Update: Boost for Brompton is now available with all parts in stock. Your wheel and battery pack is built to your exact specification by our experts in London and will take 2-4 weeks.

Powerful. Lightweight. Uncompromising.

Bromptons are brilliant and our UK-made kit is the only ebike conversion that retains the bike's authentic charm. Your Brompton will continue to fold fully and using F1 technology and precision manufacturing, the kit nestles perfectly in the rear triangle adding only 2.5kg to the weight.

With the motor providing power through the rear wheel, you can enjoy around 30km* of range while maintaining the same light and nimble steering you know and love.

Installation is a breeze - it takes less than 20 minutes - and once set up, settings can be adjusted effortlessly with our complimentary mobile app. Alternatively, you can opt for an additional remote display.

"Verdict: A winner for electrifying your Brompton; lighter, cheaper and more practical than other options. 4 stars."

"This kit is fantastic. I'm massively impressed with the plastic free packaging (Brompton, take note!), the ease of installation, the fact that it fits my almost 20-year-old Brompton with ~zero adjustment, the peppy little motor, and how little the extra weight affects the balance and handling. Oh, and the calibration is excellent - it kicks in and eases off at just the right moments, both on the flats and the hills. Boost, you are absolute stars!👏👏👏"
