Had an interesting quirk this morning. I was riding along at about 26km/hr when the Bolt suddenly paused and immediately turned back on again. I was passing under a tree so put it down to interupted satelite signals though I use that route every day without previous drama. Lots of trees on that route so it was possibly a cumulative thing. As the ride progressed, now out in the open, I noticed that even when riding three or four km/hr above the shown average, the indicator showed that my ave speed was decreasing (though the number shown wasn't winding back). Finally, my maximum speed was 1,567 km/hr - I'm not even that fast in my dreams.
And interestingly, the numbers uploaded to rwgps are different again.
I'm hoping it's a one off. Anyone else seen something similar? I'm guessing we can't expect perfect satelite connection all the time.
