Fear not the cold/snow/icy roads...Go to the nearest snowmobile shop and get a few boxes of ice spikes used on the lake racers.
Have the tires ‘studded’ with them.
Besides, the spikes would add to the whole Cooper thing ;)
[besides...I'd still freeze for lack of “insulation”..winter for skinny people sucks]
I could always buy a Can-Am Spider 'trike' and put the skis back on.
