Sec.  1512.12  Requirements for wheel hubs.

    All bicycles (other than sidewalk bicycles) shall meet the following 
requirements:
    (a) Locking devices. Wheels shall be secured to the bicycle frame 
with a positive lock device. Locking devices on threaded axles shall be 
tightened to the manufacturer's specifications.
    (1) Rear wheels. There shall be no relative motion between the axle 
and the frame when a force of 1,780 N (400 lbf) is applied symmetrically 
to the axle for a period of 30 seconds in the direction of wheel 
removal.
    (2) Front wheels. Locking devices, except quick-release devices, 
shall withstand application of a torque in the direction of removal of 
17 N-m (12.5 ft-lb).
    (b) Quick-release devices. Lever-operated quick-release devices 
shall be adjustable to allow setting the lever position for tightness. 
Quick-release levers shall be clearly visible to the rider and shall 
indicate whether the levers are in a locked or unlocked position. Quick-
release clamp action shall emboss the frame or fork when locked.
    (c) Front hubs. Front hubs not equipped with lever-operated quick-
release devices shall have a positive retention feature that shall be 
tested in accordance with the front hub retention test, Sec.  
1512.18(j)(3), to assure that when the locking devices are released the 
wheel will not separate from the fork.
