How to remove & insert your front wheel
First you need to uncouple the brakes, by pulling back the rubber sleeve and pinching the 2 brake arms together. Then holding the brake noodle (which leads to the break lever) unclip the arm and release.
Then using a spanner loosen the nut on the wheel hub.
Then simply slide the wheel off the forks.
Then to put the wheel back, slide it onto the forks.
Before tightening, make sure the washer is between the bike fork and the wheel hub nut.
Using a spanner tighten.
To attach the brakes, hold the brake noodle and pull the cable hook until it slides in and holds. Then pull the rubber sleeve back across.
