I have gone to the Sea Otter Classic bike festival in Monterey CA every year since 2008 and last year had the most ebike booths. I tried out one and it was really fun, but expensive. I think the price of those bikes may exclude many people from purchasing them.

There are neoprene face warmers for skiing/snowboarding if your face gets cold. I've used one before when I was a skier and they work well. (I snowboard a few days a year now).
