Took it for another spin today, I have to say my choice of the 26X1.95 Tioga City Slickers was well made, they handle the weight well and there's less rolling resistance. Replaced the faulty link in the chain and it worked like a champ. I'd say it's a pretty efficient setup.
I've been scouting bike routes out of the city, and it appears I also struck paydirt there as well (after a lot of riding). I only hit one pothole and had to reseat the panniers only once. Of course, it was a bit of a problem staying to the speed limit on the bike trails, so I've decided to stay off them and stay on the road. I'm still pretty cautious, but the drivers that use the bike-friendly routes seem to be pretty savvy.
Total usage: 13.28Ah, Distance: 39.84km (25 mi), moderate pedalling (except on the 3 major uphills, I still stayed seated) and regen rate 10.4% (1.385 aH).. I was a little worried about the LVC cutoff as I approached home - the voltage on the pack was reading pretty low. I think I'm going to have to tweak that.
This bike has really proven out.
