and to add, I have camped, canoe camped (trips where one travels by canoe each day, set up camp, move on---hey, just like bike touring) my whole life, and then did bicycle touring.

I have never used a one wall tent, here in N. America, the vast vast majority of tents are with a inner section with some meshing (some more than others) with a waterproof floor and sides that extend up to perhaps a foot high, then a waterproof "fly" that fits over the top, but with airspace between it and the non waterproof area part of the main body, for ventilation. Some tents designs have better ventilation in general, with less condensation, but frankly, any reasonably priced tent bought at an outdoor supplier type store will be well designed for ventilation, rain-storm-wind resistance and ease of putting up.

other than the pricey single walled tents that backbackers sometimes use, these types are usually youir cheapie tents, not good materials, and most often seen used by people who do not camp much.

as for "putting up time" my 2 person tent , free standing , that Iused on all my bike trips years ago, was a Sierra Designs tent, reasonable design, good in rain, if I wanted to not put up the "fly", and it was dry, i could.
It takes only a few minutes to put up, 2 main poles, bingo. I recall timing it once on a bike trip and it was something like 2- or 3 minutes....not long, and this is a 20 yr old tent. Many tents today are slightly better, lighter etc etc and not super expensive.

think of it this way, you buy a crap tent for 50 dollars, its crap, you get wet, poles break or whatever, you hate it, you toss it out etcetc

you spend 200 or 300 on a well designed tent by a known tent company, it works better, its good in,rain, you have better ventilation, the zippers dont break cuz the quality of parts are better, you keep for years.....bingo, happy as a clam and cheaper in the long run.

believe me, if you are bike touring and have biked all day, youdont want to screw around with a cheap poorly designed tent that means you cant sleep soundly knowing that if it rains in the night, you wll have wet stuff , sleeping bag etc etc that you will need to pack up wet.......yuck!

I realize younger people may not have as much money to spend on stuff, but basic stuff like a tent, get a reasonable one and it will serve youwell AND encourage you to keep on doing outdoor stuff as you wont be soaking wet and pissed off cuz the zippers broke in the middle of your bike trip.

In my humble opinion, take it as you wish.
