The main down tube (7) of the bicycle frame is able to slide into a tube section (8). The tube section (8) carries the bottom bracket bearing (18) and is linked by upper (10) and lower (9) double struts to the front steering head tube (11). A rearwards facing double strut (14) is similarly linked to the lower tube section (8) to carry the rear wheel. The main down tube is linked to a double strut (17) also supporting the rear wheel and a single forwards and downwards facing strut, (16). The single strut passes through the upper double strut (10) to link to the steering tube (11). The bottom tube section is provided with a quick release lock.
