Your MagneTrainer can interact with dozens of driving and racing games using the MagneTrainer PC interface.
Your pedal motion controls the speed of your vehicle.
The faster you pedal, the faster you go.
Here's a list of 67 driving games that you can try out for Free.
You can use your keyboard, or a game controller to steer with. If the software supports it you could even use a USB steering wheel.
Some games like Need For Speed Carbon« (above) have a Nitrous button that will make your car go faster. The PC Interface can press this button for you when you exceed a certain pedal speed.
"I am immensely pleased with both the build quality and the resistance. This will provide good solid exercise when couch-bound. Great for those of us who don't like to go out in the cold and/or have small apartments."
