Lots of things to chew on here, Zero, and there's more brands on the market than I knew about, for sure.
My tentative thoughts on the subject...
First choice, I guess, is whether you want a 3- or a 4-season tent; then secondly, if you'll use it only for cycling, or for other activity as well. I don't do winter camping--not keen on -30 + wind--so my 20 - 30 years' experience has been only spring-summer-fall. Also, I use my tents for cycling, hiking, canoeing, motorcycling, and (quelle horreur!) car-camping on occasion. So, I take account of weight & compactness, as well as quality/durability & ease of assembly. I've used Sierra Designs, Black Diamond, Eureka, North Face, and most recently MSR tents; and longtime back, Egyptian cotton, and in Africa, canvas.
Currently, I use an MSR Hubba Hubba. it's a 2-person affair, well-made, light, easy to pitch, not too expensive at $300 Cdn. I've used it with and without the inner (mesh) tent, the inner tent essential for summer camping in Ontario, on account of the bugs. Two vestibules, so there's space for gear. The inner tent is snug for two, very spacious for one.
Drawbacks: I've found that it's prone to condensation in humid/cool weather, although with practice one can set up adequate cross-ventilation by playing with the flaps of the vestibules. Also, unlike some brands, as (I think it was) Pete of NZ mentioned, if you pitch it in the rain, you can't set up the fly first and then assemble the inner tent from within.
However, I get around the rain problem by using a tarp as well -- have an Integral Designs Siltarp, which is crazy-light, and at 2.4 m x 2.9, lots big enough to cover all/most of the tent tent, bike(s) and gear, and have space left over for cooking. I first started using tarps on canoe trips, and I now find them so handy as to be essential: wind shelters, rain shelters, etc. So, when I pitch camp, that's usually what goes up first. (That can either be a bother, or a keep-your-brain-young exercise in angles and tensions.) Of course, it helps to have trees!--but I live in the Ottawa Valley, no no problems there...
Good luck with all this,
John
PS: Here's a couple of examples of tent + tarp, on my recent ride from Amsterdam to Vienna [these look like very weird links to me, but I coped them from Dropbox, so they should work.]
