want to learn to fix bikes
I know very little about bicycle mechanics and repair. This past week I picked up three bikes that someone had put out for trash pickup. They are cheap bikes, nothing fancy. Each has something wrong with it: messed up spokes, no brakes, wheel out of whack, pedals falling off, etc...
But now I officially have bikes I can screw around with. I'm 16 and before I just had my one bike. So the question- what can I do with these bikes that'll teach me everything (or at least a lot) about the makeup of bikes and how to maintain/repair them. Should I try to disassemble them, etc. I'm a definite newbie.
Any advice appreciated.
