Description
Brompton Cafe Lock with Extended Seatpost – Black
The Brompton Cafe Lock Q103889 is a genuine Brompton accessory that stores a combination lock and bright red cable inside an extended seatpost. It replaces your existing seatpost, keeping a small deterrent on the bike for café breaks and other brief stops while you stay nearby.
Available from 808 Cycles, a Brompton Authorised Dealer in Singapore, at S$138 net.
Built into your everyday ride
- Integrated extended seatpost: the lock travels with your Brompton, with no separate lock to remember for a short stop.
- Keyless combination lock: unlock using a number combination rather than carrying a key.
- Visible red cable: a bright cable designed to discourage opportunistic theft.
- 178 g additional weight: compared with a standard Brompton extended seatpost; the complete assembly weighs 622 g.
Security and intended use
This is a low-security deterrent. Use it for short stops when you remain close to your bike. It does not replace a high-security lock for unattended parking. Keep your Brompton in sight whenever practical and use an appropriate separate lock when leaving it unattended.
