A quick-release axle attachment mechanism for velocipeds and motorcycles. It has a cam lever 1-5 on each end of the axle 49. The cam rotation axis is perpendicular to the axle. The cam pushes a slide 15 inward against the drop- out 43, clamping the drop-out against the bearing jam nut 51. When the cam is rotated for wheel removal, a spring 13 continues to hold the slide against the drop- out. A safety tab 47, or other coupling surface on the drop-out, engages the slide to prevent wheel removal until the slide is pulled outward with the fingers. To remove a wheel, both cams are rotated to the slack position, then both slides are pulled outward. The double safety interlock of the two slides prevents accidental wheel release. The cam lever can be made of plastic.
