Abstract: An engine cover made from carbon fiber and alloy is revealed. The engine cover made from carbon fiber and alloy includes an inner layer made from alloy, an outer layer made from carbon fiber and an adhesive. A connecting edge is disposed around the inner layer made from alloy and a plurality of insertion holes is arranged at the connecting edge. A bent part is set on the outer layer made from carbon fiber and located corresponding to the connecting edge. The bent part is covered around and over the connecting edge. The adhesive is filled into each insertion hole for connecting the outer layer made from carbon fiber to the inner layer made from alloy. Thereby the engine cover has light weight, good thermal stability, radiation resistance, water resistance, corrosion resistance etc. Moreover, the shock absorption is achieved due to the adhesive.

Abstract: A scooter includes a footrest plate, a motor-mounting seat pivoted to a rear end of the footrest plate, a rear wheel, and a power driving unit mounted on the motor-mounting seat for driving the rear wheel through a transmission unit. A shock-absorbing unit is pivoted to the footrest plate adjacent to the rear end of the footrest plate and to the motor-mounting seat for absorbing shock resulting from operation of the power driving unit.

Abstract: A self-illuminating pedal assembly comprises a pedal axle, a pedal rotatably mounted around the pedal axle, a magnet securely mounted to the pedal axle, and a permanent-magnet coil securely mounted to the pedal to rotate therewith. At least one light-emitting diode is mounted to the pedal. The permanent-magnet coil is electrically connected to the light-emitting diode and surrounds the magnet. When pedaling, the permanent-magnet coil is rotated relative to the magnet to thereby generate an alternating magnetic field to cause illumination of the light-emitting diode.

Abstract: An alerting-light generating device for a bicycle includes a light-generating wheel, which is connected pivotally to the bicycle frame and which has an outer periphery that contacts frictionally a rear wheel so as to rotate synchronously with the rear wheel. The light-generating wheel is adapted to generate an alerting light when rotating.

Abstract: A roller is disposed rotatably on a roller shaft of a scooter, and has a housing which includes two housing halves that are interconnected to define an accommodation chamber therebetween. The housing halves define two shaft holes to permit extension of the roller shaft. A light-permeable rim element is sleeved fixedly on the housing. A light emitting unit is disposed within the rim element. An induction generator device is disposed within the accommodation chamber of the roller housing, and includes a mounting tube sleeved fixedly on the shaft, and a permanent magnet sleeved on the tube. A winding unit is disposed within the accommodating chamber, and includes a sheave and a coil unit that is wound on the sheave and that is in electrical connection with the light emitting unit. The sheave is sleeved rotatably on the magnet, and is fixed to the housing. Two ring-shaped conducting plates are mounted fixedly in the housing, and are in electrical and coaxial connection with the coil unit.
