glove"Engineered by SCOOL". Our developers of the ACADEMY Bikes, in cooperation with the German Institute for Orthopaedics, Osteopathy and Sports Medicine (DIOOS), under the direction of Dr. med. 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, the frames with deep and narrow bottom brackets allow for tight child-friendly leg guidance. Short cranks and the upright sitting position make it possible to put your feet on the ground at any time and still ensure an ergonomic knee position while riding.
