OK, I have about 3 hours of riding on the board at this point. I would say it is, indeed, good for 15 miles on a charge (at least).
I have had two problems. One is the seriously tiny set screws the motor pulleys use. They loosened up a couple times. So, I added a second set screw to each pulley and those are far larger than the stock set screws. Problem solved. Second problem I mention in my motor sync thread (not a big deal). Anyway, other than that, I have been riding this thing HARD! I am quite used to the power at this point. However, it still feels best set at 85%. 100% is just too much kick. I logged a maximum of 4,100 watts,according to the logger.
I had one minor radio glitch that was, shall we say EXCITING! I was running full throttle (around 25 or 26mph) when the brake spontaneously activated for a split second. That slight braking made my body react with rearward lean, then the throttle came back on and I almost fell off backward...... I have to tell you, I have a hard time imagining a wheeled vehicle that is more hazardous at such a low speed than this thing.
I love it!
