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

This particular hardware is built-in to all Legacy models, which measure flywheel rotations with the help of a rubber sensor disc, as opposed to the magnetic ones used in the latest generation of equipment.

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

This is a standard component included in any new kBox system, making your flywheel training even more effective by creating a better setup for more horizontal movements such as bent over rows and swings.

The Exxentric Flywheels are an indispensable part of the kBox4, kPulley and SingleExx series of flywheel training devices. They are made from laser cut, balanced and powder coated carbon steel.

The number and size of the flywheels used determine the inertia of the flywheel training experience. The color coded option makes it easier to distinguish between the inertia levels of each flywheel.
