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 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.
