2 ways I have found around this. One, take a strong zip tie, wire tie, push the reverse button down, and zip tie to keep it down. Thats what I used to do. All you gotta do then is pull the brake lever and shift down. Or you can PM 1badrat on this board, he made a neat little thing that keeps the reverse cable stretched, im running one of those now and it works good. All you gotta do is shift down no button, or brake handle.
