Need help fixing cranks?

My cranks are pretty messed up, ones flared out and one goes in. Does that mean they’re bent or do I just need to pull or hit them to be the same. And if thats the case I’ve already tried and they’re not budging. I saw on something called an crank extractor. Do I need one of those? What do those do?

If they’re bent the only real course of action is to replace them. Getting square taper cranks off a unicycle will require a crank extractor tool. Square taper cranks are not expensive, but you do need a few tools to get them off and on again.

unless you want to be old school cough cough…

Your local bike shop will have the tools to remove your bent cranks however its doubtful they will have unicycle cranks in stock so check out
