Ok, so i just got this DK six pack and i've had it for about a week now. The chain was a little loose today so i adjusted it, rode it and it was fine. Then I ride a few more blocks and I pedal backwards and the chain feels harder to pedal backwards. I bring it home take off the chain and everything and start turning my freewheel by hand and at some points it get kinda stuck. I think one of the bearings might be messed up. Suggestions?
Have you checked if the tyres rubbing on the frame? Just take it to a bike shop and they should be able to tell you whats wrong.
