I finally did something to my bike to make it my own (besides a few stickers). Snce my dad won't let me do any mechanical upgrades on my bike, I decided a speedometer would be cool. However, I'm poor, so I bought a speedometer for a mtb. It works pretty good from what I have seen. (a quick test run in the backyard) I'm not sure how accurate it is, so I'll have to take a truck or my friend's speedo'd bike out next time and run them alongside each other. It looks pretty cool to me. I'm thinking of seeing if I can get a second sensor for my mtb, since you can take the actual computer off very easily.
