got everything going good

did u leave in the dust cover did it have one if it does did u have to trim it? i would say every 100 miles i put a grease fitting on the hub so i could use a grease gun

full-time power and more speed, as opposed to pedaling and coasting at lower speeds has been a bit harder on my rear wheel bearings... they were probably not the best when I powered the bike, but the rear wheel loosened up after a couple hundred miles enough that I noticed it.
I'd give the wheel a sideways check for play on a periodic basis. YMWV depending on how you ride.
...a while back another rider mentioned he's wore out two back wheels, but no front wheels...

Best
