The Electric T Line is built as the pinnacle of Brompton’s folding design, using Grade 9 titanium tubes to deliver exceptional strength-to-weight performance. The result is an e-bike that feels incredibly light to lift, carry and steer, yet remains stable and durable for daily use. The titanium main frame is paired with a carbon fork and carbon finishing kit to further sharpen handling and reduce load, giving the bike a uniquely lively ride feel for a compact electric folder.

Its geometry remains true to Brompton’s fast-reacting city DNA, with a confident stance that makes weaving through busy streets feel natural. Superlight components—including the carbon saddle, titanium seatpost and quick-release pedals—help keep the full build impressively light.

Brompton’s 4-speed drivetrain uses a direct-mount derailleur design with a simple 11–18T cassette. It’s light, low-maintenance and gives you practical gearing for flat routes, gentle climbs and stop-start riding. Brompton dual-pivot callipers provide reliable braking control, suited to the varied pace of urban travel.

The new e-Motiq system transforms the T Line’s efficiency into a smooth, responsive electric ride. The custom rear hub motor works quietly in the background, offering assistance that feels natural rather than overwhelming. The 345Wh Greenway battery supports up to 90 km of range depending on riding style and terrain, and the handlebar control screen gives clear access to assist modes and ride data.

What makes e-Motiq stand out is its ability to learn from you. Across the first 100 km the system studies your riding patterns, refining its range predictions and smoothing power delivery every few kilometres. Over time, the assistance becomes more accurate and better matched to your pace.

Portability is where the Electric T Line excels. Brompton’s SuperRoll system makes moving the folded bike easier, whether you’re gliding through a station, rolling to a lift or navigating tight indoor spaces. By adjusting the seatpost between Shopper Mode and Suitcase Mode, you can steer or tow the bike in a way that feels surprisingly effortless. Add the Roller Frame for SuperRoll+, shifting the centre of gravity for even smoother stability when folded.

With its blend of ultralight engineering, refined electric support and unmatched portability, the Electric T Line 4 Speed is built for riders who want the freedom to move through the city with ease, efficiency and a real sense of fun.
