Most new Brompton riders don't know how far they've ridden. This fixes that. A tiny GPS computer that clips onto your handlebar and tracks your ride in real time. Current speed, distance, time, altitude, average speed — nine data fields in total, shown on a clear LCD screen you can read at a glance. No app required, no subscription, no Bluetooth pairing. Just mount it and ride. How it works The mount attaches to your handlebar with rubber bands — no tools, no drilling. The computer clicks onto the mount and locks in place. It picks up GPS signal automatically when you start moving, and the screen updates in real time. USB-C charging, 50-hour battery life, IPX6 waterproof. When you're done, click it off the mount and drop it in your bag.
