Schwinn

Schwinn traces its roots to the bicycle maker that Ignaz Schwinn founded in Chicago in 1895; today, the fitness division is run separately from the bicycle business. It is best known for the Airdyne, an air-resistance bike with arm levers that has been built since 1978.

The lineup includes indoor bikes, upright and recumbent exercise bikes, ellipticals and treadmills. The devices are designed for home workouts, and many models can connect to training apps via Bluetooth.
