Removing a rear wheel is a simple task, although the gear mechanism makes it a slightly more complicated than removing the front wheel.
Open the brake.
Detach The Rear Wheel
Rotate the handle on the quick release skewer through 180 degrees from the closed position to the open position.
If the QR lever is too tight to open by hand slip a tool like a ring spanner over the lever to get more leverage.
Get behind the rear wheel
Stand behind the bike with your head on its centre-line.
Remove The Rear Wheel
Lift from the bike
Unhook the chain with your right hand to lift the bike with your left.
If the frame is heavy enough to need two hands hold the wheel between your legs until the frame is clear then gently use your feet to let it drop to the ground on the left – non-drive – side. Hang the bike by the nose of the saddle from some convenient gate, fence, tree or other item of street furniture.
If the bike has longer horizontal drop-outs you may need to push forwards with your right thumb as you lift the frame. Some frames like this – especially if they are fitted with mudguards – may not have enough room to remove the rear wheel while the tyre is inflated. In that case let the air out of the tyre to allow the rear wheel to slide forwards and out.
