Brompton goes electric with new folding e-bike

New Brompton folding e-bike launched

Brompton has announced a new folding e-bike. Powered by a 250 watt motor in the front hub and with a 300Wh battery pack, Brompton says that the machine has a range of between 25 and 50 miles.

It says that the new e-bike has been in development for five years, with Brompton teaming up with Williams Advanced Engineering, part of the motor racing group, to help develop the motor.

Rather than bolting a battery onto the bike, Brompton’s battery pack is a stand alone item, packaged in a bag that can be clipped onto the front of the bike.

Separate battery pack improves portability and security

Carrying the battery separately reduces the bike’s weight, and means that the bike and battery can be stored separately. The battery can easily be brought to a more convenient location for storage and charging. The set-up also reduces opportunities for theft.

The bike has a claimed weight of 13.4kg while the battery weighs 2.8kg. There are three assistance levels on offer and the bike comes with a smartphone app to allow you to set your own ride settings, track mileage and record service history.

Brompton’s first run of its electric folder can be reserved now, with delivery slated for early 2018. Brompton has demo machines available at Brompton Junction London and will be showcasing the bike at selected events around the UK.

Brompton says that it will extend its launch to selected European markets, with timing dependent on UK demand.
