I just put new tires and tubes on my brother's old school Schwinn 10-speed after it sat in the garage for 16 years. I saw this little Schwinn bike computer and thought I'd give it a try, and it has worked really well. We have a nice paved 13.55 mile trail in town, and using this bike computer has made that trail that much more fun. I can know how far I have to get to the end of the trail and how far it is back to my car, and I am really pleased with it. For the money I think it is one of the best little computers you can buy!
