A reliable, budget-friendly flat-bar hybrid bike built with a lightweight aluminum frame, a smooth-shifting 21-speed Shimano drivetrain, and traditional alloy V-brakes for simple daily utility and casual fitness.

Key Highlights

Classic Curved Alloy Chassis: Handcrafted from lightweight 6061 aluminum alloy. Features a traditional curved top tube layout that optimizes standover clearance and allows for a naturally upright, strain-free riding posture.
Low-Maintenance Alloy V-Brakes: Outfitted with dependable Winzip alloy linear-pull rim brakes. Provides direct, linear stopping power that is incredibly straightforward to adjust and service over time without specialized shop tools.
Shimano 21-Speed Mechanical Drivetrain: Driven by a reliable 21-speed (3×7) Shimano gear matrix. Offers a highly practical range of gear combinations to ensure easy pedaling across flat city boulevards and minor bridge climbs.
CNC-Machined Double-Wall Rims: Features strong, lightweight alloy wheels with a dedicated silver CNC-machined outer braking surface. This engineered contact edge guarantees smoother brake pad friction and consistent tracking alignment.
External Service Architecture: Designed with classic external cable routing running cleanly along the outside of the frame tubes, making quick mechanical checks, cable replacements, and routine gear tune-ups exceptionally simple.
