I'm thinking it needs to be big enough for 1 person + a bit of gear, able to be pitched preferably without poles (although carrying one lightweight pole on the bike wouldn't be a big deal), and also be flexible enough to be pitched close down to the ground in bad weather, or higher up for the occasional non-rainy trip. Bonus points for using wheels and/or bike for supports.
Here are a couple of attempts. Once I used the yellow guylines to steady the bike the first one was fairly solid, and the one using both wheels was surprisingly solid, though I'm not sure I'd trust either in high winds.

Any thoughts? Cheers!
