I was listening to an old timer talking about back in the 50's he was watching a scrambles race or whatever they called it at the time. he knew a guy who was on a Adler 2 stroke and he was watching him. guy was up front and went up a hill and then came right back at the pack as if the bike had a reverse gear. I guess the hill was steep enough that he stalled it and before you know it when he rolled backwards he'd bump started it by accident and the engine was running backwards and back at the pack he came, though not for very long as down he went.
