Abstract: There is described a quick-release arrangement for mounting a bicycle wheel (2) to a hub of a bicycle frame (1) using a single-sided mount. The quick-release arrangement includes a number of levers (12) each movable between a closed position, in which the wheel is retained to the bicycle hub, and an open position in which the wheel is freely removable. A locking ring (21) is mounted to the bicycle wheel and is rotatable between an open position and a locked position. When the locking ring (21) is in the locked position, hooks (24) on the locking ring (21) are engageable with pins (26) mounted on the levers (12), to prevent the levers (12) from moving out of their closed positions. The locking ring (21) may be mounted to a lever cover plate (18) which is fixed to the wheel and arranged so as to partially cover the levers (12) when they are in their closed positions. The lever cover plate (18) may have a window (27) through which an indicator is visible to indicate the position of the locking ring (21).
