Ultra light: All ACADEMY bikes weigh less than 40% of an average child's weight. At 5.5 kg for the 16-inch model, 7.2 kg for the 20-inch, 7.9 kg for the 24-inch, and 8.6 kg for the 26-inch, they are significantly lighter than typical weights for children's and youth bikes. Ergonomic: The ACADEMY frames feature low and narrow bottom brackets, promoting a close, child-friendly leg position. Short crank arms and an upright seating position allow children to place their feet on the ground at any time, while still ensuring an ergonomic knee position while riding. Child-friendly: The better the weight and ergonomics of the bike are tailored to children, the greater their motivation to ride. This results in increased physical activity and fun. Smart: ACADEMY bikes are meticulously designed. They are equipped with child-friendly components for daily urban use while maintaining a modern and cool appearance. High quality: The lightweight, up to 3-fold conical aluminum frames and forks, along with specially manufactured aluminum components, guarantee extremely low weight classes for all ACADEMY models. The newly developed VEE TIRE Rail folding tire with a reflective strip offers excellent rolling properties with perfect grip.
