7.7 Removing and re-installing wheels 

Removing front wheel

1.  Release the front brake.
2.  Release the front hub quick-release by 

rotating the quick-release lever away 
from the hub until it is fully open. 

3.  Turn the adjusting nut on the opposite 

side of the hub from the lever ANTI-
CLOCKWISE until the nut and lever 
body clears the safety protrusions on  
the fork tip.

  *The front wheel can now be removed 

from the bike. 

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. 

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 adjus-
ted 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 A2B dealer and ask for 
assistance in adjusting the brakes. Impro-
perly 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.
