The Brompton Electric is designed to change cities; it has smart features, a sleek design and is simple to use. The bike has 4 modes, ranging from no assistance (the bike rides smoothly without the battery) through to a high level of assistance, perfect if you want to arrive fresh to a meeting or are climbing a large hill. The key features and full specification details are in the table below, which lays out all the technical information about the bike. 

Key Features

  • Custom-developed 250W front hub motor giving an extremely high performance-to-weight output.
  • Bike still folds to the same size as a non-electric Brompton.
  • To aid portability, the battery can be carried separately, integrating neatly into a shoulder bag.
  • Battery features intuitive user interface and USB charging port for mobile devices 
  • All Brompton Electric bikes come with the standard battery bag (1.5L), however, there is an additional option to buy a commuter bag (20L), which can store your larger items, e.g. a laptop
  • Smooth ride thanks to the smart, integrated torque and cadence sensor
