Brompton P Line Urban Mid Bar with Rollers Folding Bike
Tuned for nipping around the city streets, the Brompton P Line Urban Mid Bar Folding Bike with Rollers prioritises low weight, with a new Superlight Advance titanium rear frame and fork slashing weight over its predecessor. Titanium is naturally more shock absorbing too, so smooths out the roads, while a new suspension block maximises pedalling efficiency.
When not on the bike, the dual locking seatpost means you can drop it fully for storage, or halfway for rolling, and the Superlight Saddle incorporates a handle for easier steering through tight spaces.
A 4-speed system uses the same range as a 3-speed, for smaller jumps between gears and improved acceleration and deceleration. Superlight wheels have been thoroughly tested in a range of conditions so are able to handle anything the weather throws at them. Removal for maintenance or puncture repairs is made easy by the hex key axles.
This bike is supplied well-equipped for riding day and night, come rain or shine, with mudguards and lights included, as well as a rear Roller Rack that carries up to 10kg of luggage, and a front carrier block adaptor for Brompton luggage.
