I just bought Dahon folding bike that came with a coaster brake. I'm not convinced I'll get used to it or even want to. I have a handbrake on the bike too.

I'm pretty handy but am not sure I want to disable it myself because I don't want to mess it up. I've watched a few youtubes and it doesn't look super complicated but I'm not sure I want to have a go at it.

Anybody have an idea of what an LBS might charge to do it, or is it simple enough to do myself without wrecking anything?
