Third, you can't always find a tree or post to hang a hammock from (ever driven across the Great Plains?).
I've also done a lot of backpacking. As others mentioned, you don't have to worry about carrying much food on your bicycle. But you do have to carry adequate supplies of water. A CamelBak may be an option in addition to water bottles, although I don't think I would want something on my back if riding all day, day after day.
Look for lightweight clothing that can be easily washed and dried. That will really save you a lot of bulk.
Apparently you didn't use a Hennessey Hammock. These have a very loyal following and are actually quite comfortable. You lay flat in one, not bent. There are products to help with cool temperatures that don't come close to tent+sleeping bag+sleeping pad weights. Besides, in summer months, the cooling effect can be beneficial.
Hammocks aren't perfect and have their drawbacks, but they are a viable alternative to the traditional tent.
