DAHON continues to push the boundaries of folding bike performance with its two P18 models—the race-ready Archer P18 Ultra and the urban-focused Speed P18. Both leverage the brand’s signature K-frame geometry and innovative “Fast Lane” technology, which combines a reinforced down tube with a tension stay (“Vest Line”) to enhance frame stiffness and power transfer.
Design & Build
The Archer P18 Ultra features a sleek, road-inspired drop-bar design with a 4131 chromoly steel frame and aluminum fork. Its metallic silver finish and aerodynamic profile position it as a premium compact road bike. The Speed P18 sports a classic flat-bar layout with a 4130 chromoly frame, offering a more upright riding posture suited for city and suburban use.
Folded dimensions are nearly identical—the Archer measures 81×40×66 cm at 11.8 kg, while the Speed is slightly smaller at 80×39×66 cm and 12 kg. Both utilize DAHON’s patented KC latching mechanism for secure folding.
Drivetrain & Components
Both bikes feature Shimano Sora 2×9-speed groupsets, but the Archer comes with a full Sora road kit including integrated brake/shift levers and caliper brakes, optimized for speed and mixed terrain with a 52/36T crankset and 11-25T cassette. The Speed P18 uses a 54/46T crankset with trigger shifters and V-brakes, favoring urban sprinting over climbing flexibility.
Wheels & Performance
The Archer rides on faster-rolling 451 wheels with semi-slick tires, offering quick acceleration and stable high-speed cruising—easily maintaining 35 km/h+. The Speed uses standard 406 rims with narrow 1.35″ tires, providing agile handling ideal for city streets.
On the road, the Archer delivers a remarkably stiff and responsive ride, allowing aggressive postures and efficient power transfer. The Speed feels nimble at low speeds and excels in quick turns, though its gearing may challenge newer riders on climbs.
Verdict
Priced at ¥5,798, the Archer P18 Ultra blurs the line between folding bike and road bike, offering pro-level performance in a portable package. At ¥4,398, the Speed P18 is a spirited upgrade from the classic P8—perfect for riders seeking speed and versatility within a 30 km range.
For those who refuse to compromise between portability and performance, DAHON’s P18 series represents a compelling new chapter in folding bike evolution.
