Did in fact get the brakes sorted. The front rotor is not true, but it was that way out of the box, I now realize. Not a huge deal.
Tonight I had to wait until a small shower passed and then I went out. Along the trail, the same one I rode the other times, the bike felt a bit draggy. At not quite the furthest point from home, I realized why -- the battery died. I had to ride home about a mile and a half with a dead battery 50 pound bike. Fortunately, it is relatively flat here.
I have to say that for a guy that supposedly has a heart condition, it wasn't that bad. I figure that between the weight of the bike and me I was probably pushing as many watts as Roglic today. OK, maybe not. But other than really needing a shower arriving home, I was OK.
