Hexlox

Sure, you could secure your bike’s components by swapping out all its bolts with security bolts. But why bother when Hexlox can crank up the safety of the bolts already on your bike? Installation is simple: push your unique key with a Hexlox at the end into your unsecured hex bolt, turn, then pull off the key. To remove, push the key into it and pull it straight out. Magnetic attraction locks it to the bolt, but since it’s magnetically shielded using magnets won’t get it out any easier than tweezers, pliers, or lock picking tools. And it’ll secure everything from your wheels to your handlebars and seat post since they’re available in most common bolt sizes, including 4mm, 5mm, and 6mm.
