4. Firmly grip the fork with your
left hand, and push the lever
over to the closed position
towards the fork, ensuring that
it does not protrude so as to
cause injury to the rider. The
lever is securely tightened
when it takes a significant
amount of force to position
it in the closed position. The
appropriate amount of force
necessary to close the lever when it is properly adjusted will
result in an imprint of the lever in the palm of your hand.
Once closed, the OPEN designation on the lever will no
longer be visible. When properly closed, it is impossible to
move unless you open it again by reversing the steps above.
If you can easily move it, open the quick release lever and
tighten the adjusting nut another 180º and try again.
5. Ensure that the brake disc is correctly inserted into the
brake callipers and is correctly adjusted.
If you are unsure about this brake set-up and
adjustment procedure, please take your A2B to your Ultra
Motor dealer and ask for assistance in adjusting the brakes.
Improperly adjusted brakes may cause reduced braking
performance, leading to an accident that could result in
serious or fatal injury and/or property damage. DO NOT ride
your vehicle if you are not confident that the brakes are
working properly.
Re-installing front wheel
1. Position the wheel in the
front fork so that the quick
release lever is located
on the left side of the
front fork.
2. Move the quick release
lever to the OPEN position
(lever curves away from the
hub) and position the wheel
in the front fork so that the
axle is located in the fork
drop-outs.
3. Turn the adjusting nut on
the right side of the hub
clockwise such that you
feel resistance to closing
the lever when the lever is
parallel to the centreline of
the hub.
