ROCKBROS MBS 20 Inch Folding Bike Aluminum Alloy 8 Speed 11-32T Cassette V Brake

Why It Stands Out?

Commuter-Centric: Larger wheels provide better passing and stability than smaller folding wheels

Rain-Ready: Disc brakes outclass rim brakes in wet conditions

Puncture-resistant tires: Kenda tires reduce the risk of riding on potholes

FEATURES

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.

Quick-Fold Design, Effortless Mobility

Folded dimensions (80*70*37cm) 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.

1x8 Drivetrain: Built for City Rhythm

The SHIMANO Acera 8-speed system masters stop-and-go traffic with crisp, reliable shifts. Paired with mechanical disc brakes, it delivers consistent stopping power in rain or shine—ideal for crowded streets, bridge climbs, or sudden obstacles. Minimal maintenance meets maximum urban practicality.

20-Inch Confidence on Urban Terrain

20x3/8 puncture-resistant tires combine a reinforced anti-puncture layer with dual-purpose tread: smooth-rolling center ribs for pavement efficiency, aggressive shoulder lugs for wet cobblestones and debris. Tackle potholes, curbs, and construction zones with unwavering control.

Fit Size & Reliable Load

The bike size is 20 inches, suitable for people with a height of 140-185cm. The maximum weight capacity of the bike is 100kg, making it suitable for daily commuting and outdoor riding.
