If you're planning on doing some work on your bike, it's likely that you'll need to remove the wheels at some point. Here's a quick guide on how to do just that. To remove the front wheel, first loosen the axle nuts or quick release lever (depending on your bike). Then, lift the front of the bike off the ground and support it with your legs or a friend's shoulders. Finally, remove the wheel by pulling it straight off the axle. To remove the rear wheel, first loosen the axle nuts or quick release lever (again, depending on your bike). Then, use your left foot to push down on the pedal while simultaneously lifting up on the back of the seat. This will raise the rear tire off of the ground. Finally, pull the wheel straight back to remove it from the frame.
