Hi!
The Britax B-Motion 4 can handle occasional travel and uneven surfaces just fine, I would say. Nevertheless, if we are talking about a very challenging terrain and super big holes and cracks on the sidewalks, don't expect a perfectly smooth ride - the stroller is equipped with only a mild-ish suspension. The front wheels are not big enough to provide a completely smooth off-road ride. Therefore, the Motion 4 is OK for everyday walks (even with uneven surfaces), but you can't expect a fantastic all-terrain performance. I do not like the center of gravity that much on this model, however, thus I will recommend to try it out before purchasing for yourself (in a shop, loaded with your child). It's harder to overcome obstacles with a stroller that doesn't fit you.
