ABSTRACT OF THE DISCLOSURE A warning device for incorporation in the handle-bar (10) of a bicycle comprises a tubular casing (14) and a transducer housing (15). The tubular casing fits inside the end of the handle-bar while the transducer housing abuts the end of the handle-bar. A flat spring member (25) with an arc-like configuration extends longitudinally outside the tubular casing to engage the inside of the handle-bar and retain the casing in its installed position. The tubular casing houses a battery cell (22) and drive circuitry (21). A piezoelectric transducer (33) mounted inside the transducer housing is connected to the circuitry to form an oscillatory circuit. A pressure operated switch (40) is mounted externally of the transducer housing, preferably carried by a switch arm (36) extending back over the end of the handle-bar. One side of the switch is connected through the spring member to one side of the cell and the other side of the switch is connected to the oscillatory circuit. Closing of the switch supplies power to the oscillatory circuit causing the transducer to generate a warning sound.
