Use a 15-mm wrench or socket to loosen each axle nut of the
flywheel. Use a 10-mm wrench and turn each chain tensioner
bolt ¼ turn to the right. Get on the bike and check for any
play in the chain by rocking back and forth on the pedals.
Once the pedals and the flywheel are moving as one, tighten
the axle nuts on the flywheel. Make sure the flywheel
remains in alignment with the frame.
This is caused by the chain being too tight or the flywheel is
out of alignment.
Loosen each axle nut using a 15-mm wrench. Adjust the 10-
mm chain tensioner bolts to align the flywheel with the frame.
Make sure that the chain tension is adjusted properly without
being too tight. Adjust the chain tension by locating the point
where the chain is tightest during one revolution of the crank.
Check the tension; you should be able to move the chain up
and down about 3/8” (in either direction). Ensure that the
chain is properly lubricated, then test-ride the bike.
