I think the reviewer just didn't manage his power like an owner with more experience would have. This Sunday I rode from Pacifica (located a few miles south of SF) to Alice's, charged up with my 900 watt charger for 2 hours and returned via Highway 84 to the coast highway and home along Highway 1. The distance was 78 miles and when I returned home I still had 4 bars on the fuel gauge. But I was able to do this by staying off Interstate 280 and riding along its frontage roads instead. I also followed some Harley baggers down Highway 84 to the coast and that also helped to keep my speed low. Coming up the coast I was keeping to the 55 mph speed limit.
I think electric motorcycle testers need to not pay so much attention to the manufacturer's advertizing department's hype and more attention to riding smoothly, with an eye to reducing power consumption - if their intent to to go for a long ride and return home without running out of juice. As I have said before, replacing the 2012's second speedometer, or the 2013's rev counter, with a power (amp) meter would help the rider learn to manage battery power.
In my opinion, I think the Wired tester could have accomplished his entire ride to Alice's Restaurant and back to SF if he had stayed off the freeway, picked his route carefully, rode smoothly and just charged at Alice's while he was eating there. But riding like that might not be as much fun for some people as it is for me. (I like to stay off the "beaten path".)
