With the Brompton electric bike from NYCeWheels, you get the best of two worlds: the best folding bike in the world and the best electric system to run it pedal free when you wish, installed by the expert staff at NYCeWheels.

The Brompton is incredibly easy to fold up or set up, and it's light and compact. With its electric system installed by NYCeWheels, this bike still weighs just 45 pounds, making it one of the lightest electric bikes out there. That makes it fast and easy to pedal when you want to.

Small but mighty, this neat little bike can send you soaring up hills effortlessly. It's the ideal bike for city riding, whether you want to use it as a commuter bike, for running errands or just for fun. In hilly cities like San Francisco, it will help you conquer steep terrain and, if you're a commuter, it will save you from arriving at work soaked in sweat. At the same time, you'll have no parking problems or theft worries, because you can simply fold this bike up into a small package and take it inside with you.

Meanwhile, your gas bill will decline to zero. The battery has its own bag that hangs off the handlebars and is removable, so you can take the battery with you too. And the bag includes plenty of extra room for hauling documents or anything else you want to pack. This electric bike can haul passengers up to 250 pounds plus 50 pounds of cargo.

NYCeWheels can provide you an electric Brompton that we've retrofitted, or we can install an electric conversion kit on a Brompton you already own. If you're a do-it-yourselfer, we can provide you with a conversion kit to do the job yourself.

Featuring a 250W/400W brushless, gearless motor, the conversion kit also includes a Sanyo 36V lithium polymer battery. The kit also comes with a 36V brushless speed controller, a high-power smart charger with a metal casing and a cooling fan, and a comfortable thumb throttle complete with battery indicator.

If you have questions about this wonderful e-bike, just ask the staff at NYCeWheels. We'll give you straightforward answers, whether you contact us by phone or email.

NYCeWheels Electric Brompton M3L folding bike features:

  • The smallest folding electric bike - weighs just 45 lbs!
  • It's got the power to rocket up those hills
  • Powered by a thumb throttle - no pedaling necessary!

Our electric Brompton folding bike is only 18 lbs heavier than a standard Brompton bike, making it one of the lightest electric bikes in existence. It's easy to lift and carry so you can take it everywhere!

The battery is mounted in a detachable front bag with plenty of extra space for whatever you may want to take with you. The bag has a shoulder strap and weighs about 10 lbs with the battery inside. You can charge the battery fully in 4 to 5 hours.

Our electric Brompton folding bike is the easiest, most portable method of urban transportation. There's nothing that folds smaller or stands up to the quality of this English-made urban folder. An electric motor just makes it that much more fun.

If you already own a Brompton, you can have us install a electric conversion kit on it for a electric Brompton bike of your own.

Note: This kit is designed, built, and warrantied by NYCeWheels exclusively. Motor, console, controller, and wiring warrantied against manufacturing defects for a period of 1 year - battery 6 months.
