I don't know where you're from but if you're from Australia, Ray's Outdoors have this specially made bike touring tent which you and your bike are meant to be able to fit into. Only thing is, I reckon its heavier than it needs to be, about 2.5kgs from memory, so you're probs better off just going for a tent with a bigger vetabule (spelling?!)... Also it has a picture of a bike on the outside.
