Overview
e-Bikes are great for extending your range, using less energy, or doing bigger climbs. They're also heavier, less nimble, more likely to run down or malfunction, and more likely to get stolen.
It's pretty flat where I live. For anything under 5 miles, I just take a normal bike. If I'm not in a hurry and it's under 10 miles, I take a normal bike. Over 25 miles, I take the e-bike. That leaves a pretty wide range where their ideal missions overlap.
Six Week Update: I have had the e-bike for 6 weeks now. Since the range test 5.5 weeks ago (more info below), I have ridden the e-bike once. In the same time, I have put over 500 miles on my human-powered bikes. The night-time low here in Phoenix has averaged about 85, and the daytime high has averaged about 105, during that time.

Range Test One
41 miles, 15 MPH, mostly flat, moderate pedaling. At that point I was at 46.8 volts and the voltage was falling fairly quickly.
The 48 Volt, 13 Amp battery is wired 13x5 cells, so the lower voltage limit is 46.5 volts. Below that you're risking damaging the batteries. The voltage is dropping so fast at that point that you would only get a few more miles out of it if you did go into deep discharge.
