I’ve been considering upgrading to a HPR60 motor in my ex-e because, well, I’m kind of an idiot and like blowing good money on stupid sh*t when it comes to bikes. I don’t care at all about the increased power of the HPR60, and realize that it would still be capped by firmware at 300W in the ex-e anyways. But what appeals to me is the claimed increase in efficiency (reportedly between 15% and 20% less battery drain by some users) and the even quieter motor noise… y’know, to pair with those Onyx hubs I love so much. An added bonus would be to keep my HPR50 on hand as a spare that can be swapped in relatively quickly if I do have a motor failure, rather than waiting weeks for diagnostics, warranty procedures, shipping, etc.
What I haven’t been able to figure out is whether the claimed efficiency increase is in the new motor hardware/firmware itself and would still be realized with the 360Wh battery? Or is it mostly due to more efficient energy discharge from the 21700 cells in the newer 580Wh batteries (as opposed to the 18650s in the 360Wh)? Will I actually see noticeably better battery life with the HPR60? Even a 10% to 15% increase in efficiency would go a long ways in alleviating range anxiety.
Also, what is the real world effect of increasing the torque from 50Nm to 60Nm, given that I already have my maximum power level set to 225W through the TQ app? Does that just mean that the time the motor would take to reach 225W would be less, all other factors being equal? Would I even notice a difference, as I also like to keep the engagement speed set quite low so I don’t ever really feel the motor cut in or out while riding.
