Actually, if you look at the geometry, VN isn’t really significantly different than most other flat bar bikes. I mean, if you’re coming from a drop bar bike you have to understand that top tube lengths are gonna be longer for same size bikes. That’s not a novelty, it’s just basic bike geo.
Check out the
Kona Dr Dew. It’s damned near identical, save a few mm here or there. Nobody’s claiming Kona’s bike geo is odd or unusual. The only thing that’s remotely different is that both VN and Kona use older, more traditional nomenclature by stating sizes based on seat tube lengths. Nobody really does that anymore, but that doesn’t make VN or Kona wrong about it.
Vegan makes a point in that it’s easy to blame the shop and we’re only getting half of the story, but unless OP demanded the wrong size against the shops advice (and that’s a possibility here) then this one is on the shop. Flat bar geometry isn’t a novelty and it damned sure isn’t rocket surgery.
