Marks
Eddy current resistance system The T4r features a speed dependent eddy current
resistance system that is dependent on workload level
selected, the user step rate and the user step length.
Range
5 - 800 watts
Stepping Action The T4r features dependent stepping action with
2”–8.5” (5-22 cm) stepping range.
Watts Testing Parameters Displayed watt values represent the energy
consumption rate of the user. They are calculated in
real-time utilizing an algorithm based on mechanical
parameters of the machine and a measured average
ride style. The signifi cant mechanical parameters
that infl uence the displayed watt values include the
inertia of the machine’s moving components, the load
level selected by the user, and the rotational velocity
of the eddy current disk. Validation testing of the
displayed watt values was performed by comparing
said value and the actual measured mechanical power
produced by multiple users. Displayed watt values
are independent of any physiological or anatomical
parameter possessed by the user.
