The Bouncer from Knog makes sure it's only you riding away on your bike. A hardened steel shackle is nearly impossible to cut, grind, or freeze and its lock cylinder provides the ultimate in security. The silicone body is soft enough to protect your bike's paint job and holds up in the sun thanks to the UV resistant qualities. It even comes with three keys in case one goes missing.
