Dahon's Formula S18 offers big performance in a small package and is an amazingly versatile bicycle ready for everything from dodging traffic on your daily commutes to cruising glorious car-free roads on your next vacation. Like all Dahons it folds in a blink, so you can always have it at the ready, parked in your closet or folded and ready to ride in the trunk of your car. And when you hop in and pedal it leaps into action with its efficient, light and nimble aluminum frame, fine 20-inch WTB wheels with great Schwalbe tires and hill-flattening 18-speed Shimano drivetrain. Plus, you'll love the all-conditions stopping power of the Avid disc brakes and the comfortable upright riding position and seat.
