i-Vortex  T2170

The interactive i-Vortex has an electro brake. You can use it to train in a targeted and serious manner, even without your PC or laptop, because the i-Vortex has a handlebar computer that displays all the relevant training data at a single glance. Slope, power output or heart rate programmes are set manually during the training session. However, you can also connect the i-Vortex to your PC or laptop and use the interactive functions such as riding in virtual worlds or films of existing cycling classics and mountain stages. The route is displayed on your screen. The trainer communicates wirelessly. The i-Vortex is supplied with the Tacx Trainer software 4, Basic. It is possible to expand your training options by upgrading to the Advanced software.

The electro brake is suitable for an average training level. The gradient of the road is converted into resistance on the bike by creating a magnetic field. It can reliably simulate the road up to 7%. This brake does not simulate any descents.

The i-Vortex works with an electro brake. By placing magnets and electro magnets beside a rotating aluminium disc, eddy currents are created which generate an opposing magnetic field. In this way a non-contact, maintenance-free brake is realized that is also silent. Thanks to the electro brake a resistance can be set that you also experience on the road or in a climb.

Virtual speed
The electro brake does not have a downhill drive, such as the motor brake of the i-Genius, and it generates less power while riding uphill. When you are cycling in a virtual terrain or in a film you can get outside the range for which the brake is intended. To allow cyclists with a motor brake and cyclists with an electro brake to ride races against each other in Multiplayer, Tacx has developed the virtual speed. This concept translatesthe energy supplied into a certain speed, which can guarantee a fair contest. If this speed differs from the speed at which the rear wheel is running, the virtual speed will be shown on the screen in red.

This is a slightly simplified version of the software without some advanced features. But still there is more than enough to train in a scientific way and enjoy cycling in the virtual worlds that are so lifelike that they cannot be told apart anymore from the real world.

The Basic software is an excellent starter and makes entertainment accessible to everyone. Contains two beautifully designed Virtual Reality terrains: the Valeggio road terrain in Italy and the Velodrome. Also there is the possibility of cycling in Tacx films. This makes the trainings sessions enjoyable and adventurous. With GPS outdoor training rides can be completely relived at home. With Catalyst you can train on heart rate, power output and slope.

With Multiplayer you can compete online against real opponents. This requires a license. With the Basic software and a Multiplayer license you can ride in the VR against up to ten real opponents.
