I recently bought a used bike for an abnormally low price. Why? Because the previous owner did not understand that one of the pedals unscrews in the opposite direction to the other (look it up). The previous owner was, however, strong enough to strip the threads of one crank arm trying to remove the pedal. In the end, I had to replace the crankset. Let this be a tale of caution to those who want to remove pedals.
