I've been considering this idea for about a year now. A two wheel drive bike. Wheels driven by hydraulic motors, from hydraulic pump driven by semi stock motorcycle motor. Has this ever been done? How many would be interested in working through the complications of such a project. Due to the added weight of the hydraulics weight reductions in other areas would be beneficial. I was thinking a higher torque motor such as a V twin of some kind would best.
Ok. Let's hear what you have to say. Yes I know I'm nuts.

Interesting idea although I'm not sure what a 2wd would be useful for. Every since I saw that electric drag bike I've wondered what could be done along the lines of an electric sport bike. With no fuel tank required the lower center of gravity you could get with that should be impressive. I just wonder how far it would run on a single charge. The new breakthroughs in Lithium-Ion battery technology have opened a lot of doors for new ideas. I recently purchased a 18 volt Lithium-Ion cordless drill. So far I'm impressed by the amount of torque, reduced charge time, and less weight/size.

I've seen one-off designs for bicycles before that used shafts and gears through the frame and the forkhead.

I've also seen one using chains on a DP bike.

Both were just from web sites this guy e-mailed me a long time ago.

Anyway, it can be done if one was so inclined and had the resources.

Hydrostatic drive has been done. Not sure how the 2wd would work for street riding.

I was just thinking that a two wheel drive bike would handle better in tight corners and somewhat slippery surfaces. Plus it should provide a better launch from stand still. A two wheel drive bike should maximize both acceleration and deceleration , as well as smoothing out rougher transitions. I was thinking that a hydraulic drive to both wheels would increase control and safety. It works on all wheel drive cars. So maybe it can work on an awd bike. I don't pretend to have the money to get into this now. I'd sure like to try it though.
