Brompton has announced its "lightest ever" folding electric bike, which weighs in at 11.2kg (25lbs) without the battery and 14.1kg (31lbs) with it. While the price for this featherweight freighter will raise eyebrows (more on that below), anyone looking for the best folding electric bike will always do well to consider Brompton.

The range of the new Electric T Line ebike is up to 90km (56 miles) on a single charge.

“The new Brompton Electric range is our answer to the evolving way we live and move. We’ve kept everything people love about Brompton — the portability, the engineering, the joy of the ride — and added the intelligence and lightness to make it easier, smarter, and even more fun," explained Will Carleysmith, Chief Design & Engineering Officer at Brompton.

"The Electric T Line in particular is a huge leap forward. It shows that it is possible to have an exceptionally light e-bike, which can stand up to the rigours of daily use, with the power of a smart system."

The ebike is built around Brompton's proprietary e-Motiq system, comprising a custom-built rear hub motor, torque sensor and detachable 345Wh battery. The battery, rather than being integrated into the frame, is housed on the front of the bike in a dedicated cover. Brompton says the e-Motiq system was first trialled on last year's G Line Electric and, after positive feedback, the company is also integrating it into the Electric C Line and Electric P Line models.

City slickers

Unlike the more rugged G Line gravel bike, the Electric T Line is made with urban environments in mind and, as such, there are a couple of useful features thrown in. The first is called Start Assist Mode and it gives riders an initial boost of power to help get the momentum going. This could be particularly useful at traffic junctions or steep hills when it often takes some pedalling to get up to a decent speed.

The second feature, Walk Assist Mode, engages the motor at 6 km/h / 3.7mph to make it easier to push the bike along whilst on foot.

The Electric T Line features a handlebar control that lets you control your lights and level of electric assistance. It also integrates ride data and, Brompton says, will begin to learn your ride habits during the first 100km (62 miles) in the saddle. After this, the bike will adapt to its rider and display updated battery and range information after every six kilometers (three-and-a-half miles).

Like all Brompton bicycles, the Electric T Line is designed and handmade at the company's factory in London, England and comes with a hefty price tag. Starting price in the U.K. is £2,999 with the U.S. pricing yet to be revealed. It likely won't be as expensive as the Electric G Line's $4,950 starting price, but don't expect it to come cheap.

The new Brompton Electric range, including the new T Line, will be available to pre-order in Europe from October 21 with U.S. pre-orders to follow in due course. While European riders will be able to shop the bikes on general sale on October 28, U.S. customers will have to wait until January 27, 2026.
