Hello everyone. I've been a lurker here for a while and learned a lot from this forum. Well here's the situation, I got into a small accident last week and ended up bending one of the crank arms. It ran fine just up until tonight when I was riding home from the beach. My bike will no longer freewheel. For a while if I pedaled enough the bike wouldn't freewheel but after about 2 minutes it would start to freewheel again. I'm at a loss at what I should do, my roommate fixes bikes for a living on the weekends at a local flea market and he says he doesn't have the tools to remove the cog that is on the bike. I have the fat tire Sondors bike from indigogo.
