摘要： A device for pulling a skater including a longitudinal frame, handle bars provided at the upper end potion of the frame and a ground engaging drive wheel rotatably coupled to a lower end portion of the frame. A prime mover is mounted on the frame so as to drive the drive wheel, and a unit for controlling a rotational speed of the drive wheel is coupled thereto. An arm having at least one ground engaging jockey wheel is rotatably coupled to one end thereof and in movably connected at its opposite end to the frame in such a manner that the jockey wheel is disposed substantially rearwardly of the drive wheel when the device is in use.

摘要： A scooter has a main frame, two rear bars, a rear wheel, and a rear wheel drive mechanism. The rear bars are disposed on a rear end of the main frame. The rear wheel drive mechanism has a rechargeable battery set, an electric motor, a brake device, a first protective casing, a worm wheel, and a second protective casing. The brake device, the rear wheel, the first protective casing, the worm wheel, and the second protective casing are disposed between the rear bars. The electric motor has a drive shaft and a worm. The worm wheel has a pivot shaft passing through the first protective casing, a one-way bearing, the rear wheel, a main bearing, an auxiliary bearing, and the pivot shaft inserted in the brake device. The worm engages with the worm wheel.

摘要： A scooter is provided with a power clutch mechanism enabling the scooter to be moved by a motor of the mechanism, or by pushes made by one foot of a rider of the scooter. The mechanism has a drive wheel mounted on an output shaft of the motor which is mounted on a suspension seat. The suspension seat is pivoted to the base of the scooter such that the suspension seat is urged by an urging member of the mechanism to enable the drive wheel to disengage the rear wheel of the scooter, and that the suspension seat is not urged by the urging member to enable the drive wheel to engage the rear wheel of the scooter.
