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.
Founded in 2020 by Nick Bailey, Boost is a quintessential UK brand with a pioneering spirit and a distinct vision: to breathe new life into beloved bikes, transforming them into premium ebikes. Born out of passion, expertise and a commitment to innovation, Boost offers a seamless and enjoyable cycling experience that feels as natural as riding a regular bike.
"We aim for our cyclists to forget they're on an ebike and just enjoy the ride with a smooth Boost"
Nick Bailey created Boost as a company that would redefine the ebike sector. Bailey's motorsport passion and deep-rooted connection to British engineering have led to collaborations with industry leaders, including a partnership with Formula 1 parts manufacturers.
The ethos behind Boost is clear: create high-quality ebike conversion systems that are so integrated and intuitive that riders can focus solely on their journey, free from distractions and unnecessary complexities.
The Boost kit for Bromptons
The Boost ebike conversion kit, meticulously engineered in the UK, is a game-changer for Brompton enthusiasts.
Seamlessly integrating advanced F1 technology, this kit is a harmonious blend of form and function. It has been expertly designed to tuck into the rear triangle of your Brompton, ensuring the bike's iconic foldability remains uncompromised. Beyond the tech, the rear magic lies in the experience: around 30km* of range without sacrificing sharp steering and lively responsiveness that Brompton owners hold dear.
Designed around the unique geometry of Brompton bicycles, we use top-tier materials and advanced techniques to ensure the drive system offers an uncomprised biking experience.
The system keeps the bike's easy-folding characteristics intact. With the motor at the back, it ensure light and nimble steering. We think this is how Brompton's original designer would have wanted a Brompton ebike to feel.
Our battery casings are 3D printed in Silverstone, England, where we tap into the engineering mastery of British motorsport. The electronics are housed in a tiny 11mm high recess and the main system processor is from the same family as powers Apple's AirTags. The battery is made from ten high performance Samsung 3,500mAh cells.
A water-cut F1 spec Permaglass panel safeguards the battery enclosure, providing resilience and wear resistance.
Fastended by titanium bolts available in five colours including gold and oil slick, it adds as little as 2.5kg to the bike's weight and the battery discreetly fits the bike's frame, staying in place even when folded.
Don't just take our word for it...
"I've had plenty of experience with the Brompton Electric and Cytronex Brompton, but on the short test ride I had on the Boost I came away more impressed by this compact system."
