A resistance trainer is a type of cycling apparatus that attaches to the rear axle of a bicycle, providing resistance for indoor training. There are three types of resistance trainers: fluid, magnetic, and wind, each with varying levels of ride quality and adjustability.
The term “resistance trainer” can refer to several types of fitness equipment, but most commonly it refers to a type of cycling apparatus that is attached to the rear axle of the bicycle. This unit rests on the ground and keeps the rear wheel of the bike off the ground so that a person sitting on the bike can pedal without moving the bike forward. The resistance trainer provides resistance by applying a roller to the rear wheel, and a resistance unit provides the necessary force to allow the rider to train while cycling indoors.
There are several models of resistance trainers, and they vary in both style and function. The most basic models feature metal stands that stabilize the bike while it’s attached to the trainer, and a roller unit that adjusts so you can press against the rear wheel of the bike with varying amounts of contact. This allows a rider to use bikes with different size tires on the same training unit. The resistance unit on the trainer can use several methods to apply resistance: magnetic resistance is common, as is wind resistance and fluid resistance. The best option for realistic ride quality is smooth, but these trainers have their own drawbacks.
Fluid trainers use a viscous fluid, typically not water as it can heat up and expand during use, to provide resistance as a rotating unit within the resistance unit pushes against the fluid. This is a quiet way to drive indoors, and provides a smooth feel similar to driving on the highway. However, some fluid trainer models tend to leak, so it’s important to research different models before purchasing. Avoid fluid trainers that use water as resistance; find one that uses silicone instead.
Magnetic trainers are the next best thing, and they are more affordable than fluid resistance training units. These units tend to be a bit stronger, and the ride quality isn’t quite as good as a fluid trainer, but a mag trainer will still provide strong resistance that can often be easily adjusted using an adjuster on the unit or using a resistance mounted on the handlebar lever. The adjustability isn’t as precise as a fluid trainer, unfortunately, but it is more adjustable than a wind trainer.
Wind trainers are the least likely to break down, but they are also the loudest and least impressive when it comes to ride quality. This type is best for the beginning cyclist or a cyclist who is on a tight budget when it comes to purchasing such a unit.
