What's up with so many people wanting to know about riding scooters year-round, or in the snow? Seems there have been several inquiries along these lines in recent days, and I can't recall much of any discussion like this (other than Stig talking about his cold-weather rides and such) during the past several years.
I think it's fair to say that scooters are not really designed as an all-weather conveyance, and while you CAN ride one whenever you want to, that doesn't necessarily mean you SHOULD. Then again, I believe there is a Chinese Scooter company named Ice Bear, so maybe if you get studded tires...
