Today’s invention is designed for those people who use wheelchairs but who want the freedom which cycling allows.
To enable them to enjoy some quiet transport, a small electric vehicle is attached to the rear of the bike frame.
This attempts to accelerate gradually to attain a user-defined maximum speed, irrespective of the road gradient, but with the ability to slow rapidly in response to use of the conventional brakes (by responding to the usual mechanical movement of the rear brake cable).
A user would sit on the bike saddle, strapping one or two feet to the pedals for safety.
The electric vehicle would have wheels set wide enough apart that the bike could not tip over.
