The Brompton electric folding bike
Brompton has entered the e-bike market with the announcement of its new Brompton Electric, a
familiar-looking folder based on the brand's classic design, with an added 250W front hub motor and
a battery bag which sits on the front of the bike.
The bike folds to the same size as a non-powered Brompton, with an additional 1.5L battery bag that
can be carried as a shoulder bag when it's not on the bike. The battery also features a USB charging
port for mobile devices A larger 20L bag is also available if you want to carry more stuff around.
The Brompton Electric has four modes, ranging from no assistance, through to a high level of
assistance. With a claimed range of between 25-50 miles, the bike should have enough juice for even
the lengthiest of urban commutes.
