If you are going ultra light, ditch the tent for a tarp and/or maybe a bivy sack. Kinda depends on what level of comfort you want and the weather though. You can put up a decent lean-to with your bike supporting one side and staking it to the ground on the other side. I prefer to bring a tarp and bivy sack so I have somewhere to keep the gear dry and cook without getting wet when it rains.
