How it works

1. Determine size of socket on the bolt by inserting a regular hex tool / Allen key. If a 4 mm fits you need a Hexlox Insert 4 mm.
   
   Insert the appropriate Hexlox Insert – done! The insert prevents access with normal tools – only your key fits.

Ask: How do I find the right Hexlox sizes?
Answer: Simply insert an Allen key into the bolt:
If a 4 mm Allen key fits, you need the 4 mm Hexlox.
If a 5 mm Allen key fits, then choose the 5 mm Hexlox – and so on.

Ask: Does the system also work with non-magnetic screws?
Answer: Yes, we offer special magnetic inserts for aluminum, stainless steel or titanium screws.

Ask: Can I reorder additional Hexlox inserts?
Answer: Yes, anytime. They're compatible with your existing key.

Ask: Is my saddle secured immediately?
Answer: Yes, once the Hexlox inserts are correctly placed, spontaneous theft is made much more difficult.

Question: How safe is the Hexlox system?
Answer: The Hexlox system significantly increases the security of your bike components. There is no lock in the world that is 100% secure.– not against a thief who has enough time, motivation, and the right tools. That's the reality when it comes to security – especially with bicycles and bicycle parts.

Most thefts of bicycle parts happen spontaneously. Someone walks by a bike, sees that a saddle or wheel isn't properly secured, and grabs it. Then, of course, there are the well-organized professionals with a real plan—systematic and prepared. All lock manufacturers, including us at Hexlox, develop products specifically designed to help combat these spontaneous opportunistic thieves.

Hexlox is an anti-theft system specifically designed for bicycle components—wheels, seatposts, saddles, and other parts secured with standard Allen screws. Our solution is simple yet effective: a small magnetic insert that blocks access to the screw. Without the appropriate key, it's almost impossible to reach.

We always recommend combining Hexlox with a solid frame lock and securing your bike to something solid, like a lamppost or bike rack. Security works in layers—a single solution is never enough.
