Hexlox – The World’s Smallest Lock for Bike Parts

Single Speed Bike

Protect Your Bike Components with Hexlox

Even the strongest bike lock won’t protect your valuable components from theft. Hexlox is an innovative, German-engineered anti-theft system designed to secure your bike’s wheels, saddle, seat post, handlebars, pedals, lights, and more - all with an elegant and easy-to-use solution.

How Hexlox Works

Hexlox fits seamlessly into the hex bolts already on your bike, so in most cases, there’s no need to replace any bolts. Once inserted, it forms an invisible security system, preventing thieves from tampering with your bike parts. The lock can only be removed using a unique Hexlox Key, ensuring only you have access to your secured components.

How is your saddle & seat post fastened?

Magnetic? How many? Which Size?

Magnetic - Or not? Are the hex bolts magnetic - or not? Just grab a normal fridge magnet to figure that out For non-magnetic bolts (Aluminum, Titanium, Stainless Steel) you need to pick our Hexlox For Non-Magnetic Bolts

How Many Bolts? - How many hex bolts on your saddle? (We recommend that you secure all bolts under the saddle)

Which Size? - Use a hex wrench/Allen Key to determine the size of the Hexlox you need. If a 5mm Allen key fits in the socket you need to get a Hexlox 5mm, etc. You also need to add a Hexlox Key to your order.
