BROMPTON P-LINE M4L 4 SPEED FOLDING BIKE

The BROMPTON P-LINE M4L 4 SPEED FOLDING BIKE has a titanium rear frame and forks that make it weigh 700 g less than the equivalent steel model. The suspension block has been completely redesigned and maximizes efficiency and responsiveness by increasing pedal thrust for improved control and handling. The shock-absorbing characteristics of titanium compensate for uneven road surfaces.
The dual-lock seatpost system has two positions, fully lowered for storage or half-raised for rolling. The folded bike is easy to carry even on sidewalks or tight spaces by gripping it by the tip of the Superlight saddle, and the large, lightweight wheels glide frictionlessly even over uneven surfaces.
The gearbox is super light and compact, perfect for city riding: the 4-speed system and 60g derailleur are specially designed to fit the folded bike.
The bike mounts a lightweight and durable wheel set with a rear hub that has been completely refitted to accommodate the new compact 4-speed gearing. Hex wrench axles and a new hitch mount make it easy to disassemble the wheels for repair or maintenance.
