I've played a bit with Dacron covered ultralights (owned a Quicksilver MX) & while it's good stuff, you're perhaps familiar with industrial shrink wrap products such as these:

I've used it rather a lot in the marine industry, not that particular retailer (example) but it's the same group of products, including tape, zippers & even louvered vents. Light, durable, strong, easily repairable & best of all cheap, it does require at least a light framework & isn't puncture resistant, ofc.

I've also had some experience with geodesic airolite boats similar to these: while those do use Dacron: the shrink wrap is far easier & cheaper to play with, the ultralight boat's internal hull structure plausible as a basis for a velo, with a nice slippery shape;

Being that an areoshell isn't load bearing, it could be constructed out of little more then 1/8" ply stringers, gussets & epoxy - the entire structure likely requiring no more then a 1/2 sheet of ply & a 12'x8' bit of wrap & a chunk of clear plexi ofc... if one had access to cut offs, it'd be a $20 to $40 project or thereabouts, time not included lol
