Superlight, compact 12 gear system built for the city
At Brompton, we don’t believe that more always means more. That’s why we offer you a choice of gears. For flatter cities, short rides and even infrequent use, less and simpler is often better. But other times, you might want – or need – more. That’s where our all-new 12-speed comes in. Just like our bike, Brompton’s 12-speed gear system is unique. We’ve expertly engineered a solution that gives you more gears and more range while still fitting into our compact solution to life on two wheels.
Even more portable
Folds in less than 20-seconds – tows and rolls easier than ever. The innovative dual-locking seat post means you can steer the folded bike by the saddle. The larger, lighter Advance Roller Wheels glide from street to building. And there’s the Brompton-engineered Roller Rack . The 341-gram rack is designed around the centre of gravity to minimise the feeling of weight, making your folded bike feel like a super light suitcase.
Spec’d to perfection
The Brompton Advance Suspension block comes as standard, sharpening control and handling. Add all the other Superlight parts and the premium touchpoints to the mix, and you have a truly next-level electric experience.
Superlight 12 speed gearing system
The lowest gear ever. The highest gear ever. And lots of small steps between, making this an even more comfortable ride for touring, exploring, commuting and beyond.
Roller frame
The 341-gram frame is designed around the centre of gravity to minimise the feeling of weight. Maximum luggage capacity 10kg.
Superlight saddle
Superlight saddle with chromoly rails, carbon reinforced base and lightweight padding.
250w hub motor
The compact 250-kWh hub motor does the hard work for you.
Smart pedal assist
Start your ride. And feel the torque. The fine-tuned sensor in the bottom bracket knows exactly when to kick in (smoothly). So you can breeze up hills and cruise the flats.
Dynamo lighting
40 Lux Busch & Muller AVY LED front and rear lamp powered by the main battery.
