1. A bicycle pedal signal detection device, operable for a pedaling signal generated by a bicycle pedal during a pedaling operation, the bicycle pedal being provided with a rotation spindle and a pedal body, the pedal body being rotatably mounted, by means of a pair of bearings, to the rotation spindle, the pedal body being combined with an end cap, the bicycle pedal signal detection device comprising:
at least one strain gauge disposed in a strain gauge disposition section defined on the rotation spindle;
a control circuit board arranged in the strain gauge disposition section of the rotation spindle and being electrically connected to the at least one strain gauge;
a rechargeable battery unit for supplying electrical power;
a contact pin assembly mounted on a vertical supporting plate located at a free end of the rotation spindle, including an anode contact pin and a cathode contact pin extended toward the end cap in an axial direction and connected to the control circuit board by an anode conductive wire and a cathode conductive wire, respectively; and
a removable battery assembly including:
a battery container positioned between the free end of the rotation spindle and the end cap for accommodating the rechargeable battery unit therein;
a contact point circuit board located between the contact pin assembly and the free end of the rotation spindle, mounted to the battery container, of which a surface that faces the free end of the rotation spindle is provided with an anode contact point and a cathode contact point electrically connected to the rechargeable battery unit; and
an electricity charging port mounted on the contact point circuit board, so that an electrical power is charged through the electricity charging port to the rechargeable battery unit; and
wherein the anode contact point and the cathode contact point of the removable battery assembly are correspondingly contacted to the anode contact pin and the cathode contact pin of the contact pin assembly, so that the electrical power of the rechargeable battery unit is supplied to the control circuit board through the anode conductive wire and the cathode conductive wire.
