The Wahoo KICKR Headwind keeps you fresh during your indoor training. By connecting the headwind to your Wahoo heart rate monitor, speed sensor or bike trainer, you can have the airflow automatically adjust to the intensity of your workout. The harder you cycle, the harder the airflow is out of the headwind. This airflow is optimised for someone in a bicycle position and can reach up to 48 km/h. So you can stay cool during the training on your bike trainer. That way, you might be able to give just a bit extra. In addition to its automatic function, the Wahoo KICKR Headwind can also be manually operated and adjusted. This gives you the choice of 4 different modes. These modes can also be modified via your Wahoo App.
