How well does the Kinderkraft Prime perform in regards to strolling in snow during the winter?
Well, it does have larger wheels so it can go over some for sure. There are holes between the wheel and the joint, meaning with a LOT of snow, you might nd up pulling it behind you, but this is normal with pretty much any stroller - I mean, sand and snow are two of the largest stroller enemies. So, it will perform reasonably well, though don't expect miracles.
In general, for strollers vs. snow, the "the larger wheels the better" applies.
