I was riding home from work today and my pedal was making weird noises (almost like a screech when I pedaled). I stopped to look at it but I couldn't discover anything weird or where the noise was coming from. Sure enough, about a mile later, my pedal snapped off. Luckily, I wasn't on a main road or anything and I was able to maintain my balance. This bike has about 75 miles on it and this was kind of unexpected. I think I can fix it if I take a rubber mallet and hammer it in. I took a few pictures though because it looks a little jammed up inside the pedal. It seems like an easy fix, but I don't want to risk it happening again. Does the pedal part look broken? Should I do it myself or call the shop I bought the bike from?
