Don't want one that has attachments on the fork/wheel
You'd need to get a GPS if you dont want fork attachments. More expensive tho.
I have a garmin forerunner that i use on my bike. Its designed more for running but works fine and gives me all the info i want.
Computers with fork/wheel attachments are much cheaper tho. I needed one for my uni project and managed to get one on ebay for 99p. It was brand new and had wireless sensors.
