NOVELTY - A bicycle drive system (22) includes a hub motor (24) on a wheel hub (26) of a bicycle (10), a bicycle throttle control (28), a battery pack (30), and a motor controller (32). Multi-connection plugs (48) are used to connect electric wiring from the controller to each of the motor and the throttle control.    USE - A drive system for folding type bicycle.    ADVANTAGE - The bicycle drive system has reduced weight.    DETAILED DESCRIPTION - A bicycle drive system (22) comprises:    (A) a hub motor (24) mounted on a hub (26) of a wheel of a bicycle (10) and providing rotational power to the wheel, with first electric signal transmitting wires connected to, and extending from, the motor;    (B) a throttle control (28) mounted on the bicycle, with second electric signal transmitting wires connected to, and extending from, the throttle control;    (C) a battery pack (30);    (D) a motor controller (32) electrically connected to the battery pack, with third electric signal transmitting wires, and fourth electric signal transmitting wires, each connected to, and extending from, the motor controller a first, high current multiple-connector electric connection plug; and    (E) a second, multiple-connector electric connection plug which is complementary to, and removably connectable with, the first plug.    The first and second wires are connected to the first plug and the third and fourth wires are connected to the second plug, such that connection of the first and second plugs (48) to each other causes the first and fourth wires, and hence the motor and controller, to be electrically connected to each other, and causes the second and third wires, and hence the throttle control and controller, to be electrically connected to each other.
