In theory, you can fix most cameras onto your helmet or bicycle by using an excessive amount of duct tape. Sure, you'll look like a mess, but your camera will look even worse if you dropped it.
A better option would be Oregon Scientific's ATC5K. Designed to capture adventurers' conquests on the most dangerous trails, the shockproof shooter can be mounted onto helmets or bicycles to record those awesome first-person perspectives on video.
Like conventional digicams, the video resolution is 640 x 480 pixels at 30 frames per second, which is good enough to view on most displays. The internal memory holds 32MB of still pictures or videos, and the SD expansion slot supports up to 4GB. Unless you've brought enough AA-sized batteries for your expedition, we suggest you keep the viewing on the 1.5-inch LCD to a minimum.
The ATC5K will be available from August and will be priced at $199.
