1. 20-Inch Aluminum Frame: Urban-Ready & Durable
Crafted with a 20-inch aluminum folding frame, this bike balances lightweight agility and structural rigidity. The reinforced folding hinge withstands daily use, while the larger wheels enhance stability for confident city rides and weekend exercise.
2. Quick-Fold Design, Effortless Mobility
Folded dimensions (80×70×37 cm) slip seamlessly into car trunks, subway security checks, or tight apartment spaces. The intuitive folding mechanism locks securely in seconds, with ergonomic handles for painless portability—perfect for urban commutes or spontaneous road trips.
3. 1x8 Drivetrain: Built for City Rhythm
The SHIMANO Acera 8-speed system masters stop-and-go traffic with crisp, reliable shifts. Paired with V-brakes, it delivers consistent stopping power—ideal for crowded streets, bridge climbs, or sudden obstacles. Minimal maintenance meets maximum urban practicality.
4. 20-Inch Confidence on Urban Terrain
20×3/8 puncture-resistant tires combine a reinforced anti-puncture layer with dual-purpose tread: smooth-rolling center ribs for pavement efficiency and aggressive shoulder lugs for wet cobblestones and debris. Tackle potholes, curbs, and construction zones with unwavering control.
5. Fit Size & Reliable Load
The bike size is 20 inches, suitable for riders 140–185 cm tall. The maximum weight capacity is 100 kg, making it ideal for daily commuting and outdoor riding.
