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 co-
vers (A).
Check if belt drive is rmly 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.

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 ywheel axle by two full turns. Loosen the inner
adjustment nut (D) facing the ywheel axle on each
side of the ywheel. Next, losen the lock nut (C).
Then, turn both (right and left sides) of the inner
adjustment nuts (D) on the intside of the ywheel
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 ywheel. Re-check if the amount of play or slip
in the drive train has disappeared.
