YouTube - WheelChair With HONDA 4-Stroke 165cc
This thing is hilarious! After a few flybys you get the point and its all repetitive after that. I'd like to build one of these with an R1 engine! Wheelchair with gas engine driving on public roads would confuse a lot of people. Probably still safer than the Khandi Coco car.
Or one of these.....
