0on our e tandem we use very little power when we cruise at 18.5 to 19mph the motors cutoff curve is right there. the prime is we could go faster on the flats but cadence is wrong we would need to go 22mph to get the cadence in the 80 range and we can't quite manage that. 19.5 is like 75 rpms and its too slow.
this ride we did not use much motor till coming back and we hit some 15% grades. no way we could do that all on our own. its hard to get a higher heart rate on the tandem unless we climb constantly but this is not too bad for a mostly flat ride.
