Split rims for the GT08

The way I change my tires knobby winter and fall and summer spring street tires plus even with slime the amount of random glass on the streets. And with bike shops checking $50 a tire with my tire and tube split rims is a must. So originally I had ordered a couple of those 2800w roadrunner motors that you see for sale everywhere for like $100. Happily the hadn't shipped yet. I decided to go with a 60v/72v motor that is 2500w at 60v and either 3500 or 4000 at 72v. But I don't want to switch out my 37amp controllers I like the acceleration and everything the way it is. So looking around I decided to go with 2x2500w motors instead of the 2800w ones. These once I found have 50H magnets so there definitely better then the stock and at Max at 85kmh for 60v I think with the 37amp I'll get more out of these and for $120 a piece with $36 shipping I'll save that in tire changes in a year. I can do it on solid rims just takes me like 2 to 2.5 hours a tire lol. Any opinions 2800w or 2500w? Anyone know anything about these you can read the numbers off the pics for anyone that knows I'll. I cancelled the other ones probably order these tomorrow thanks in advance happy New year
