I have to admit that this weather is prob my fault: I ordered a (recumbent, delta) trike last week, principally as a poor weather commuting tool. Every commute since the order went in has been sub-zero & a little bit challenging. Coincidence?
So I predict a warm, dry Jan...
My understanding is that they are a lot easier in ice & the other advantage is that they're harder to come off (I've already had 3 weeks off bike this winter after a sub-zero slip & injury).
Looking forward to drifting around corners on 3 wheels, since it's a teensy bit frightening to have back wheel drift when you're on 2 wheels.
