摘要： A power detection device for bicycles is disclosed, which comprises at least one sprocket, a sprocket base, a strain gauge, a signal processing circuit, and a wireless signal transmitting circuit, wherein the sprocket base is engaged with the sprocket, and the strain gauge is embedded in the sprocket base. The signal processing circuit is electrically connected to the strain gauge, and the wireless signal transmitting circuit is electrically connected to the signal processing circuit. The wireless signal transmitting circuit receives an electrical signal outputted by the signal processing circuit, converts it into a wireless signal, and then sends out the wireless signal. Whereby, the strain gauge can be hidden and effectively secured.
