Your first priority when locking up your bike is to secure the frame, so it can be easy to forget about the wheels and other components, leaving them vulnerable to any potential thief with an Allen key, spanner, or the ability to use a quick release. But thanks to Hexlox, you might soon be able to secure these too without the need for another lock.

Currently seeking funding on Kickstarter, Hexlox is a system that magnetically secures a second bolt head into the head of any 4mm, 5mm, or 6mm Allen bolt, meaning that the Allen bolt cannot be removed until you’ve removed the Hexlox, something which can only be done using the unique key that comes with each Hexlox.

Weighing just 2g per bolt, you shouldn’t notice the extra mass even if you’re using them on a featherweight climbing bike, and they’re pretty hard to spot once they’re on the bike. In fact, the only downside for most riders will be the fact that you’ll need to use skewers that are secured using Allen keys rather than quick releases if you want to secure your wheel.

Hexlox is currently looking to raise €20,000 on Kickstarter, and there are various packages available to backers, starting from €21 (£16) for two Hexlox bolts and a key. If the crowdfunding campain is successful, then shipping is planned for between May and June.
