So today while I was coming back from a 2nd building at work, a lady pulled out in front of me. I dropped the bike on the right side. The exhaust pipe is nicely scratched up (will need replaced).The pedal assembly is about halfway torn off the frame weld. I THINK all it needs is welding. But truth is I have no idea. Can this be relatively easily accomplised by a "decent" welding shop? If so, would it be very expensive?
