So I went back and listened to KevCentral's review again to get those mileage claims. From the video: he did one range test at PAS 5 (full power) with full throttle only - 9 miles. He did two other range tests. Both were at PAS 5 (again, full power), with throttle off the line. The first test got 15 miles in a hilly area. The second test got 19 miles in flat terrain (he could creep 20 miles out if it, he said). Again, all his tests were at PAS 5, draining the battery at full power, which will always give you the least amount of range. These are the best numbers we have right now. As Brobox said, people are just now beginning to receive their bikes, so it will be some time before there are other hard numbers to go on. KevCentral is the best we got, and his review is pretty thorough and positive. If not having more info on the range of the bike is the dealbreaker for you, I don't know what more I can offer you. All I know is the ebike world is replete with similarly spec'ed bikes that routinely get 25-30+ miles on a charge.
