How Do I Calibrate the Bushido Smart Trainer?
Measurement of performance data on an indoor trainer is important. All Tacx® smart trainers are measuring speed, cadence and power. In order to have an accurate power measurement the trainer needs to be calibrated. This is done by a simple and quick spin down calibration process. It is also important to update the software on the trainer to ensure accurate power measurement.
The spin down calibration process can be triggered from the Tacx Training™ app. The application will guide you through all the steps.
NOTE: A trainer tire is highly recommended. Make sure the rear tire is inflated to the max pressure recommendation printed on the tire before proceeding (Ex: road tire max pressure ranges from 101-116 psi).
Calibration Process
NOTE: Use the trainer on a firm, level surface. If on carpet, use a mat.
Download and install the Tacx Training app.
If the app is already installed, be sure it is using the latest update.
Open the app and select the Settings icon.
Select Device Manager.
Select the Tacx Bushido from the list of trainers.
When all icons turn green it has been connected successfully.
Select Set Up Tacx Bushido.
Select Calibrate.
Select Calibrate Now.
Follow the app on-screen instructions.
Start pedaling and accelerate to 18.6 mph.
Once the speed reaches 18.6 mph.
Stop pedaling and let the wheel come to a complete stop.
Upon successful calibration, observe a green checkmark and the message "Your Trainer is Calibrated".
Select Finish.
Select the back arrows until you reach the Dashboard of the Tacx Training app to select a movie or workout.
Why Is Calibration Required?
There are many factors (E.g.: room temperature, tire pressure, rolling resistance, etc.) influencing the power measurement. With a calibration, all these factors are measured and calculated to a single calibration value. The value is being used as a coefficient to calculate the power input of the cyclist.
How Often Should I Calibrate?
Perform a calibration after any of the following changes.
Tire pressure changes
Pressure of roller against the tire changes
Temperature of the environment significantly changes
Tire is replaced
How Can I Avoid or Reduce Tire Wear?
To avoid or reduce tire wear, check the following:
Ensure that the calibration arrow is lined up in the center of the green bar after calibrating in the Tacx Training app.
Tire pressure needs to be very high on a trainer tire. (see the max it needs to be on, printed on the side of the tire)
Clean the tire and roller. (use white spirit to clean the tire)
If the tire is older than 1 year it may be dried out.
