Power comes from a 250W front hub motor that delivers smooth, intuitive assistance up to 25km/h. Combined with a torque-sensing bottom bracket, the bike responds naturally to your pedalling, making light work of hills, longer commutes, or just getting around quicker.
The cleverly integrated 300Wh battery pack clips on and off the front frame in seconds, and includes a USB port to charge your devices on the go. With a 4-hour full charge time and removable design, it’s as easy to plug in as your phone – and just as convenient.
The new 12-speed drivetrain is designed specifically for Brompton’s compact layout, offering a broader gear range without compromising the fold. Whether you're weaving through traffic or heading out of town for a weekend spin, the P Line keeps you covered.
Brompton’s signature fold takes under 20 seconds, with a dual-locking seatpost that turns the saddle into a handle for towing your folded bike. The Advance Roller Frame and larger 54mm wheels make rolling through stations and city streets smoother than ever. Every detail – from the quick-release pedals to the lightweight Superlight chain – has been engineered to enhance ride quality and portability.
Finished with a Velomann carbon-railed saddle, superlight headset, and compact folding handlebars, the Brompton Electric P Line 12 Speed brings a new level of performance and convenience to electric urban cycling. Whether you're a daily commuter, city explorer or multi-modal traveller, this e-bike is built to make every journey smoother.
