The Eerder Volt/Ampp mount is designed to work with the Eerder front light bracket for Son and Cateye lights for G line However the 10mm wide boss with 5mm hole is compatible with lots of regular front light mounts. Just be aware that on a Brompton G line there's not a lot of room for a light under the front carrier block and bag. So not every light mount will work on the G line and the fork crown has an odd shape that requires a special mount. That's why I came up with a the Eerder front light mount.

Note: The black plastic Cateye bracket is not included but it comes with the Cateye lights. It can be removed from the handlebar clamp which is included with each Cateye battery lamp of the Volt and the Ampp series. If you want an extra one for your handlebar or to use it on another bike you can opt for it on the right side of this page or get it here.
