The world's most compact folding e-bike. Supercharged for the city. Powered by smart technology developed with Williams Advanced Engineering.

The Brompton fold

All the benefits of an e-bike, packed into the original 3-part fold. It takes around 20-seconds to transform your bike into a small compact package (585mm highx 565mm long x 270mm wide) that you can tow, stow and carry anywhere. Rush-hour trains, underground, overground, on boats or in car boots. No need to leave it outside. Just enjoy the ride.


Charge on the go

The compact Brompton Electric 300wh lithium-ion battery packs in the power. And when it comes to charging, it’s as easy as plugging in your phone. Remove the battery pack (6.4 lbs including bag) with one quick click. Plug into any regular socket. Fully charge in 4 hours*. Boost for less if you’re short on time.
