The weight of the bike has a lot to do with how much a child enjoys riding it. That’s why the Children’s Bike Academy Grade 4 Belt 20” is really light. What’s more, it’s an ideal first bike with a gear shifter.

To make shifting of gears as easy as possible, the bike features a lever designed with children’s smaller hands in mind. As a result, little bikers will be able to enjoy the bike’s 7 speeds.

Did you know that an ergonomic bike design can help children learn proper cycling habits? That’s why Academy, in collaboration with the German Institute of Orthopedics, Osteopathy and Sports Medicine, developed an ergonomic bike design that makes pedaling easier for children, while promoting correct body posture.

Silence is golden, especially when it comes to children’s bikes. Since the Academy Grade 4 Belt features a belt instead of a chain, it’s not only silent but also easier to maintain, which means more riding time for your kid and less time spent finetuning the bike in the garage. Plus, the belt with not get your clothes dirty, and you will stay injury free (which is not always the case when dealing with the regular bike chain).

Not only does an appropriate handlebar height make it easier to actually control the bike, it also helps promote correct posture. And the Grade 4 handlebars will grow together with your child.
