Removing a wheel
-Front wheel
Unscrew the axle nuts with a 15mm wrench.
-Rear wheel
The rear wheel of your Quantum Broadway encompasses the motor. When servicing the rear
wheel have
THE ELECTRIC ASSISTANCE TURNED OFF
. To disconnect the power to the rear
hub motor, follow the cable to find the connector that is about 10cm from the axle end. This
unsnaps by pulling in opposite directions. Make sure not to pull too great of a distance. To
reconnect the cable, make sure the arrow points on each cable end line up to meet each other
as the cables are gently pushed back together. Before removing the wheel, remove the tie or
clip that secures it to the frame. After installing the rear wheel reinstall the tie or clip of the frame
so that the motor's electric cable is not lose or can get caught on anything.
The rear wheel axle nuts are 18mm. The axle has 'anti-rotation' spacers with a tab on them.
They must be used for proper spacing of the hub and to keep the hub from rotating inside the
frame. Make sure the tabs of the anti-rotation spacers line up to fill the opening at the bottom of
where the axle rests in the frame.
• When servicing the rear hub and motor give extra care to the electric cables exiting the center
of the axle on the right side. Do not crimp, cut, or pull on this cable. It may cause damage to
the motor. If it has become damaged please do not use the bicycle. See your Quantum
specialist.
• When installing a wheel be certain to carefully guide the disc brake rotor back into the caliper.
10. Tires
It is recommended that tire pressures are checked regularly. Well-inflated tires generate less
rolling resistance than underinflated tires, which means less effort when cycling and greater
battery range. Your tires are the bicycle contact points with the ground and where you maintain
your control and stability of the bicycle. Properly inflated tires support your weight and keep
traction for the bike. Underinflated tires do not provide adequate traction and cannot support
your weight thereby increasing chances of damage to the bicycle and injury to the rider.
Check your tire pressure with a pump that has a gauge. The tires need to be inflated to between
45psi and 65psi. The exact recommended tire pressure is shown on your tire sidewall.
Check the tread on your tires regularly. If the tread is almost gone, or you can see the canvas in
places, the tire will need to be replaced. If you see small cracks in the tire or get punctures often
it means you are due for a new tire. If you have a flat tire check first whether the valve has
failed. Do this by wetting the valve opening a little - if any bubbles appear, then the valve is
leaking. Check first whether the problem can be remedied by cleaning the valve. If this doesn’t
help, then you need to replace the valve core.
If the valve is working correctly and the tire still goes flat, then it has a puncture. To repair the
puncture, you need to remove the valve and the rim nut first (suspend the bike to do
this or turn it over making sure to protect the handlebar controls from damage). Press the edge
of the tire towards the center of the rim and push the first tire lever between the tire and the rim.
Take care not to pinch the inner tube while doing so to prevent further punctures. Now insert the
second tire lever right next to the first one and slide it over around a hand’s width. Repeat this
with the third one. Remove the second tire lever next and insert it next to the third one. Repeat
the procedure until you have freed the tire from the rim. Now push the valve stem out and
