For nearly 20 years, Schwinn chain drive bikes have led the indoor cycling industry. Even as other companies began to use belt drives, we stayed true to our technology for one simple reason: belt drives felt nothing like riding an outdoor bike. Today, all of that is changing. There is a revolutionary new belt drive taking the outdoor bike community by storm, and we’ve adapted it and brought it indoors on the A.C. Performance Plus. This next generation system delivers guaranteed durability and virtually zero maintenance, without sacrificing the Schwinn authentic cycling feel that riders know and love.
