Brompton M6L Folding Electric Bike (Lacquer Finish)

Electric and 6-speed, there really isn't anything stopping you from making the most of those two-wheeled commutes and weekend escapes on the Brompton  M6L Folding Electric Bike. At the core of this bike is a steel Bolt Blue Lacquer frame which has Brompton's L type mudguards mounted to it. The M type handlebar is an iconic Brompton shape that is designed to offer comfort, in an upright position. Brompton has also added their own saddle to the bike and 40 Lux Busch & Müller AVY front and Spanninga solo XE rear lights.

Where this bike really stands out is its electric assistance. This added boost comes in the form of a 36 volt battery, offering between 20 - 45 miles of range, depending on the setting used. This battery is housed in the included Essential bag, which sits neatly on the front of the bike. Battery range can be monitored via an LED display, while the battery's included USB port allows you to charge portable devices on the move. Schwalbe Marathon Racer tyres provide the perfect finishing touch. Grippy, durable and offering a low rolling resistance, they are geared up for the rigours of city commuting.
