A bicycle comprises a frame including a head tube, front and rear wheels, a fork rotatable within the head tube for steering, and a handlebar stem 18 including handlebars. The handlebar stem set is interlockable with the fork by means of a clutch 32, 36 in a first configuration for normal steering, and in a second configuration for storage. In the second configuration, the handlebar stem 18 is rotated about the axis of the fork from its position in the first configuration, preferably by 90°. The clutch allows movement from the first configuration to the second configuration and vice-versa without the need for tools and ensures correct alignment between the front wheel and the handlebars is maintained. Locking of the clutch may be by means of a handwheel 39.
