Of all the strange ways to make a bicyle that will only exercise your right leg, even if you turn it around to change yoour foot to the other side. The right peddle is he only pedal that has any strain on it. So grind it down and exercise your right leg, the other leg goes with no push. Turn it around so t hat your left leg is now on the right pedal. No this will not work as you would have to pull the right pedal back to get any resistance. and that is not possible. So I will have a strong right leg and a weak left one!
