HOW TO ADJUST THE DRIVE BELT
If you can feel the pedals slip while you are pedaling,
even when the resistance is adjusted to the highest
level, the drive belt may need to be adjusted.
To adjust the drive belt, first unplug the power
adapter. Next, carefully tip the exercise bike onto its
left side as shown.

Using an M10 socket wrench with an extension (not
included), reach into the opening in the bottom of the
Right Shield (58) and tighten the M10 x 50mm Screw
(49) a few turns until the Drive Belt (not shown) is tight;
do not overtighten the Drive Belt.
Then, tip the exercise bike upright. Repeat this pro-
cess, if necessary, until the pedals no longer slip.
