I bought a Kickr bike but don’t like the climb feature for the extended downhills. Normally when you are outside you have 50kph wind pushing you back into your saddle but when you are on Kickr bike you are pointing downhill with no resistance so it feels off. For uphills it is fun however the counterpoint is I can go into a low gear and just ride aero and this is better training for triathlon than sitting up for long climbs (like many of the European climbs on Rouvy like Stelvio and many more) . If I had a hill climb tri like Ironman France I would turn it back on
