Brompton Cafe Lock

A clever, low-security bike lock fully integrated into your frame - always with you, never forgotten. Using a combination lock means no keys to lose, and it’s perfect for deterring opportunistic theft when you’re nearby but not watching closely—like on a train, at a café, or in a busy bar. The Cafe lock is built into an extended seatpost which is easy to swap with your existing seatpost.

Total weight including the seatpost is 622g and the total incremental weight over a standard extended seatpost is 178g.
