Cyclists use bike trainers when the conditions outside make it unsafe or unpleasant for riding. Using a trainer allows the cyclist to ride the bike indoors without moving forward. This is accomplished by placing the rear wheel on a metal roller and clamping the trainer to the rear wheel hub to prevent forward and lateral motion. Trainers are categorized by how they provide resistance.
Fluid Trainers
Fluid trainers are known for being the quietest of the trainers because no external moving parts are used. Resistance is provided by fluid against a turbine that is spun by the roller bar. As a result, the faster the cyclist pedals, the greater the resistance. Many riders prefer fluid trainers because they offer the most realistic road riding sensation. However, they have a reputation for leaking fluid so caution should be taken by putting an old towel or rubber mat under the turbine housing.
Wind Trainers
Wind trainers use a small fan to provide air resistance. The faster the cyclist pedals, the more drag is created on the fan blades. A limited amount of resistance can be applied to the rear wheel so most competitive cyclists will not use this type of trainer. Wind trainers are also the noisiest of the three types, but are often the least expensive.
Magnetic Trainers
Resistance for magnetic trainers is provided by a series of magnets and a flywheel. The resistance levels are controlled by a lever where the cyclist must dismount the bike to make any change, or electronically with the control near the bike's handlebars. Magnetic trainers are relatively quiet and are usually priced between the wind and fluid models.
Stationary Bikes
Stationary bikes are another class of bicycle trainer available to cyclists, although they are not considered true trainers. Bike trainers allow a bicycle to be temporarily converted to a stationary bicycle. Stationary bikes are dedicated, specially designed pieces of exercise equipment found in the aerobic rooms and group cycle classes of health clubs.
