10,000 measurements per second
In order to do this accurately, we adjust the resistance 1000 times per second, and we take measurements of you and your TrueBike or TrueTrainer close to 10,000 times per second. That is simple math done very quickly by our robot.
Also, since your pedal push is strongest when you move the slowest, we don’t rely on electro-magnetic (also called Eddy current, used in most higher-end indoor trainers), fluid (viscous) or wind forces to guide your pedals. We use a very strong motor in our robot, straight out of a car. Since we labelled this section the science section we will show you in a graph. As you can see, a motor can deliver a force, even at standstill (also known as the holding torque). This is how cranes and elevators work. They can hold your weight like we can hold your pedal force, even at low speeds.
That gives you the unique sensation when standing up and riding up a hill: Your pedals hold your weight and you don’t fall through! But … there is a limit here. Due to safety and wear considerations, you can go down to about 30 rpm and below that even our motor gets a bit sloppy with its placement accuracy (normal cycling is between 80-100 rpm).
