Hey Rob, can you comment on the quick swap removable battery pack lengths, and their placement in the PR model? I see the removable 800wh battery is kind of heavy relative to it's internal counterpart, but I was curious if it's length or placement lower down may actually give the front end a lighter feel than the 800wh integrated battery. Similarly, the 600wh removable battery is actually quite light, and I'd wondered if the PR model with a 600wh battery swapped in could be a pretty sweet setup for shorter rides, or is the mass still located up by the headtube?
I'm just thinking that if the weight distribution is the same or better with a PR, then a hot setup might be to have a 600wh and 800wh, so you could choose the appropriate capacity for a given ride, OR swap them for long days spent lapping a given trail center, OR stack them using the 600 as a range extender for the occasional backcountry epic (even if it is a sort of clumsy looking setup).
