25 Mile 36V 250W 16″ Brompton eBike conversion kit.

This is the only Brompton eBike kit that is safe and easy to install, and doesn’t alter your regular Brompton in any way. It can be easily attached or removed, and once installed gives you the same performance and range as the official Brompton eBike.

Unlike other eBike kits the Swytch Brompton kit has a narrow 74mm motor that drops straight into your front forks, meaning that you don’t have to file out the forks or widen them in any way.

We strongly advise you DO NOT use any other Brompton conversion kits that require fork widening, as this is a dangerous and irreversible process that makes the Brompton warranty completely void. Our Kit does not affect your warranty because it is perfectly designed to fit with your Brompton Frame.

Also available in 20″ wheel size for Dahon and other folding bikes as a Customer Order. Contact us for more information.
