5. Belt drive
Important:
A loose belt as well as an over tightened
belt may cause injury of the rider or damage to the
system.
Checking belt tension
: To check for
a loose belt, sit on the saddle, place your feet on
the pedals, move the pedals until the crank arms
are horizontal. Next, push down the emergency
brake handle and hold it. Then, stand on the pedals
and rock forward and backward. There should be
no play or slip in the drive train. If there is slip or
play in the drive train, this indicates that the belt is
too loose. Correct a slipping belt drive train: To
adjust the belt, pull of the right and left maintenance
covers (A). Loosen the axle nut (B) on both sides of
the fl ywheel axel by two full turns. Loosen the inner
adjustment nut (D) facing the fl ywheel axle on each
side. Next, loosen the lock nut (C).
Then, turn both (right and left sides) of the inner
adjustment nuts (D) on the inside of the fl ywheel
bracket ¼ of a turn at a time (upward on the right;
downward on the left) until the belt is properly
adjusted. Make sure to turn both adjustment nuts
exactly the same amount to avoid misalignment of
the fl ywheel. Re-check if the amount of play or slip
in the drive train has disappeared.
Finally retighten the two outer lock nuts (C) to secure
the new adjustment and retighten the two axle nuts
(B). At last reattach the maintenance covers (A).
Check if belt drive is fi rmly tighten and does not slip
while riding under a resisted load. In case the belt
slips, proceed using the same technique described
above. Please note that a belt drive gear never
shows slack. In case of adjustment do not apply to
much tension.
The manufacturer recommends using an ultrasonic
voltage meter adhering to a natural frequency of the
belt of 3200 Hz ± 150 Hz. Ball bearing damage due
to incorrect belt tension is excluded from warranty.
