Brompton Phone Mount – Lightweight, No Case Needed
Most phone mounts either need a special case, cover your screen, or clamp awkwardly onto the bar. This one does none of that.
Designed specifically for the Brompton handlebar post, this mount holds your phone securely by its edges — no stickers, no adapters, no special case required. Just clip your phone in and ride.
How it works
The mount clamps onto the Brompton handlebar stem and holds your phone between two adjustable arms. It fits phones between 5.6–8cm wide, which covers most modern smartphones. A ball joint lets you tilt and rotate the phone to the exact angle you need. When you fold your bike, the mount stays out of the way — no need to remove it.
Important: this mount fits the classic Brompton handlebar post used on A, C and P Line. It does not fit the T Line or G Line, which use a different stem clamp design.
