Brompton bikes are all about city riding. With each product we design and create, we are kept focused by the question ‘Will this make moving around the city by bike better?’. One of the biggest challenges for cycling in the city is navigation. Whether new to cycling or a seasoned pedaller, there is nothing more annoying than having to fragment your trip and interrupt the flow to stop for directions. Due to the geometry of the M and H handlebars, it has been, to date, a challenge to find a high quality phone mount that fitted all Brompton bikes. 

This problem is now solved with the Brompton Phone Mount, designed for specific use with a Brompton, and featuring the Quad Lock patented dual-stage lock system. 

The first phone mounting system designed specifically for a Brompton. Use with a Quad Lock case or universal adapter (supplied separately) for perfectly positioned, secure mounting when navigating the city. 

The system integrates the Quad Lock patented dual-stage lock system, the phone can be quickly attached to any Brompton handlebar type with a simple twist.  Designed with a robust nylon in a sleek black finish. 

Don’t miss the next turn or an important alert ever again, and free yourself to keep on riding.
