Am I missing some setting somewhere? It is like it is not using the speed sensor and the speed is being calculated through the GPS only.
bike computers fall back to the gps if the sensor isn’t reporting accurately. I’ve had this happen a number of times when the battery gets weak - it can even seem like it’s connected but the readings are flaky.
Replace the battery is the first step. Then I’d unpair it and pair it again.
