A bicycle alarm system for preventing unauthorized access of a user\s bicycle comprising, in combination: a bicycle component further comprising: a box-shaped rigid housing having a rectangular back wall, a periphery formed of a top wall, bottom wall, and opposed side walls extended outwards from the back wall to define a hollow interior and a front opening, and a lid pivotally coupled to the bottom wall and positionable over the front opening and with one of the side walls further having a plurality of perforations disposed therethrough; clamp means coupled to the top wall of the housing and securable to a frame of said bicycle for holding the housing in a rigid stationary position; a key-lockable clamp adapted for securing said bicycle having a rigid tubular locking segment with two open ends and two spaced slots formed thereon between the ends, a rigid U-shaped electrically-conductive locking bracket having two free ends positionable within the slots of the locking segment, key-actuatable locking means disposed within one end of the locking segment and having a locked position for securing the locking bracket to the locking segment and an unlocked position for allowing the locking bracket to be removed from the locking segment, and an electrically-conductive alarm cable having a first terminal pair and a second terminal pair with the first terminal pair coupled to the ends of the locking bracket when placed in the locked position for defining an electrically conductive locking circuit; a key-lockable cable mechanism adapted for securing said bicycle having a rigid locking base integral with the locking segment of the key-lockable clamp and extended outwardly therefrom in a direction opposite the locking bracket, a flexible sheathed locking cable having a fixed end secured to the locking base and a free end removably securable to the locking base, and a key-actuatable locking means extended from the locking base and having a locked position for securing the free end of the locking cable to the locking base and an unlocked position for allowing the free end of the locking cable to be removed from the locking base; a motion detector extended from the housing and having an input terminal and an output terminal with the output terminal transmitting a motion detection signal when electrically energized through the input terminal and when actuated by intrusive motion of the housing with respect to the frame of the bicycle and with the output terminal transmitting no motion detection signal otherwise; controller circuitry disposed within the housing and having a first input terminal coupled to a second terminal of the alarm cable, a second input terminal coupled to the output terminal of the motion detector, and an output terminal having one mode for transmitting an alarm activation signal upon receipt of said motion detection signal and another mode for transmitting an alarm activation signal when the locking circuit is intrusively broken; a speaker coupled to the output terminal of the controller circuitry and positioned adjacent to the perforated side wall of the housing for transmitting an audible high frequency alarm signal upon receipt of the alarm activation signal; a transmitter coupled to the output terminal of the controller circuitry for transmitting an alarm signal to a remote location through space upon receipt of the alarm activation signal; an internal power source disposed within the housing for supplying electrical energy formed of a main battery and a back-up battery; a power cable having an interior terminal end and an exterior terminal end with the exterior terminal end coupleable to an external power source for receiving electrical energy therefrom; a power switch disposed within the housing and coupled between the internal power source and interior terminal of the power cable with the power switch having a first orientation for allowing electrical energy to be supplied from the main battery of the power source, a second orientation for allowing electrical energy to be supplied from the back-up battery of the power source, and a third orientation for allowing electrical energy to be supplied through the power cable; a key-actuatable lockable activation switch coupled between the power switch, the motion detector, a second terminal end of the alarm cable, and the controller circuitry and further extended through the lid of the housing, the activation switch having a locked orientation for securing the lid to the housing while simultaneously allowing delivery of electrical energy to the motion detector, the alarm cable, and the controller circuitry, the activation switch further having an unlocked orientation for allowing the lid to be opened while simultaneously preventing the delivery of electrical energy; a rigid holding clamp coupleable to the bicycle for holding the key-lockable clamp therein when not in use; and a key for locking the key-lockable clamp and for actuating and locking the activation switch; and a user component further comprising: a flexible strap having securement means on one end and securable means on the other end with the securable means coupleable with the securement means in a closed loop configuration about a wrist of a user; a rigid box-shaped container having a bottom wall coupled to the strap between the ends thereof, a top wall, and a periphery of four side walls interconnecting the top wall with the bottom wall to define a hollow interior; a receiver disposed within the container for transmitting an alarm activation signal upon receipt of the alarm signal from the transmitter of the bicycle component; a speaker disposed within the container, coupled to the receiver, and extended through the top wall of the container for transmitting an audible high-frequency alarm upon receipt of the alarm activation signal; a battery disposed within the container for supplying electrical energy; and a power switch coupled between the battery and receiver and extended through the top wall of the container and with the power switch having one orientation for allowing electrical energy to be delivered to the receiver and another orientation for preventing such delivery.
