There may be some glitches that might produce erroneous readings here and there, but when averaged out, the power data appears to be as meaningful as what you get from a PT.
The
average power over a ride is not particularly meaningful. Before I got my Quarq I was trying out the power track plugin for SportTracks. After I got the Quarq, I ran the plugin on some rides with real power data to see how close it was to reality. I found that the averages were actually pretty good, but the details were off. The useful training information is in the details.

That only applies when paired with a real power meter.

The iBike looks good on paper. It doesn't seem to hold up to reality. Real-world, long-term use.
