The Dahon Formula is a fast and sturdy folding bike designed for tough commutes that demand speed, portability, and endurance. The components on the Formula S18 are pretty high end, giving you smooth shifting, excellent stopping power, and low maintenance up keep. The Formula is a souped-up Dahon folding bike ready to take on any challenge.
We're big fans of durability and speed here. The Dahon Formula fits right it - delivering the fast ride we've come to wish for in folding bicycles. It's only a pound or two heavier than some of the lightest folding bicycles but we found the ride quality of the Formula S18 is well worth it.
The Formula S18 actually has a wider gear range than some of the other high performance folding bikes. That, along with the disc brakes, is what helps it stand out.
