To remove the pedal axle from a Schwinn bicycle, you will need a pedal wrench or a 15mm wrench. First, make sure the bike is stable and secure. Then, use the wrench to turn the pedal axle counterclockwise to loosen it. Once it is loose, you can continue turning it by hand until it is completely removed from the crank arm. Repeat the process for the other pedal axle. Be sure to apply some lubricant to the threads before reinstalling the pedals to prevent them from seizing in the future. **
