<p>A stabiliser system, primarily for supporting a pedal bicycle and its rider upright at the halt, comprises a spring-loaded telescopic arm (25) pivoted at its upper end adjacent the rear wheel spindle (12) and having at its lower end a cross-shaft (26) carrying stabiliser wheels (27). The arm can be lowered by back-pedalling to draw a cable (22) onto a spool (31) on the pedal spindle (18). The cross-shaft also carries a flanged roller (51). When the arm is lowered by back-pedalling as the rider comes to a halt, the cross-shaft (26) is drawn beneath the rear wheel and the tyre (13) is engaged by the roller and the rear wheel is lifted off the ground, a large part of the weight of the rider being transferred to the ground through the rear wheel, the roller, the cross-shaft and the stabiliser wheels.</p> |
