A bicycle sensor unit is provided that comprises a bicycle brake part and a sensor fixedly attached to the bicycle brake part to detect rotational behavior of a bicycle wheel. The bicycle brake part is one of a bicycle brake attachment member configured to be non-movably coupled to a bicycle frame and a bicycle brake arm configured to support a bicycle brake pad for movement against a rim of the bicycle wheel. Preferably, the sensor unit is part of a bicycle brake device that comprises both the bicycle brake attachment member and the bicycle brake arm, a bicycle brake pad and the sensor.
