5. The chain can now be eased off over the front chain sprocket.
6. The flywheel is replaced by following steps 1 to 5 in reverse.
7. To Tension the chain, turn the chain tensioning bolts on both sides of the frame by the
same amount to ensure correct alignment. Continue to adjust in small amounts until the
chain slack is eliminated and the flywheel can rotate freely without pulling the pedals
around with it.
Replacing the Chain
1. Follow the procedures shown above for removing the outer chain guard.
2. Follow the procedures shown above for removing the flywheel.
3. Replace with new chain in a similar fashion and repeat the procedures above in reverse to
re-assemble.
4. To Tension the chain, turn the chain tensioning bolts on both sides of the frame by the
same amount to ensure correct alignment (Check the alignment by counting the marks on
the flywheel bracket on both sides of the frame). Continue to adjust in small amounts
