using power tap technology, the cycleops bikes are a cut above the rest.
No cheating here, the freewheel acts as it would on a bike outside and your pedal stroke has no assist. Numbers are collected, can be downloaded. Improvements are readily seen in the 5 sec, 5 min and 20 min peak power. $650 More efficient than putting a power meter on your road bike!
