I have had some great success by optimizing my camera kit for biking. Since I've noticed that I get more "keepers" the more I move about, taking the camera with me while biking is probably the easiest way to ensure a number of photos end up the way I like them.
But having a backpack - even a really good one like the Kata 3N1-20 that I use - while biking isn't as comfortable as it should be, so I set out to find ways to strap the backpack to the bicycle. While possible, that didn't seem very optimal. The backpack had to be tied down and I didn't quite trust it to not fall off. But I also didn't feel like paying a couple of hundred dollars for a bag.
The tripod went strapped on top of it. Throw in a little foam, adhesive velcro strips, and dividers, and I had a versatile system where I could either carry a camera and three lenses; or the camera and a lens with space for other items.
Like a little camel.
