Brompton Electric G Line e-Motiq System 4-Speed Electric Folding Bike with SuperRoll+

A new type of movement - For five decades, Brompton has been transforming the way people move around cities across the world – evolving from a humble workshop in London to a global name. The Brompton story began in 1975 when Andrew Ritchie combined his ingenious engineering with craftsmanship to invent and hand build a bike like no other. Highly prized for its compact fold and lasting durability, each bike, to this day, is proudly handbuilt and quality-assured in the London Factory.

Portable - a fold designed for life - From a go-anywhere bike to a compact package in under 20-seconds. Nothings folds like a Brompton folds. Stores easily, welcome on public transport, tucks under desks, fits into your life indoors and out. There’s no need to lock and leave your Brompton - so every day just works.

That Brompton feeling - Yes, the wheels are smaller, but the ride is mighty. Nimble in traffic, quick off the mark, and smooth where it counts. Brompton bikes are expertly engineered to create a ride feel that’s confident, responsive, and seriously good fun. Different? Yes. In all the right ways.

The Brompton e-Motiq system

e-Motiq Rear Hub - With the all-new 250-watt rear hub motor you have superb traction and control. Choose from three levels of assistance and be powerfully propelled around corners, up hills, and over distances. Rigorously tested to complete five continuous laps around the world (approx 180,000 km), this e-bike confidently goes where you go.

e-Motiq Control Unit - The controller is the brains of the e-Motiq system, seamlessly detecting rider input and managing motor power with built-in safety features. Developed in-house by Brompton’s electronics and software specialists, it gives us the flexibility to refine performance and add new functionality over time. With over-the-air updates, your bike keeps getting smarter, ensuring a safe, responsive, and future-ready ride wherever you go.

e-Motiq Battery - With the 345 Wh battery, you can explore up to 90 km in one go. And when it comes to charging, it’s super easy. Remove the battery pack with one quick click and plug in anywhere.

e-Motiq Torque Sensor - The smart torque sensor knows how hard you’re pedaling and gives just the right amount of boost - making every ride feel smooth and natural, especially uphill. It’s so much fun, you don’t want to stop.

e-Motiq Handlebar Control - Super smart and compact

The all-new Brompton Electric Handlebar Control puts everything you need at your fingertips. Change your power mode, tap Start Assist, get dynamic range estimation and more, all while keeping your hands on your bars.

• During the first 100 km of riding, the e-system starts to build a good understanding of how you ride. Every 6 km, after, it personalises even further, meaning you always have a realistic view of battery life and range on your bars.
• We designed the tech to be intuitive and the control to act as one big button, so it’s a breeze to use when riding.
• The control is powered by your e-system, not Bluetooth, so the connection is always private and secure, and there’s no need to rely on your phone being charged for it to work.

SuperRoll+ Moving folded has never been this easy. Thanks to our unique engineering, your Brompton stays locked together as you roll. Lift the seatpost for Shopper Mode. Drop the seatpost for Suitcase Mode. Push. Pull. Steer. Glide. That’s SuperRoll.

Add the Roller Frame and you unlock SuperRoll+. It shifts the centre of gravity, so your bike feels lighter. Four wheels on the base mean even faster, smoother, more stable rolling. The frame weighs around 350 grammes yet has a 10kg load capacity. So you can also carry additional cargo with a bag or straps.
