At night, glowing bicycle pedals in the ride can better remind other pedestrians and vehicles. The red light can remind vehicles behind, while the yellow light before turning conveys the intend and direction of turning, which ensures the safety of cyclist.
Pedal rotation provides electric power to the motor, avoiding the need to replace the battery.
Giving turning signal by food rotation is more natural and direct.
