Hi, a friend of mine recently has a stiff leg (left side, no knee joint anymore) and doesn’t want to hang the motorcycle ride on the nail. Now he is looking for ways to remodel motorcycles or on a motorcycle with automatic or what else there are solutions. If jmd. has a few internet addresses or addresses on site (Niedersachen, Region Braunschweig) or even here can give some information that would be great. mfg
