Horizon Fitness employs a magnetic resistance system. It is a friction less system which means that there are no internal parts that make contact with the flywheel. The second reason that this machine is so quiet is that they exclusively use Poly V drive belts instead of chains. Not only are poly V belts super strong and reliable, they are virtually maintenance free. There is very little maintenance that you will need to do to your machine once you assemble it in your home.
Basic maintenance includes wiping the machine down after each workout to remove the sweat.
All of the internal bearings are maintenance free and the belt should never need tightening. Belts are now used in far more demanding applications such as motorcycle drives for example. Horizon Fitness has tried to do as much assembly as possible at the factory. However, for transport purposes you will have to do minimal assembly to the machines once you get it home. Our studies have shown that it takes an average of 30 to 45 minutes to assemble any of the Horizon machines.
