How do you change pedals on a bike?

Answer 1

Unscrew old pedals, check that thread size is the same, lightly lube threads on new pedals, screw in. Do note that left side pedal has a reverse thread, means that it unscrews clock wise, and screws in counter-clockwise.

Answer 2

It helps greatly if you have a pedal wrench - it's custom made to be thin enough to fit in the small axle space between your pedals and the crank arms, and long enough to give you the torque required to unscrew them. I'd recommend anything from Park Tools, I picked mine up for about $15.

Secure your bike frame, either in a bike stand, by propping it against a wall, or by flipping it upsidedown and having it rest on the saddle and handlebars. It does need to be relatively sturdy or your bike will simply roll away or fall over when you try to unscrew the pedals.

Don't forget that the left pedal will be threaded backwards to prevent it from unscrewing while you pedal. This means you'll have to turn it to the right (clockwise) to loosen it, going against the usual 'righty tighty' method. Hold the wrench at an acute angle with the crank arm; this will allow you to get more leverage and turn until the pedals are loose. Then remove the right pedal normally; turning the axle to the left (counter-clockwise).

Then replace with your new pedals. Remember to grease the threads slightly to reduce wearing, and don't overtighten them; you can usually screw them in by hand, with just a few turns needed by wrench to secure them. Tighten the right pedal by turning the wrench clockwise, and tighten the left pedal by turning counter-clockwise.

Answer 3

You screw it into the crankarm, assuming the size is right(there are two to chose from). Be aware that the left pedal has a reverse thread.
