I used to have a couple that held the bike by the left crank arm. They were real simple and compact and held the bike quite securely. I wish that I had a picture that I could post. One was commercially made from steel and a friend made me a beautiful copy out of wood. I don't have any conventional bicycles anymore so I assume my sons have them now.
