I haven't taken mine out in the snow yet, but just from my experience with tires, I think it would do awesome. The tires are air of course, and large in diameter. That will help navigate over the rough snow terrain.
The Chariot also comes with an adjustable suspension that you adjust to your kids weight. That helps absorbs bumps and such.
Since Chariot is from Canada there are several members here with Chariots that could probably answer your question more about the snow and ice.
I can tell you though that is a weather resistant, and see that rolled up clear shade on the top of mine? That comes down, and then the kids are water-proof, and weather proof. Throw some blankets in there, and they get pretty toasty. Of course, I don't live in Canada, but this morning when I put the kids on the school bus it was -4 F
I have no issues taking the kids out in the cold in the Chariot, knowing they will be protected. It's my lungs that can't handle it
So hopefully some Canadians will chime in. I know member Jewels has one. It's actually this forum that talked me into getting a Chariot. They are very very high quality, and you do get what you pay for. I'm sure my resale value will be quite high as well
Oh, and I just snapped these photos as well. This is how we store it. It folds up quite nicely
We just made a simple bracket for it, and hang it on the wall in the garage.
