A pothole is not going to effect this wheel anymore than a normal wheel is effected. If you look closely at the first and second picture you can see the spokes traversing the rim, which means this new wheel is exactly the same as the old wheel. It just doesn’t have a gear sprocket in the middle of it.

I’m not so sure. It was my belief that the spokes added mechanical strength to the wheel to so as to endure most obstacles on the road without falling out. The wheel here is narrow and the gear mechanism seems flimsy. So it might be easier to dislodge. Only testing it will tell.
