Even when I don't pedal I feel the move to the left. Frame seems to be ok (former owner's son fell once). I wonder whether or not the wooden seat has a certain incorrect direction. Tried allready to turn the support of the seat (loosening the clamps of the support beforehand) plus loosening the clamp of the wheel and pusing the front wheel a bit to the right and the rea wheel a bit to the left, but to no avail.
Any hints what to do?
