Innovation
Lightweight Frame

Double butted tubes for a lightweight frame with a distinctive and premium look.

Tailored Ergonomics

Bars, levers, cranks and saddle are tailored for the ergonomics of young riders for a comfortable and custom-made ride.

Dedicated Geometry

Inspired by our MTB’s and adapted to smaller riders for intuitive and reliable riding.

Powder Coat Finish

Powder coating is highly resistant to wear and reduces the impact on the environment with excess powder being reused rather than wasted: simply clever. A thin layer of gloss paint adds a premium finishing touch.

Control and Safety

Hydraulic brakes and high-volume tires provide control and safety on various surfaces with low rolling resistance.
