There are three types of Brompton handlebar to choose from:

S-Type: This has a straight bar, with a swept-forward stem, which makes for a sporty riding position - quite like a mountain bike and similar to the Birdy riding position.

M-Type: This is the “traditional” Brompton handlebar shape, with a higher and further back bar position - much more like a city bike to ride, with good visibility.

P-Type: This is a multiposition handlebar - slightly further forward than the M-Type, but with a similar high position, and a second more aerodynamic lower position.
