kPulley Go, Jet Black

Select from the dropdown menu or click on the link directly above

The kMeter for the kPulley Go has undergone a small but important design change since its launch to ensure its robustness. So unless you’re purchasing this feedback module together with a brand new kPulley Go, please use the optional message field at checkout to specify the serial number of your kPulley Go to help ensure that we send you the right kMeter.
 

Please remember to verify whether your kBox is equipped with a magnetic (choose kBox Active, Jet Black) or rubber sensor (choose kBox Active, Other) prior to placing an order by safely flipping your kBox over and inspecting underneath the shaft cover.

kBox Active, Jet Black

Select from the dropdown menu or click on the link directly above

The latest kBox version of the kMeter detects flywheel rotations through a magnetic sensor, which can be found on all Jet Black kBox Actives (including jet black legacy models from 2023-24).

Whereas the previous iteration of the kMeter collects accurate measurements through a rubber sensor disc with spikes, which can be found on all other no longer available legacy platforms (Desert Bronze, Carbon Black, Arctic Blue, Frosty Green).

Again please remember to verify whether your kBox is equipped with a magnetic or rubber sensor prior to placing an order by safely flipping your kBox over and inspecting underneath the shaft cover.

Specifications

The system measures flywheel rotations wirelessly with high accuracy at rotational speeds of 155 revolutions per second and at a sample rate of 10000 Hz it receives 64 impulses per revolution. This all gets processed in real-time into 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 wireless transmitter connected to the flywheel training device and its corresponding app.

Exxentric App

The Exxentric App can be downloaded for free and installed by every user of a LegExx, LegFlexx, kPulley or kBox equipped with the kMeter hardware. Users can monitor the results directly on their mobile devices and are able to save, browse, share or even export for analysis.
