5. BELT DRIVE
Important: A loose belt as well as an
overtightened belt may cause injury of
the rider or damage to the drive 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, pull up 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 off the right and the left maintenance covers (A).
Loosen the axle nut (B) on both ends of the flywheel
axle by two full turns. Loosen the inner adjustment nut
(D) facing the flywheel axle on each side of the flywheel.
Next, losen the lock nut (C).
Then, turn both (right and left sides) of the inner
adjustment nuts (D) on the intside of the flywheel
bracket ¼ of a turn at a time (upward on the R side and
downward on L side) until the belt is properly adjusted.
Make sure to turn both adjustment nuts exactly the
same amount to avoid misalignment of the flywheel.
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 retigthen the two axle nuts (B). At
last reattach the maintenance covers (A).
Check if belt drive is firmly tighten and does not slip
while riding under resistance load. In case that the belt
slips, proceed using the same technique as described
above. Please note that a belt drive gear never
shows slack. In case of adjustment do not apply
too much tension.
The manufacturer recommends using an ultrasonic
voltage meter adhering to a natural frequency of the belt
of 103 Hz ± 3 Hz. Ball bearing damage due to incorrect
belt tension is excluded from warranty.
