Many individuals feel like there's a big difference in torque vs rpm assist, so maybe I'm insensitive. My battery is capable (at five years old) of powering the rides which don't exceed about 15 miles and 3,000' of climbing; there's always at least 30% remaining (based on voltage measurement; probably not extremely accurate). Doesn't bother me either way since the bike(s) can be pedaled without the "e" power, but hasn't been necessary. So much depends on weight, wind, how much pedaling you do, hills, how fast you want to go ....... that it's very difficult to predict range for an individual. My guess is that you could complete your commute with 52V, 10 ah.
