Love this. Reminds me of Winogrand's Leica:

Canon SD20
I used it A LOT. I snapped that photo of it before I lost it. I think I left it in a taxi.
Here is a reference pic of how small it is:

Traveling on bike with an SLR is a pain in the butt no matter how you look at it. I hate to say it. I'm speaking from experience. When I shot BMX, I would have to carry my SLR while riding to different spots with the guys doing tricks. I used one of those backpack SLR case things that looked like a school backpack. It sucked. You had to get off the bike and lay the bag flat on the ground to get access to the camera body and lenses.
My advice. Find a small camera and learn how to make great photos with it.
