ABSTRACT:
An recumbent bicycle or tricycle, FIG.1B, having an electric assist module mounted between the pedal mechanism and rear wheel gear mechanism. This mounting position allows the assist module to take advantage of the bicycle or tricycle's rear wheel gears to increase performance with the secondary advantage of reducing the length of the chain driving the rear wheel gears resulting in improved shifting.
