Abstract
An antitheft control apparatus for a bicycle includes a key and an antitheft control circuit. The key includes a key base, an enabling signal transmitter supported to the key base for transmitting a wireless enabling signal, a power signal receiver for receiving an external wireless power signal and a command signal transmitter supported to the key base for transmitting a wireless command signal, wherein the command signal transmitter is powered by the power signals received by the power signal receiver. The antitheft control circuit includes a lock control circuit for providing a lock control signal for at least one of locking and unlocking a bicycle antitheft device, a switch for selectively enabling the lock control circuit to provide the lock control signal, and a sensor for sensing the wireless enabling signal transmitted by the key. The switch is operatively coupled to the sensor for enabling the lock control circuit, in response to the enabling signal, to provide the lock control signal. The lock control circuit includes a power signal transmitter for transmitting the wireless power signal to the key and a command receiving circuit for receiving the wireless command signal t…
