I had my OW in the back of the car this morning at work and I went to ride it during lunch (it's 14 deg F) However, the power button light came on but when I stood on it nothing... it just tipped front down. I tried a couple of times to turn it on/off but nothing. I guess cold weather isn't good for the OW's. This worries me a little since there's at least 6 weeks of winter left :(
