ARCC Converted Brompton T Line – 4-Speed

Weighing 3.3 kg less than Brompton’s electric P-Line, our AT4 redefines what it means to be a lightweight ebike, creating a premium electric T-Line, something even Brompton have not been able to achieve.

The system uses standard Bosch professional power tool batteries making it simple to expand range, replace or upgrade.

As well as providing smoother and more progressive power delivery for confidence inspiring, electronic assistance, our Intelligent Drive System fitted to the T-Line enables us to offer the most sophisticated electric T-Line on the market.

Making use of the smart tech inside our system, your T-Line has never felt so nimble!

Converting Brompton’s lightest folding bike to an ebike

Our converted T-Line – AT4 starts life as an original Brompton T-Line full titanium frame bike.

We carefully convert it to an e-bike at our Cambridge factory; adding a motor to the front wheel, a bottom-bracket torque and cadence sensor, our Intelligent Drive System, and a standard Bosch professional power tool battery, collectively weighing 3.9kg, which allows us to achieve a weight of just 11.7kg – 3.3kg lighter than Brompton’s lightest electric bike offering. On the AT4, we have replaced the front forks with Titanium forks – perfectly matching them to your bike frame.

Each bike is inspected and tested before it leaves our factory, and we are happy to offer a 5-year warranty on the drive system and forks.

You save significantly more weight switching to the ARCC Intelligent Drive System and we are proud to say our AT4 is the lightest comprehensive electric Brompton e-bike available.
