i’ve never seen snow in real life.
and i’m glad.
What the article writer is missing, is that unicycles are actually a brilliant way of getting around in snow - maximum traction, easy to take on public transport if it is running, easy to walk with through deep snow, and doubles up as a makeshift ice axe if the worst comes to the worst on a steep slope.

Just what I was thinking. I would much prefer to ride my unicycle in the snow than my bike. I went riding with a friend last night, I was doing 180s and 360s in the snow but my friend was scared to even pedal his bmx for fear of slipping over!
EDIT: I recognise that guy, can’t remember his name though!
Haha, I like how Joe’s excellent comment on the website is several times longer than the paltry ‘article’.
It’s a small shame that he’s photographed on the pavement though, as that’s not really advisable or legal (isn’t a unicycle is legally a bike in the UK?), and often worries people, with or without good reason. But it’s snow time though, so normal rules often don’t seem to apply 
I’ve recently moved to London but not taken a unicycle outside yet. Biking in the traffic is fun though.

I think it’s probably Jamie Ashdown-Parkes (sorry if I got the name wrong), who posts here as jap.
If it is him, that’s good because I haven’t heard from him since he pulled out of the Exmoor Explorer race a few months ago with an injured knee - glad to see you’re riding again Jamie (if indeed it is you!)

Similarly, somebody seems to have taken a picture of me this morning for the BBC local news

Not much snow here at the moment, but too icy for my liking on a bike - muni is the commuting vehicle of choice.
