Why not create an electric drive that can be attached to any manual wheelchair, creating a long distance alternative for wheelchair users.
The drive will resemble a pair of headphones, with two circular hubs connected by a curved section. Each hub will contain a 24-volt motor powered by a lithium-ion battery with a range of almost 20 miles. When attached to the center of the wheelchair's wheels, the device will be able to propel the wheelchair at speeds up to 12 mph.
Steering will be controlled by leaning in the direction of desired travel, which will cause the control sensor to change the rotational force of the wheels.
