ARCC Converted P Line Brompton

The ARCC Converted Brompton P Line (AP4) is the lightest and most refined electric Brompton available, weighing just 13.6kg—2kg lighter than Brompton’s factory e-assisted P Line. Retaining its titanium rear triangle and forks, this conversion preserves the bike’s lightweight agility while delivering smooth, intelligent power assistance.

At ARCC’s Cambridge factory, the IDS2 system is seamlessly integrated, adding only 3.9kg, which is 1.3kg lighter than Brompton’s own drive system. The front-wheel motor, torque and cadence sensors, and Bosch professional-grade battery ensure responsive, wobble-free assistance. The Launch Control Function provides an effortless boost at junctions, making city riding even smoother.

Despite its electric power, the AP4 fully folds with the battery attached and remains compatible with most Brompton bags. Every bike is inspected and tested, with the IDS2 system covered by a 5-year warranty. Additionally, ARCC will honour the remaining warranty on a converted Brompton or, if new, will uphold Brompton’s full 7-year warranty.
