Claim:
A scooter comprising: a frame; pedals connected to the frame and adapted to support a user; wheels connected to the frame; a pedal recovery system comprising a geartrain providing a return force on the pedals; a drivetrain coupling at least one driven wheel to the pedals, wherein motion of a first one of the pedals relative to the frame in a first direction causes rotation of the at least one driven wheel to propel the scooter forward, and further causes motion of a second one of the pedals in a second opposite direction: and said geartrain providing a return force on the pedals, and further coupling at least one driven wheel to the pedals, wherein said geartrain comprises a first return gear operable with a first one of said pedals and mounted on a first axle, a second return gear operable with said first return gear, a third return gear mounted on a second axle and operable with said second return gear, said second axle being generally parallel to said first axle, such that rotation of said first return gear in a first direction causes rotation of said third return gear in the first direction and rotation of said second return gear in a second direction, a fourth return gear mounted to said second axle and operable with said third return gear such that rotation of said third return gear in the first direction causes rotation of said fourth return gear in the first direction, and a fifth return gear mounted to said first axle and operable with said fourth return gear and a second one of said pedals such that rotation of said fourth return gear in the first direction causes rotation of said fifth return gear in the an opposing direction.
