The world’s most popular power meter: the G3 hub by PowerTap


In 2005 PowerTap introduced the world’s first-ever wireless power meter – and they’ve been striving to improve upon it ever since. Enter the G3, the third generation of hub-based power meters.

The G3’s design allows for a simple, straight-forward way to measure power. By mounting the strain gauges in an area where external forces, such as spoken tension, cannot impact power measurement, the PowerTap G3 is able to deliver +/- 1.5% accuracy ride after ride. More than just a power meter, The G3 delivers speed, cadence and power with pin-point accuracy all in one product. And its ability to be easily switched between bikes means you’ll never miss a watt.

Operating Mode G3
On a bicycle, there are three places to measure power: the hub, pedals or crank. Power is measured as the amount of force or torque generated at these points of measurement (pedals, crank or hub) multiplied by the speed or angular velocity of the pedals, crank or hub. So power output on a bicycle is simply a product of how hard you push on the pedals and how fast you are pedalling. To produce more power, you can either push harder or pedal faster.
PowerTap’s hub-based power meters work by measuring the amount of force, or torque, at the rear hub using strain gauges embedded within the hub. The PowerTap hub also measures the speed of the hub by using a speed sensor within the hub and a magnet attached to the axle.
