kMeter II
The Exxentric kMeter II is our wireless science-based feedback system for flywheel training.
The certified kMeter II comes built-in with all LegExx, kPulley2, kBox4 Pro and kBox4 Lite devices since May 2018. It is also available for purchase as an add-on to the kBox4 Active.
The kMeter II system is developed specifically to accurately monitor power and energy as well as estimate force during strength training on select models in our series of Flywheel Training equipment. It is used by coaches and physiotherapists as well as directly by athletes and patients.

- Range of motion
- Force
- Eccentric overload
- Energy expenditure
The kMeter system consists of two parts: the wireless transmitter connected to the kBox and its corresponding app:
kMeter App
The kMeter App can be downloaded for free and installed by every user of a kBox equipped with the kMeter Module. 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.
