SPINNING: Creators of Indoor Cycling When two friends started manufacturing bikes in a garage back in 1991, little did they know that their cycling-based program would one day become a fitness phenomenon. Today, Mad Dogg Athletics and the Spinning program are the worldwide leaders in indoor cycling bikes, instructor education, programs and accessories for the commercial club and studio market as well as enthusiasts looking for a great workout at home. Passion propels us. Passion created the Spinning program, and passion drives us to continue to make it the best indoor cycling program in the world. Spinning is authentic. It’s true to its cycling roots, yet refined to a simplicity that makes it the perfect program for any age or ability. The Spinning program offers a unique, time-tested experience that motivates riders to push themselves and achieve real results. Results drive you, you drive us.
