exercise bike

A stationary bicycle (also known as exercise bicycle, exercise bike, spinning bike, or exercycle) is a device used as exercise equipment for indoor cycling. It includes a saddle, pedals, and some form of handlebars arranged as on a (stationary) bicycle.

A stationary bicycle is usually a special-purpose exercise machine resembling a bicycle without wheels. It is also possible to adapt an ordinary bicycle for stationary exercise by placing it on bicycle rollers or a trainer. Rollers and trainers are often used by racing cyclists to warm up before racing, or to train on their own machines indoors.
