Brompton P Line Urban – 4 Speed

$4,850.00 – $5,150.00

Early Spring 2026 delivery.

These will go fast. Inventory is allocated in the order deposits are received.

The 2026 P-Line 4-Speed is a total rethink of Brompton’s mid-weight champ. Steel for strength. Titanium for smoothness. Alloy for lightness. Carbon for precision. Together, they make a bike that climbs faster, corners sharper, and still folds like a dream.

Light enough to haul upstairs, tough enough for Toronto streets, and refined enough for weekend miles—the new P-Line 4-Speed is the sweet spot between everyday practicality and high-performance engineering.
