Sleek Design, Pro Performance
The internally routed aluminum frame combines aerospace-grade lightness with a clean, modern profile. Internal cable routing—a premium-tier feature—protects brake and gear lines from mud, rain, and debris while enhancing aesthetics. Built to rival high-end models, it offers durability and style for riders seeking value without compromise.
Tuned Control for Every Terrain
A mechanical lockout suspension fork spring preload adjustment lets you switch between efficiency and cushioning. Lock it for climbs to maximize power transfer, unlock it for descents to absorb rocks and roots. Paired with mechanical disc brakes, the calipers deliver reliable, low-maintenance stopping power—in rain, dirt, or mud.
Shimano 24-Speed Precision
Shimano Altus 3x8 drivetrain, this bike masters steep climbs and fast flats. Smooth gear shifts and a wide gear range let beginners tackle trails or commutes effortlessly, while pros appreciate the crisp responsiveness on technical sections.
Conquer Trails, Defy Flats
The 27.5x1.95" puncture-resistant tires feature a reinforced casing to repel thorns and sharp debris. Deep treads bite into loose terrain, while sidewall support boosts cornering stability. From rocky paths to urban jungles, these tires balance speed, grip, and flat protection for worry-free adventures.
Precision Fit, Trail-Tailored Sizing
The 16" (Size S) frame is for riders 160-175cm, while the 18" (Size M) frame is for riders 170-185cm. The 21" (Size L)frame for riders 175-198cm. Each size features ergonomic geometry to optimize posture and dynamic control across singletracks or endurance trails.
Please remove the protective film from the bike frame after assembly to prevent potential paint damage from prolonged adhesion.
