Tacx i-Genius Multiplayer VR indoor trainer

This interactive trainer has the most advanced resistance unit: the motor brake. In combination with the Tacx Trainer software 4, Advanced, the motor brake simulates a very accurate cycling experience. During a climb, the resistance on the rear wheel increases and during a descent the resistance unit speeds up, so it feels as if you are going downhill. The bike course is displayed on your computer screen. If you participate in online races, you’ll also see all your competitors. Communication between the resistance unit, handlebar interface and computer is completely wireless. The i-Genius Multiplayer is supplied with a 12 month license for web racing and the fold out BlackTrack steering frame to enable you to race online against your friends.

The motor brake is the most advanced resistance unit providing the most realistic cycling experience. The resistance is dynamically controlled, it is constantly calculated and adjusted in order to simulate natural road resistance, even for descents.

When calculating the brake resistance all physical formulas a cyclist encounters on the road are applied to reach a true situation. 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.

Tacx trainers feature a dynamic control of the braking force. Other trainers use a flywheel to pass the dead centre, Tacx trainers constantly adjust the resistance to simulate the most natural handling. Thanks to the dynamic braking system virtual climbs become real challenges. The i-Genius Multiplayer even has a downhill drive. The wheel keeps turning, just like in real life you do not have to pedal. This Tacx trainer best approaches reality.

LED lights
The motor brake is equipped with LED lights that move to the rhythm of your cadence. The red lights light up when the power output is high. When the power output is low, the green lights are more visible. The i-Genius Multiplayer has to be plugged into the power grid, apart from this the trainer is wireless.

Virtual flywheel
The flywheel is an essential part of the brake. By applying an arrangement with accurate sensors and advanced electronics the i-Genius Multiplayer reaches an unmatched level of reality simulation. The software-simulated flywheel of the i-Genius Multiplayer is like a virtual flywheel.

The i-Genius Multiplayer works without a cadence sensor. The cadence is derived from the variation in force on the pedals and recorded by highly accurate electronic sensors.


Tacx is a pioneer of virtual worlds for cycling and has reached a new milestone in the development of Virtual Reality. For years we have worked very hard to create unique software with which the virtual world cannot be told apart anymore from the real world. Completely new terrains have been designed, including roads with altitude differences, gradient percentages and curves. 3D buildings and trees give every terrain its own character. Lighting creates the right atmosphere and recognizable sound makes the VR world complete. The result? The Tacx Trainer software 4, overwhelming entertainment, pure cycling pleasure. You can choose from various animated terrains for mountain bike, race and track with virtual 3D riders.

The VR terrains you can enjoy lifelike interaction with riders, cars and other elements in the virtual worlds. You never know what is going to happen, just like in a real race.You can also use many films of legendary stages and cycling classics for training. With the help of geographical data and 3D maps by Google Earth outdoor training rides can be completely relived at home. And there are training programs and fitness tests for a scientific analysis of your training session.
