I don't "bike tour" but I'm a photo enthusiast. I totally love my mini Nikon and sportcam combo. I would have no problem ditching the SLR while bike touring especially considering the size/weight issue. while bike videos are truly boring and mini cameras take video too now, I like the sportcam cuz it's waterproof and has an awesome wide angle and takes still as well. the timelapse settings cam be fun too.
