Abstract
The invention is directed to a foldable electric bicycle with power assist having a front portion attached to a rear portion via a central pivot post. The front portion maintains a steering column, handle bar system and a front wheel assembly having a front wheel and an electric power train. The rear portion includes a rear connecting arm to maintain the rear wheel. The central pivot post includes a first end that connects with the front portion and a second end which connects with the rear portion. A peddle assembly connects below the central pivot post and communicates with the rear wheel through a drive chain. A rechargeable battery capable of providing electricity to the electric power train is shaped to fit within a cavity and is located within the central pivot post. The rechargeable battery is positioned proximate the user so as to vertically align with the user's girth.
