The Hexlox is a tiny stainless insert that is placed into any existing hex bolt, forming a strong and secure anti theft system, for the Brikbike saddle and seat post. The Hexlox is simply inserted and removed from the hex bolt with a coded key. This blocks the access to the hex bolt itself, protecting it from being unscrewed and preventing the removal of the saddle and seat post.

*A Hexlox key is needed to use these locks, order one here if you don't already have one. If you do already have a key that you purchased from us, please add this as a note to your order. If you have a Hexlox key from a different shop, please reach out to Hexlox directly if you want extra locks to match that key.
