PURPOSE: A wheel and pedal sensor device for a bicycle is provided to easily control the distance between a wheel sensor and a wheel magnetic according to variable intervals between a rear wheel frame and a rear wheel. CONSTITUTION: A wheel and pedal sensor device for a bicycle comprises a body, a pedal sensor(16), a wheel sensor(20), and a positioning unit. The body comprises a reset button(30) and a battery(28). The reset button is mounted on a rear frame of a bicycle and initializes the sensors. The body embeds a near field communication module. The pedal sensor is installed in the body to measure the RPM of a pedal. The wheel sensor measures the rotational speed of a wheel. The positioning unit linearly reciprocates the wheel sensor in a horizontal line. |
