FWD power unit for wheelchair

This is a first post for me so forgive me if this posting is incorrect in any way.

HERE'S YOUR WHEELCHAIR CHOPPER

A detachable front wheel drive power unit for use in conjunction with a wheelchair.

This is designed to allow transportation to your destination and back. At your destination your wheelchair allows you to go into your destination without the power unit. The idea uses a motorcycle tripple tree, forks, and wheel, the motor is suspended behind the front wheel a small engine is used with a centrifugal clutch driving a chain connected to the front wheel. The front wheel and forks need to be of the dual disk type. The drive sprocket is connected to one side of the wheel and the other side of the wheel is used for braking. A frame with a quick release is used to attach to the wheelchair. The front wheels of the wheelchair are lifted off the ground by a intigrated jack which also assists in the connection of the wheelchair to the frame. When disconnected the jack is used as a stable platform for the power unit. Again this is a front wheel drive unit that attaches and detaches in less than a minute.

I have a prototype that I am currently using I have traveled round trips up to 90 miles. I also have been clocked at 40 miles per hour. According to California motor vehicle code I do not require a license or registration. Although, I am not suppose to have more than 2 brake horse power or be able to exceed 30 miles per hour.........but whose going to check.
