Wahoo KICKR Smart Bike Trainer - Brand: wahoo - Model Name: KICKR - Features: Smart Bike Trainer Thank you for viewing. I received this from an acquaintance, intending to use it because it's cold, but although I could confirm the connection with the Wahoo app, I couldn't calibrate it properly. Bluetooth connection worked, and when I increased the resistance percentage in the app, it became heavier, so I think something is wrong with the electrical components. I recommend this to those who can fix it or are knowledgeable. This is considered junk, so please understand that it is non-refundable and non-returnable.
