ABSTRACT:
A d-c power pack incorporated within the frame of a bicycle and adapted to supply operating power to a plurality of accessories such as head and tail lamps and a safety helmet worn by the bicyclist and provided with an electronic device. The bicycle frame includes front and rear tubes bridged by upper and lower tubes to define a trapezoidal structure. The power pack is formed by a cartridge received within a section of the lower tube of the frame, the cartridge containing a set of rechargeable battery cells serially connected to an output terminal linked by an internal line to a bank of parallel-connected outlets mounted along the upper tube of the frame. Each accessory is provided with a cable terminating in a plug insertable in a respective outlet whereby the accessory is powered through this outlet. To recharge the power pack, a recharger having a similar cable is plugged into one of the outlets.
