1. Lightweight Aluminum Frame – For urban agility
This bicycle features a 16-inch folding frame made of aerospace-grade aluminum, which is significantly lighter than comparable steel frames: ideal for one-handed carrying. Precise welds ensure high frame rigidity, while the hinge design ensures long-term durability. Perfect for practical commuters.

2. Compact and Foldable – Mobility without limits
With a folded size of only 75 × 60 × 38 cm, the bike easily fits into train luggage racks, the trunk (requires only 1/4 of the space), or the office corner next to the desk. The magnetic clasp locks in seconds, and the simple folding mechanism allows the bike to be set up in under a minute.

3. SRAM X4 1x9-speed drivetrain + mechanical disc brakes
The SRAM X4 9-speed system with an 11–32T cassette ensures smooth gear changes, without chain drop on city climbs or flat sections. Mechanical disc brakes offer consistent braking power and shorten braking distances in wet conditions compared to rim brakes, while requiring minimal maintenance.

4. 16-inch wheels – Perfect balance between speed and comfort
The 16×3/8 INNOVA puncture-resistant tires feature reinforced sidewalls for protection against broken glass and gravel. The profiled, low-rolling-resistance tread pattern glides effortlessly over pavements – bumps and curbs are simply rolled over.

5. Expandable Functionality – Foldable accessory solutions
The integrated front carrier is seamlessly compatible with the foldable ROCKBROS bag (sold separately) for quick access to essentials. Compatibility with a rear rack makes the bike an ideal helper – not just for commuting, but also for your next shopping trip.
