The Bullit is max power at 85Nm vs the Rise at 60Nm, correct? If your puling 85Nm on the Bullit compared to 60Nm on the Rise, that would make some sense that they were fairly close on range. I assume the Bullit felt like it had a lot more assist than the Rise, correct? Either way, that's a pretty impressive result. With both using max power there was only 15% more range for the Bullit that has about 75% more battery capacity. I guess the other variable is, did you ride at the same speed on both runs, ie. was your input more or less with one bike vs the other which would use more or less motor power and battery capacity. No real way to measure that I assume, still, Orbea did it well with battery management. Too many variable to really do a true comparison...but who cares. I love my Rise and have gobs of fun riding it.
OK, nest test: Set your Bullit at max power of 60Nm with the app and then run the same test. Then after that, ride the same trail backwards to see if the reuslts are the same then do the same test over again making sure you're riding in the exact same gear with each bike on each section as well as use a wind gauge to make sure there is no difference in wind assist difference.
