The Cube Numove 200 is part of Cube’s elite "weight-conscious" kids' range. While the standard Cube Acid 200 is built for durability and trails, the Numove series is designed to be as light as possible to help smaller riders gain confidence and control.
At approximately 7.4 kg, it is one of the lightest 20-inch bikes on the market in its price bracket. By swapping a heavy suspension fork for a lightweight rigid aluminium one and using thinner, high-quality Schwalbe tires, Cube has created a bike that feels effortless for a child to pedal and maneuver.

Key Highlights
Weight is Everything: At ~7.4 kg, this bike is roughly 2–3 kg lighter than many competitors. For a 25 kg child, that’s a massive percentage of their body weight, making the difference between them wanting to ride up a hill or walking.
Adjustable "Growth" Stem: One of the smartest features is the adjustable stem. It allows you to move the handlebars both up and away from the rider as they grow, significantly extending the time the child can comfortably use the bike.
19mm Handlebar Diameter: Standard bike grips are often too thick for children. Cube uses a specialized 19mm diameter bar and ultra-thin "Natural Fit" grips so the child can wrap their hands fully around the controls for better safety and less hand fatigue.
Narrow Q-Factor: The distance between the pedals (Q-Factor) is narrower than standard. This keeps the child's hips and knees in a straight line, which is much more ergonomic and efficient for their developing joints.
Internal Routing & Safety: Despite being a kids' bike, it features sleek internal cable routing and lacks sharp edges or exposed bolt heads, making it safer during the inevitable tumbles.
