    摘要： A modular power drive scooter, including as modular components a seat, a seat post, a mainframe, a trailer and at least one battery, is built in a manner allowing quick and easy disassembly of the scooter for compact storage. In assembled form, the seat post supports the seat and also serves as a lock pin which prevents separation of the mainframe from the trailer. The mainframe includes a front wheel, a tiller assembly for steering the scooter, and recesses for accommodating one or more batteries. The trailer includes a pair of rear wheels coupled to a differential which is driven by an electric motor, and a removable storage tray that provides access to the motor. A stem member extending from the trailer engages the mainframe in an overlapping relation whereby apertures in the stem member align with ports in the mainframe. The seat post is inserted into a selected port to determine the spacing of the seat from the tiller assembly. Removal of the seat post from an aligned aperture and port enables the mainframe and the trailer to be separated by pulling a first handle located on the stem member to pivot the trailer relative to the mainframe, and then by lifting the mainframe by a second handle to disengage coupling hooks on the mainframe from a coupling rod of the trailer.
