Brompton's bikes will set you back a pretty penny, but given the customization options on offer from the British bicycle company, it's very apparent they take the folding bike business seriously. Designed for toruing, the durable frame is made from a combination of steel and titanium, and is paired with a titanium fork. Combine made-to-last parts like Brompton's Kevlar tires with a Shimano hub, and it's apparent that quality has its price.
