No, you need two trekking poles to tie up to. Light weight, telescopic, so easily fit on the bike, and don't need to be the really expensive ones. Then you can pitch a bivvy anywhere.
If you need any tips on this, go to www.backpacking-lite.co.uk, look at shelters, then tarps. A wealth of info on bivvys, tarps, even the best knots to use and where to use them - happy bivvying!
