The origin of the adapted bicycling program had its genesis in the research of Dr. Richard E. Klein at the University of Illinois in Urbana-Champaign. Richard retired from his academic career at the University of Illinois in 1998. In 1999, Richard and his wife Marjorie have formed what is called an S-Corporation under United States and Illinois law. Rainbow Trainers, Inc., the name of the corporation -- is an Illinois for-profit corporation. The name “Rainbow” was selected because of Richard’s belief that if one had a handful of bikes of varying geometries in a play area, ranging from benign and gradually up to being conventional in form – and colored according to rainbow colors to indicate level of dynamics, that the children exposed to these bikes, in the colors of the rainbow, would initiate through exploration and discovery how to ride bikes. In truth, nobody is really taught how to ride a bike, but rather most discover how to ride a bike. It is an “Ahha” experience. Our role is in creating and adjusting that environment to permit children to discover on their own how to ride a bike.

On February 26, 2007, Lose the Training Wheels, Inc., and Rainbow Trainers, Inc., entered into a mutual contract agreement whereby the program would be operated by Lose the Training Wheels, Inc.

The name "Rainbow Trainers" was an outgrowth of the dream, or conviction, that children can discover how to ride a bike if the proper environment is made available. As the child is successful, this success will bring about improvement in motor skills as well as confidence to try yet another bike, another bike in the progression of colors. This was and still is our ultimate dream, and we feel that we have made gigantic strides towards the achievement of that dream.
