kMeter

The Exxentric kMeter is our wireless science-based feedback system for flywheel training.

The kMeter system is developed specifically to accurately monitor power and energy as well as estimate force during strength training on the kBox. It is used by coaches and physiotherapists as well as directly by athletes and patients.

The system measures the rotation of the flywheel with high accuracy and transmits the data to a smartphone app with a simple and accessible interface to present key training results, including:

  • Concentric and eccentric power
  • Range of motion
  • Force
  • Eccentric overload
  • Energy expenditure

The kMeter system consists of two parts: the kMeter II, or earlier model kMeter Module,  installed on the kBox, and a free to download app:

kMeter App

The kMeter App can be downloaded for free and installed by every user of a kBox equipped with the kMeter. Users can monitor the results directly on his or her mobile device and are able to save, browse, share or even export to excel for analysis.

kMeter hardware

The only thing you need beyond the app is the kMeter II itself and it is since May 2018 pre-installed on all kBox4 Lite and Pro units and the kPulley. kBox4 Active is kMeter-ready and you can either buy it with your kMeter installed or buy it afterwards and mount it yourself in a few minuts. The kMeter device registers rotational data and sends it via Bluetooth to your mobile device or pad. It is battery powered for complete mobility and always on for ease of use. It can be connected to an unlimited number of mobile devices, so each user of a kBox can keep track of their own development.

The latest version of the kMeter stands out for its remarkable ability to sample data up to rotational speeds of 155 revolutions per second. It has a sample rate of 10000 Hz and it receives 64 impulses per revolution of the flywheel.

Earlier models of the kBox have a rotational sensor pre-installed and connect to the previous model, the kMeter Module. It is easily connected via a connector and it is also battery powered.
