Convert your Brompton bike into an eBike with the smallest and lightest eBike conversion kit in the world. It’s easy to install and compatible with all Brompton models.
Producing up to 40 Nm of torque, our hub motor helps you effortlessly climb hills and shorten journeys. The motor can assist an average adult up a steep 30% incline with ease. Coupled with our finely tuned controller algorithm, the silent Swytch motor has no drag – even when turned off.
There are two types of Power Pack, the ECO and the PRO. Their sleek and lightweight design can deliver up to 50 km of range as well as fast-charging in 2 hours. These compact Power Packs can be easily removed from your Brompton’s handlebar or luggage mount for storage and safety.

We custom build the motor wheel for your bike. If you have a Brompton you will just need to confirm you need a 16″ Brompton wheel. If you have a different folding bike e.g. Dahon, with narrow forks, then you’ll need to specify your wheel size. After you have placed your order, you can confirm this in our order customisation portal.
We offer a matte-black wheel in our order portal as an optional upgrade for an additional charge. The regular Swytch wheel comes with a silver motor, rims and spokes.
Available for both cable and hydraulic brakes, these work by stopping the power to the motor as soon as you brake, even if you are still pedalling. They are great for adventure cyclists, commuting or if you often cycle through slow-moving traffic.
Increase your range by 50 km by ordering a spare PRO Power Pack to carry with you, weighing only 2kg.
