I'll throw in a recommendation for Tarptents. Single walled tents that are good in spring, summer, fall (and light winter conditions). I use one of these for the occasional bike tour (haven't bike toured in 2 years) and more extensively for backpacking. I've got an older Cloudburst (no longer in Tarptent's lineup) and its similar to the current Squall or Rainbow tents. These are tunnel tents and should be long enough for two persons and some gear. And since they are single walled tents, they're incredibly light.
