Official Replacement Battery for Brompton Electric G Line, C Line, and P Line
The Brompton Greenway Battery is the official 345 Wh replacement and spare battery for the Brompton Electric range. Designed natively for the Electric G Line and fully compatible with Electric C Line and P Line models when paired with the current adapter frame bags and Greenway charger, it delivers 30–60 miles of range per charge and recharges fully in 5 hours. One quick click removes it from the bike — unclip, bring it inside, plug in anywhere.
Keeping a second battery on hand at home or the office effectively doubles your daily range without any change to the bike itself. The battery's top-mounted controls let you set your power assist level and manage lighting directly, without opening an app. Brompton's e-bike system is certified to the UL 2849 standard — the most comprehensive e-bike electrical safety test available — and meets NYC regulations for the safe sale and use of e-bikes and batteries.
