How the iBike Works

Delivering power measurement at a fraction of the cost

Power measurement is really about the measurement of force: Power = Force x Bike Speed

Cyclists apply forces to bike pedals in order to overcome the forces resisting forward motion (hill climbs, wind resistance, rolling resistance, acceleration, etc.).

Traditional power meters measure the forces applied by the cyclist. The iBike is the only power meter that measures the opposing forces that resist the cyclist’s forward motion.

According to Newton's Third Law,
applied and opposing forces must be EXACTLY equal.

How the iBike Cycling Power Meter Works

So, by measuring the opposing forces the iBike gets the same answer as traditional power meters,
but with less weight, cost, complexity, and more simplicity and flexibility.

It's important to note that iBike power meters MEASURE power. They don't estimate it or calculate it -- they use the principles of fNewton's Third Law and state-of-the art sensors and tools to measure power.

Just how accurate are iBike power meters?

Boyd Johnson, CAT 1 professional cyclist and cycling coach was asked by wattage forum members to independently test the iBike and let them know.

Boyd's Feedback

At the request of members of a wattage forum, I did this ride with a Power Tap, iAero, and the new Quarq Cinqo. As you can see from the graphs, all three tracked each other very nicely and the comparable accuracy of all three units makes it hard to distinguish any one power meter from the others.

I have been racing all year with the iPro and the iAero. The accuracy and precision of the units makes me confident that I can trust the numbers I am seeing on the screen. The light weight and portability is also great for riders on a racing scene. Seeing power numbers in a race has always been great, but many riders don’t want to add the weight of a traditional power meter. With the iBike, you certainly don’t have to worry about the data slowing you down. Thanks to the benefits of power training with an iAero, I had my most successful season ever as a racer!
