I picked up a Velo
Solex at a yard sale, for three bucks, a few years ago. I never did ride, or even build, the bicycle, but I do recall that it felt quite light. Can't add much more than that and, perhaps offer a picture or two. That, and the fact that the VS now lives in Texas, as I recall...
As for wheels, the VS I had was not fitted with original wheels, so I can't be much help there, either.
