Academy Grade 4 Belt – the lightweight children's bike for beginners

The Grade 4 Belt from Academy is a 20-inch bike specifically designed for children. In collaboration with the German Institute for Orthopedics and Sports in Bielefeld, Academy aims to produce a lightweight and high-quality children's bike that is optimally tailored to kids. Ergonomics and weight have played a crucial role in its design.

Product details

For children who are learning to ride a bike, weight is a critical factor. The Grade 4 Belt from Academy weighs just 7.5 kg, making it one of the lightest children's bikes on the market. Its low weight allows the Academy Grade to handle better in turns and makes it easier for young riders to accelerate and tackle inclines. With a lightweight bike, children also need less strength to get it moving. The low step-through height of the frame enhances accessibility.
