Problem: Smart Release engages/disengages when pedaling
Solution: Adjust Smart Release
Attention: Only a mechanic trained to work on Schwinn
bicycles should do this procedure. Make adjustments
to the Smart Release™ mechanism only to restore
the mechanism to factory specifications. Never
overtighten.
1. Begin by riding the bike. This forces the the Smart Release™
mechanism to break free. Pedal up to a moderate speed with
little or no resistance on the flywheel while applying enough
back pressure to the cranks to release the mechanism. Repeat
this several times to ensure that the mechanism is up to
operating temperature and to feel the initial setting.
2. From the front of the bike, insert the Smart Release™ adjusting
tool into the space between the chain guard and the flywheel.
3. Rotate the flywheel until the 7mm diameter hole in the Smart
Release™ adjusting plate is visible from the front of the bike.
4. Tighten the resistance mechanism to prevent the flywheel
from rotating.
5. Place a 50 lb. dumbell or weight on the right side pedal (chain
guard side) with the crank in the 9 o'clock position.
Note: When properly adjusted, the Smart Release™
mechanism should break free allowing the crank arm
to rotate down under this amount of weight.
6. Insert the Smart Release™ Adjusting Tool so that the bend in
the tool corresponds to the shape of the flywheel.
7. Insert the pin of the tool into the hole of the Smart Release™
adjusting plate.
8. Pull the handle of the tool UP toward the top of the flywheel
to increase the release pressure (higher breakaway force)
and DOWN to decrease the release pressure (lower
breakaway force).
9. Ride the bike to test that the factory specified resistance has
been achieved.
