Featuring the Schwinn brand Americans have trusted for over one hundred years this bicycle computer mounts directly onto the frame of the bicycle, providing the rider a clear view of all speed and distance measurements. Featuring a no friction and no contact design, this computer measures the amount of turns by the wheel to provide an accurate calculation without the need to touch or interfere with the performance of the wheel. PTI Sports products are designed with safety as the first and foremost concern and are constructed of high quality parts and materials to prevent degradation over time. Thoroughly tested, our products last through years of use before they are recommended for replacement, ensuring safe cycling for years to come.
The folks at Schwinn obviously know a thing or two about bike accessories and this 12-function instrument should come in handy for anyone looking to use their biking time for something other than a pleasant pedal around the neighborhood. Attach it to your bike or hold it on the attached cord and get information on your speed, average speed, maximum speed, trip distance, odometer readings, total distance, ride time, and more. Bearing in mind that it's hard to push a lot of buttons while biking, the device features a single button control panel, allowing you to get the right information while still staying upright on the bike. --Charlie Williams

Wheel size must be entered when the unit is first power on. This is the circumference of the wheel in millimeters. A conversion table is provided in the instructions; however, it can also be calculated as:
Diameter in inches times 25.4 = Diameter in millimeters
Diameter in millimeters times 3.1416 (Pi) = Circumference in millimeters
22" x 25.4 = 559mm
559mm x 3.1416 = 1756mm
I really like the scan feature, which cycles the display through distance, maximum speed, average speed, and trip timer. Even in "scan mode" speed is always displayed. I found the instructions unclear in explaining how to place the unit into scan mode; however, I learned through trial & error that you press the right button multiple times until you see "SCAN" displayed below the little man on the bicycle. Then press & hold the right button for a few seconds and it should start to cycle through the displays properly.
Speed comparator shows a "+" if you're traveling faster than your average speed or "-" if you're traveling slower than your average speed.
Finally, another feature that I really like is the fact that the unit powers itself off after five minutes of inactivity to save the battery. The unit can also be removed from the mount on the handlebars for storage when not in use.
05/07/2011 Update: This bicycle computer uses an LR43 button cell. They don't seem to be common in department stores, as I could not find one locally. I'm most likely going to have to order one through Amazon.
However, the catch on the mounting bracket is terrible and the speedo will loosen itself and fall off with ease. I saw it fall once. I wasn't so lucky the 2nd time and it is lost forever.
I bought a replacement and the catch is loose on that one as well. So a brand new speedo is held onto the mounting bracket with duct tape. It's sad that quality control went out the window.
I imagine all of these cheaply made Chinese bike computers will have the same fate, so a fair price for this is $5-6. I can't buy the Schwinn name on the device for that price, but I can get the same exact device at that price shipped. Get something better or try to pay as little as possible for something that will only really last one year or maybe 2000 miles.
About setting wheel size. For those that are absolutely anal about accuracy, borrow someone's GPS and use it to calibrate the wheel size setting. The 2155 for a 700 size worked fine for me, a little off compared to the GPS but since I don't see myself going for a bicycle land speed record, don't really care that it's a little off. However, was bored and so started changing the size setting by a couple numbers at a time and now have it matching the GPS exactly.
One note of caution to mountain bikes and hybrid riders with suspensions - allow some slack across the suspension area of the front forks or you'll snap the wire the first time you compress/decompress the suspension hard. Oh and if you are old like me and can't see worth a darn, get some powerful readers to follow the instructions! They're are either making install instructions smaller everyday or my eyes are getting worse faster than I thought.
