Bicycle Camera Mount for Under $1

Mount almost any camera that accepts a screw in tripod for under a buck, using stuff you may already even have.

What you'll need to make it:

1 x Reflector Mount (a friendly bike shop will give these away for free)
1 x Shim for reflector mount (also probably free at your LBS)
1 x 2 inch 1/4" x 20 thread count screw of your choice (pretty standard for most cameras)
2 x 1/4" wing nuts
2 x 1/4" washers
2 x 1/4" rubber washers

You might also need a drill with a 1/4" drill bit

The mount I had has 2 holes in it, make sure to drill out the farther one large enough for the screw.

You can use a mount that has only one hole, you'll just have the mounting screw double as the screw for the camera. Make sure you take into account that you'll need a 1/4" diameter hole through there when rummaging through their reflector bin.

Put the 1/4" screw through the bottom of the mount, put these things onto it in this order:

metal washer
rubber washer
wing nut (could also use a regular nut)
wing nut (upside down! this one is more helpful if it's a wing nut)
metal washer
rubber washer

the rubber washers were to help absorb shock. it's not perfect, but it does a better job than nothing. still looking for an improvement on that though.

I've got mine mounted on my handlebars for a front view. for a rear view you could mount it on your top tube under your saddle, most tripod mounts are offset, so depending on your model you might have a seatpost in the way. I'm using a Canon SD600 and it works just fine there.
