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 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 8 speeds.

good children’s bike is only good if it’s really light and fully adjustable. What makes Academy bikes good is light frames and components. The lowered top frame tube makes it easier for children to mount and get off the bike.   

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.

And what about the handlebar height? That’s also one of the key factors when it comes to comfort and correct posture during the ride. The Academy Grade 4 handlebars will grow together with your child, and can easily be adjusted to make your kid feel safe and comfortable during each and every ride.
