Description

Academy Grade 4 is a lightweight 20" children's bike with high-quality components. Suitable for kids from 115 to 130 cm, aged 6 to 8 years.

The weight of the bike greatly affects how much children enjoy their ride. A quality children's bike must be light and easy to adapt. That's why the bike weighs only 7.5 kg and is equipped with quality components. The lowered top tube makes it easier for children to get on and off.

Stem
The patented Syntace Vario stem grows with children in both height and length. It is smoothly adjustable and 100% stable in every position.

Q-factor
The Q-factor describes the overall width of the cranks and plays an important role in pedaling efficiency. Ideally, the Q-factor of the bike should match the natural stride width of the rider. A smaller Q-factor is more ergonomic, while an excessively large Q-factor forces the legs into an "X" shape when pedaling. This prevents ergonomically correct, smooth pedaling, which can lead to knee pain and rapid fatigue. Academy bikes have one of the smallest Q-factors on the market and are thus ideally designed for children.

Saddle

The flat saddle provides maximum support and prevents slipping off. An optimal saddle cover (neither too soft nor too hard) prevents sinking in and provides a comfortable and secure seating position, enhancing comfort and the joy of riding!

Tires
Because Academy children's bikes consider the power-to-weight ratio of children, they feature light and narrow VEE TIRE Rail tires. Their tread pattern makes them ideal for both city riding and gravel roads. Additionally, they look good and provide the necessary visibility in traffic thanks to reflective stripes.

Designed by SCOOL

The developers of Academy bikes, in collaboration with the German Institute for Orthopaedics, Osteopathy, and Sports Medicine (DIOOS) under the leadership of Dr. Andreas Elsner, have succeeded in developing ultralight children's bikes that meet the latest ergonomic requirements. All models are lighter than 40% of the average child's weight, and frames with low and narrow center assemblies allow children to pedal effortlessly. Short cranks and an upright seating position ensure kids can always reach the ground with their feet while maintaining an ergonomic knee position when riding.
