On my townie I get a load squarking noise when I stand up and pedal with the left pedal hard, but not when I pedal hard with my right pedal. It feels like the noise/vibration is coming from the rear hub. Any ideas?
Honestly if it depends on which pedal you're putting the power through, I'd suspect the pedals first. Are you sure there isn't too much play on the left pedal axle? Also, I had something similar once where it turned out to be the bottom bracket, so it might be worth checking that too.
