When calculating the brake resistance, all physical formulas a cyclist encounters on the road are applied, in order to create a situation that is as realistic as possible. Air and rolling resistance, gradient percentage, weight, air pressure, wind speed, temperature, altitude, inertia and brake properties are all taken into account and calculated hundreds of times per second to achieve a realistic feel.
A virtual flywheel dynamically controls the brake force. This means that the resistance is calculated and adjusted continually to simulate natural road resistance. Whereas other trainers use a flywheel to pass the dead centre, the Tacx IRONMAN uses calculations to predict the movements of the bike and simulate the action of a flywheel. The Tacx IRONMAN even has a downhill drive. The wheel keeps turning, so you do not need to pedal, just like in real life. The virtual flywheel can generate a variable inertia effect, allowing it to simulate the bike movements of all cyclists up to a specific bodyweight (125 kg max.) in a highly accurate manner.
With our software and apps, you may regulate your training ride by heart rate, gradient and power, or you may pick a famous route or race. Besides that, you may compete with other riders online. The training options vary by application.
All of our trainers are freely accessible since June 2015 as they are able to speak the ANT+ FE-C language. You can now adjust the resistance of our Smart trainers and check your speed, cadence and power with other software. The following software packages speak this new language too and allow you to control our trainers:
