You're probably in the right forum. I can't think of anything more appropriate, anyway.

I'm not familiar with either of those models. But I'm willing to guess that I would not ride them down any stairs.

Other than that they're probably capable of taking mild off-road use by someone who is not particularly heavy. We'd better add "at moderate speed".

This isn't a very specific answer, is it? Sorry, but I don't have specifics.

But don't ride them like a mountain bike. They probably can't take that.
