I don't bike. But, I've quite a bit of experience hiking.
This camp really sucks. But, it sucks so bad I can't tell if the OP needs UL camping guidance or is so experienced they knew exactly what they can do poorly in this situation and be fine.
Here's a couple things, I guess: Your back is cold in the hammock because an insulation layer belongs there. You'll wake up wet in the tent because you're sleeping in contact with the tent (looks like solved with a couple branches)
The bike goes inside the tent so it doesn't get stolen?
I've never seen a tent made for this. My plan would be to fabricate a custom shaped tarp from silnylon (like, way easier than it sounds). I'd try to forego the pole(s) by tensioning over the bike. This would need a few structural reinforcements and it'll leak at all bike contact points.
The advantages of a custom tarp would be that it's medium cost, exactly what I want, and it'll only weigh about 1.5lb including rigging. A slightly modified Chinese knockoff, such as a Lanshan 2, could probably be repurposed for about the same cost and a lot less effort.
We hikers love our kit just as much as you bikers. It's our favorite subject. Come steal all the good ideas.
I think MSR makes (or made) a tent with a bicycle garage, velo tent, with a big vestibule.
Why anybody needs that i have no idea, but you see people asking for this kind of tent every now and then. I guess so they can actually sleep and not lay awake worrying about bike thieves who sneak through the woods at night ;)
Yeah. If this was the only way to set up my tent then I'd have gone without it. It's creating worse problems that it solves. Even being on the correct side of the wall in the background is more cover.
But, I don't want to be a dick and not state the positives. The OP is learning in peak summer. They probably won't suffer much more than a cold night. And, they've a bike that greatly increases chances of success if seeking the safety of civilization. This is a significantly safer way to learn than what I did.
