I was very skeptical at spending this kind of money on a fan. In my setup before this, I would run a ceiling fan as well as an oscillating fan locked and pointed at me about 6 feet away. I thought this was adequate and didn't realize how inadequate it was until I started using the Headwind.
The Headwind can be controlled 3 ways. You can use the Wahoo Fitness app on your phone/tablet to control it manually, you can use a heart rate monitor paired to the fan to control it based on heart rate, or you can pair it with a compatible Wahoo Kickr trainer and have the trainer control the fan speed based on bike speed.
Controlling it from the app is quite easy. The app was able to see the Headwind immediately and controlling it is done with slider.
My Wahoo Kickr trainer is an older one so is not able to control the Headwind. But I don't think this would be useful since I'm not concerned about realistic wind as I'm riding my trainer. I'm concerned about keeping cool. For example, if I'm only riding 5mph but up a 12% grade, I'm putting out a lot of power to keep moving ahead so a 5mph breeze won't do much to keep me cool.
I found that controlling the fan speed with my heart rate was the most desirable solution. Pairing is pretty easy and in the manual on how to do it so I won't go into that here. Once paired, I can go into the Wahoo Fitness app and set the range that it will operate within. I have mine set to come on at 95 BPM and be at max speed at 155 BPM. My max HR is 178 BPM so this is a bit below that.
I've been using the headwind for about a week now. I have it about 5 feet in front of my bike so that I feel the air on my chest and face. At full speed, this puts out a lot of air! Much more than my ceiling or other fan could provide. And with it being paired to my HRM, I just put on the strap and the fan will automatically turn on when it sees the heart rate. Can't get any easier than that! So as I start the ride, the fan will blow very little but as I exert a lot more energy and my heart rate climbs, the fan speed climbs with it. I've seen reports that people with desks (which I don't have) in front of their bikes will have the air blocked and may need to locate the Kickr off to the side rather than in front of them.
Overall I'm very happy with this purchase. It's a lot of money and I hope it holds up over time. Assuming it will, this is a great purchase and great addition to my Pain Cave.
The KICKR HEADWIND is the first ever smart fan, designed with the cyclist in mind. Its Targeted Airflow Pattern mirrors the shape and position of a cyclist's body while riding. The KICKR HEADWIND is sensor controlled so as your speed or heart rate increases, so will the fan speed, and there are also 4 manual speed settings should you want to set your own ideal airflow. With speeds of over 30 mph (48 kph), the KICKR HEADWIND will keep you cool during the toughest training sessions.
