The present invention relates to a bicycle cadence sensor and a speed indicator using a three-axis accelerometer. The present invention includes a crank provided on a bicycle, an accelerometer module attached to a crank arm provided on the crank. The present invention can fundamentally prevent malfunction due to external disturbance (for example: a pressure line on an electric pole and an underground pressure line), and can minimize the error of crank rpm and bicycle velocity.
