Ultimate ride
The reengineered titanium frame makes it even more dynamic and agile - it's a joy on the road.

Beauty in the detail
Faster to fold, easier to carry. We studied every interaction with the folded bike and improved it. There's nothing like this Brompton, not even other Bromptons.

Titanium is ultra strong and ultra light. It’s the world’s number one naturally occurring metal for strength-to-weight ratio.

Being naturally corrosion resistant means high shine and zero rust in all conditions.
