25 Mile 36V 250W Brompton/Dahon 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.
Also available in 20" wheel size for Dahon and other folding bikes with narrow forks.
