This instructable shows you how to turn a front reflector into a universal bike handle bar mount that you can use to mount many different gadgets.
Step 1: Find a Bike reflector.
Universal bike mount system. Take those plentiful cheap reflectors that are on every junk bike out there. You might even ask your local bike shop if they have any laying around. They look like the one pictured. Some are mounted to the seat post and some are mounted to the handle bars. I've so far only used the ones mounted to the handle bars, but i could see some uses for the rear reflector.
