A human-electric hybrid vehicle is a hybrid vehicle, or more specifically a hybrid human powered vehicle, whose drivetrain consists of a human being and an electric motor/generator (and one or more electricity-storage device(s) such as a battery(ies) or ultracapacitor(s)). Some vehicles are able to operate off both human power and be plugged in to operate on battery power.
It can have characteristics of a bicycle, velomobile or other lightweight human operated vehicles with the addition of faster acceleration and regenerative braking, allowing a higher average velocity, especially in hilly terrain.
Some vehicles have a clutch and three or more wheels, allowing the operator to continue pedalling and charge up the electricity-storage device during traffic stops.
