1. Built for Urban Agility
Crafted with a 16-inch aluminum folding frame, this bike is lighter than steel counterparts, allowing easy one-handed carrying. Precision welding ensures rigidity, while the hinge mechanism guarantees durability. Perfect for commuters who demand style and substance.
2. Compact Fold
Folded dimensions (75×60×38 cm) let it fit vertically in subway security scanners, car trunks (occupying 1/4 space), or office corners. The magnetic lock snaps shut in 3 seconds, with ergonomic handles for seamless transitions between buses, trains, or 4+2 road trips.
3. 1x9 Drivetrain & Disc Brakes
The SRAM X4 9-speed system offers smooth shifts with an 11–32T cassette, tackling city hills and flats without chain drops. Mechanical disc brakes deliver consistent stopping power, cutting rainy-day braking distance compared to V-brakes—all with minimal maintenance.
4. Speed Meets Comfort & Expandable Utility
16×3/8 puncture-resistant tires feature a reinforced casing to repel glass and debris, while low-resistance treads glide on pavement. The integrated front rack mount connects to ROCKBROS folding bike bags (sold separately) for quick access to essentials. Rear rack compatibility supports cargo baskets, transforming it from a commute warrior to a grocery-getter.
5. Fit Size & Reliable Load
The bike size is 16 inches, suitable for riders 140–185 cm tall. The maximum weight capacity is 100 kg, making it ideal for daily commuting and outdoor riding.
