Ok now I have a challenge I'm thinking about running a Left Hand / Right Hand Dual Drive Freewheel on my OCC Chopper & XL Chopper Builds. Here's a few pic's or rear wheel left side & right side. The right side has a freewheel sprocket and I'd like to add a freewheel sprocket to left side. Why? Answer: If this is possible I won't have to use a jackshaft to switch honda 4-stroke 50cc pit / dirt bike drive train to right side rear freewheel sprocket. I would in then have two or a Dual Drive rear freewheeling HUB / Wheel. I would still have my pedal power driven right side rear freewheeling sprocket, and on the left side I'd have a motor driven rear freewheeling sprocket at the rear wheel !!! YEAH ! The reason I'm trying to do this is that with the chinese cloned honda pit / dirtbike engine, when you place it into the frame the engine drive sprocket lines up almost perfectly with rear wheel axle. On the OCC Choppers & XL Choppers you have almost 1-1/4" thats one & one quarter inches of free space on left side of rear wheel and the Hub appears to have flange diameter of 1-1/4"s also. If anyone has suggestions or know where to purchase these please share this info. Here's the pic's of XL Chopper rear hub & wheel: Notice all this space / room for a possible left side drive freewheel sprocket. Peace Crazy Horse.
