I used it with a mechanical brake and a 2 speed tranny. The 2 speed has a one way bearing in it so it doesnt apply any pressure when coasting and a mechanical brake so there was no motor brakeing pressure. Other than that I'm thinking it will be pretty tough to keep the pinion on there. Double nutting might work as long as the threads are long enough to get 2 pinions on there. Only way to know for sure is to try.
