Swytch Electric Bike Conversion Kit for Brompton

This Swytch electric conversion kit transforms a Brompton folding bike into an e-bike, turning your compact urban commuter into something with genuine motor assistance. The kit comes complete with everything needed to make the conversion, including a 36V 180Wh battery that provides the power. Instructions are included to guide you through the installation process. The kit is in good working order and has seen minimal use, so you're getting something that's ready to go straight away.

The 16-inch aluminium wheel size matches the Brompton's standard specification, and the hub gears remain unchanged during the conversion, so you keep the simplicity of internal gearing without needing to swap anything mechanical. The black colour matches most Brompton builds, and the overall weight distribution works well with how a Brompton folds and handles. The 180Wh battery capacity gives enough range for urban commuting without making the bike unwieldy to carry when the motor isn't running.

Once converted, the bike retains the core appeal of a Brompton—the ability to fold compactly and carry on trains or store in tight spaces—but with the option of motor assistance when you need it. This works particularly well for riders who find the pedal effort too high on hills with their regular commute, or for those mixing cycling with public transport where a bit of extra help takes the sweat out of the journey. The combination of Brompton's proven fold with electric assistance makes it suited to commuters navigating varied terrain across London and other UK cities.
