Does anyone with an aerodynamics background know more about the holes in the frame? How do you think about whether this frame on the bike is better for aerodyn

  Wouldn't the big human on top of it be the worst part of its aerodynamics?

    That's a given in either case, though.

  > whether this frame on the bike is better for aerodynamics than a more continuous but wider surface It's certainly worse but I don't think drag is a driving design consideration for this bike. Those holes undoubtedly there to reduce material/weight...

  It would be a pretty simple exercise to develop very lightweight fairings for this frame. Clearly it wasn't a consideration in this proof-of-concept design, so it doesn't make sense to consider this as anything more than a sign as to where things are going. It looks like they used topological optimization with some set of load cases analyzed through typical Finite Element Analysis codes. If they had wanted to, they could also have factored in aerodynamics in their optimization procedure, with either a shell type of approach if they wanted to make the whole thing 3D-printed metal, or with a separate fairing.
