Belt drives are extremely light. Have less maintenance, a longer service life and are impressively quiet.

• ''Engineered by SCOOL''. Developers of the ACADEMY Bikes, in cooperation with the German Institute for Orthopaedics, Osteopathy and Sports Medicine (DIOOS), under the direction of Dr. medical Andreas Elsner has succeeded in developing ultra-light junior bikes that meet the latest ergonomic requirements. All models are lighter than 40 % of a normal child's weight, and the frames with deep and narrow bottom brackets allow for narrow, child-friendly leg guidance. Short pedal cranks and the upright sitting position allow you to put your feet on the ground at all times and still ensure an ergonomic knee position while driving.

Belt drive

• Here, too, we strictly adhere to ''super light concept'' - belt drives are extremely light. Other plus points: less maintenance, a longer service life and, on top of that, very quiet, what more could you ask for?

The Stem

• The patented Syntace Vario stem grows with you in height and length. The stem principle can be continuously adjusted aour nd is 100 % stable in any position. This always guarantees an optimally adjusted seating position, which means that your Academy Bike can effortlessly grow with you.
• Adjustment range: 55 - 105 mm
• Length: 70 mm
• Flip flop: Yes
• Angle: 6 degrees

Q factor

• The Q-factor describes the overall width of the cranks and plays an important role when it comes to the efficiency of the pedaling movement. Ideally, the Q-factor on the bike should match the rider's step width. A small Q-factor is more ergonomic, while a Q-factor that is too large forces the legs into an X-position when pedaling. An ergonomically correct, round pedaling is hardly possible. The result: knee pain, rapid fatigue and faster reaching of the performance limit. The ACADEMY bikes offer one of the smallest Q-factors here and are therefore optimally designed for children to pedal.

Frame

• The weight of a bike has a significant influence on the fun and enthusiasm of children. A good children's bike is only a good children's bike if it is really light and optionally adaptable! With Academy Bikes, we achieve this goal with light frames and components and even go one better. The lowered top tube offers a low step-through height, which makes it easier for children to get on and off.

Saddle

• One, sit! The straight seat prevents the sit bones from slipping and guarantees ideal support. The deepening of the saddle shell also relieves pressure. An optimal seat cover (not too soft and not too hard) avoids sinking in and ensures a secure seat with a lot of comfort and driving pleasure!

Tires

• Since the strength-to-weight ratio of children is focus, we rely on the light and narrow VEE Tire Skinwall Synthesis. Its cross-country profile makes it perfect for use in the city as well as for trips over gravel roads. It also looks good with the skinwall, but also offers optimal protection in traffic thanks to the reflective strips!

Why the Academy?

Ultra light

• Bicycles from the ACADEMY line stand out especially for their lightness. The weight of the bicycles for all models is 40 % less than a normal child's body weight.

Great functions

• Models are equipped with components that are adapted for everyday use in the city. Maximum safety and comfort.

Optimal settings for children

• The bike's low weight and perfectly equipped ergonomics are adapted to the needs of all children, which increases their motivation.

Ergonomics

• Cranks allow children to touch the ground at any time and develop their balance. They also have knees in an ergonomic position and the ride is thus more stable.

Originality and design

• Bicycles with a wheel size of more than 20'' are equipped with Shimano gears. The 8-speed is low-maintenance and offers riders an optimal gear.

Quality

• ACADEMY's aluminum frames and forks are 3 times stronger, but still light as a feather.
