IMPORTANT
Detach all cables from the wheel (e.g. lighting cables), otherwise you
could tear them.
If your bike is fitted with rim brakes it is sensible to release
them before you remove the front wheel. Otherwise you may
not be able to remove the front wheel.
4. Remove the front wheel.
Replacing the front wheel
1. Insert the wheel into the front fork ends.
2. Gently turn the adjustment nut on
the quick-release lever in a clockwise
direction.
3. Close the quick-release skewer by
swinging the lever back 180˚.
You will now usually be able to see the
word 'CLOSE' on the outside of the
lever.
DANGER
It should be so hard to close the quick-release skewer that you need
to use the balls of your hands (120 N: corresponds to a weight force of
12 kg). You should have the mark of the lever imprinted on your hand.
Otherwise it could open when you are cycling, which could lead to the
wheel becoming loose and cause you to fall.

are riding the bike you could be thrown off and seriously injured.
