Removing pedals from a bicycle is a relatively simple task that can be completed with a few basic tools. The most common type of pedal is the flat pedal, which is simply attached to the crank arm with a bolt. To remove a flat pedal, simply loosen the bolt with a wrench and pull the pedal off the crank arm.
Clipless pedals, which are used by many cyclists, are a bit more complicated to remove. To remove a clipless pedal, you will need to first release the tension on the pedal spring. This can be done by turning the small screw on the side of the pedal counterclockwise. Once the tension is released, you can simply pull the pedal straight off the crank arm.
