bschloop, Did you build a velomobiles with the thought of selling them? If so check out velosRus.com aka Carolina on recumbents.com as he is making velomobiles uni-bodies.
I guess also that's not a cut and dry answer. Rider weight/bulk and other factors could also play into whether a 125 could make the ride w/o getting passed. The one time I rode, I felt like if one can get up and stay up near the front, the better off he or she is with respect to not having the sling shot effect, but everyone can't be in the front.

Wow bschlop. Is this a fully streamlined machine you're going to show up on?
