The Revbox Erg supersedes existing stationary trainers by providing athletes with a high performance training tool that has an unlimited resistance range in a compact transportable layout. Design requirements were to create a device that would allow extremely high power output training, from very low to very high cadences, suitable for even the most powerful elite athletes.
1. The fan, which forms the heart of the trainer, operates almost entirely without centrifugal mass, giving the Revbox its very low inertia. This means that the athlete does not at any point in the 360° pedal stroke receive any assistance from the weight of the flywheel, as is the case with most other trainers.
This has the major advantage that all leg muscles are utilised through the entire pedal stroke. Low inertia training can best be described as riding uphill, or against the wind, where high inertia training can be compared to riding downhill or with the wind at your back.
2. The entire pedal stroke becomes audible through the sound of the fan, enabling the athlete to achieve an even and smooth pedalling motion. If the athlete succeeds in generating a sound from the Revbox that is even and constant throughout the pedal stroke, they can be sure that they are training all muscles equally. This is an invaluable advantage that no other trainer on the market can rival.
