The Brompton Electric P Line 4-Speed SuperRoll+ is an electric folding bike designed to make commuting and everyday travel more convenient. Combining Brompton's compact folding design with electric assistance and lightweight components, it's a practical choice for riders who regularly switch between cycling, public transport and walking.
The frame features Brompton's Advance Superlight rear frame, designed to reduce weight while maintaining the durability required for everyday riding. It incorporates a replaceable derailleur hanger, suspension block and 66mm roller wheels, helping make the bike comfortable to ride and easier to move when folded.
A carbon fibre fork further reduces weight, contributing to the Electric P Line's manageable handling and portability. The bike has a stated weight of 16kg, making it easier to lift onto trains, carry upstairs or store in smaller spaces compared with heavier electric folding bikes.
Electric assistance comes from Brompton's e-Motiq system, featuring a custom-designed rear hub motor. It provides support when accelerating, climbing hills or riding into a headwind, helping make everyday journeys less demanding.
The 345Wh Greenway battery offers a claimed range of up to 90km, depending on riding conditions and assistance settings. A full charge takes approximately five hours, making it convenient to recharge between journeys.
The system also features Brompton's Handlebar Control Screen, providing access to important ride information and electric assistance settings. Through Brompton's connected technology, the e-Motiq system learns from your riding over the first 100km, refining its range predictions every 6km thereafter to provide more personalised estimates.
The Brompton 4-speed drivetrain offers a 163% gear range, with a dedicated derailleur shifter and an 11-18T cassette. This provides a straightforward selection of gears for urban riding, allowing you to adjust your pedalling effort when tackling inclines or maintaining speed on flatter roads.
A forged 6061 aluminium crankset features a 54T chainring and integrated chainguard, helping protect clothing from contact with the drivetrain during everyday journeys.
Brompton Dual Pivot Caliper brakes provide controlled stopping power, while the 16in double-wall wheels are fitted with Continental Contact Urban tyres. These tyres are designed for everyday road use, offering a balance of grip, rolling performance and durability.
The cockpit features an aluminium stem, while the Brompton Superlight saddle provides a comfortable contact point for regular riding. An extended seatpost allows saddle height adjustment, and Superlight quick-release pedals help reduce the bike's width when stored.
One of the Electric P Line's standout features is its SuperRoll+ system. The Advance Roller Frame shifts the bike's centre of gravity when folded, helping it feel lighter and easier to manoeuvre. Four roller wheels provide a stable base, allowing the bike to be pushed, pulled or steered through railway stations, offices and other indoor spaces.
Brompton's Shopper Mode allows the folded bike to be rolled with the seatpost raised, while Suitcase Mode uses a lowered seatpost for a more compact arrangement. The bike remains securely folded while rolling, reducing the need to carry it between journeys.
With its compact folding design, electric assistance and improved portability, the Brompton Electric P Line 4-Speed SuperRoll+ is well suited to riders who want a practical alternative for commuting and city travel. Whether you're cycling to work, catching a train or exploring somewhere new, it offers a convenient way to combine riding with other forms of transport.
Specification note: The supplied information doesn't confirm the motor's maximum torque or the main frame material, so I've avoided specifying either. The claimed 90km range will vary depending on assistance level, terrain, rider weight and other riding conditions.
Occasionally, without notice, manufacturers change product design and/or specifications.
