Circonférence

The circumference of a bike wheel is defined as the distance around the outside of the wheel. This distance includes the additional width that a tire brings to the wheel. (The circumference is normally written on the wheel. If not, you have to measure it manually.)

To get accurate results from a Speed Sensor, input your wheel CIRCUMFERENCE only if you use
a Classic Trainer - it returns the speed, and the speed is correct only when the CIRCUMFERENCE is set correctly.

A Smart Trainer, Smart Bike, or Power Meter immediately returns Watts, and there is no need for a CIRCUMFERENCE input.

Here is how you select the circumference of your bike wheel:

• Open the ROUVY App and log in
• Click the SENSORS button in the right-top corner

• On the the CLASSIC TRAINER tile, select the ADD TRAINER button

• Select the brand and type of your trainer

• Click the WHEEL SIZE option
• Select your WHEEL SIZE
• Click the CONTINUE button 

That's it! Your wheel size is set up. All that remains is to connect the Speed Sensor and enjoy a ride.
