Done 400 km on kicker, no problems. During race wattage went extremely high then faded to zero .Resumed , happened again about six times then back to zero. Restarted everything again . Now unable to move, zero watts.
Got the same thing happening to me. After around 30 minutes the KickR starts to lock up and release. Watts jump to 8W/KG then 0W/KG. This is continual not just 5 or 6 times.
Did you resolve your issue?
Yes fixed the problem, sunlight was effecting blue tooth . Placed a bit of tape over blue sensor and closed the blinds. Been working fine since then
