Safe inside

Brompton Electric folds to a compact package so you store it safely inside your home or workplace.

Lightweight

The battery (2.9kg) separates with one click from the lightweight electric bike (13.7kg) making it easy to carry, even on stairs.

Arrive fresh

Smart sensor technology on the e-bike knows when to assist you. Ride up hills, into the wind and fly between meetings; always arriving fresh.

Go further and faster

Its ride position and agility are more than a match for conventional bicycles. Small wheels mean fast acceleration from red lights and increased maneoverability through busy streets.

Portable

Pack up your electric bike and store it in your car. Accepted on trains, trams and metros; a folding electric bike you can take anywhere.

Smart engineering

The system was designed together with Williams Advanced Engineering, combining their technical Formula E expertise to develop an electric bike motor that meets the complex demands of a Brompton. Smart sensor technology knows when to assist you. Customise your ride settings and track your mileage and service history using the Brompton Electric app.

Power Pack

The high quality 300Wh lithium ion battery offers a riding range of 20 - 45 miles/30 - 70 km (*). The battery integrates into the front luggage giving easy access to the user interface and USB charging port.

(*) depending on tyre pressure, riding mode, frequency of stopping and accelerating, total weight, terrain, wind and temperature.
Example: a rider of 90kg (incl. luggage) with a tyre pressure of 80PSI is expected to reach 60km in mode 1 and 30km in mode 3 on slightly rolling paved roads with occasional stopping and starting.

Controller

This is the brain of the system. A sensor in the bottom bracket measures the riders cadence and power, a sensor within the hub motor measures the speed of the bike. The system analyses this data to determine how much assistance the hub motor gives.
