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

I own two of these--one of which I installed on an old exercise bicycle and the other I installed on a street bike. It operates based on a magnet mounted to a spoke and a pickup sensor on the fork. Very easy to install and mounts using four zip ties--two for the sensor and two for the computer, itself. Functions include: (1) Speedometer--configurable as MPH or KM/hr, (2) Tripmeter / Distance, (3) Odometer, (4) Trip timer, (5) Maximum speed, (6) Digital clock--configurable as 12 or 24 hour, (7) Average speed, (8) Scan, (9) Freeze frame memory, (10) Speed comparator, (11) Speed Tendency--indicates acceleration or deceleration, and (12) Odometer reset. Overall size of computer is approximately 1-3/4" x 1-3/4" x 3/4" (not including mounting bracket). Display size is approximately 1-1/16" x 7/8".

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

Example:
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.

I've had one of these for about six months and just ordered another from Amazon. This little computer is accurate, reliable and easy to use.

The display shows your speed in large letters and has a selectable smaller readout for whatever function you choose. I wind up having it show speed and time all the time. If you're satisfied with a simple, cheap speedometer and only occasionally use the other functions, this is the one.

Here are some hints that fairly eliminate most of the small complaints.

1. Install the magnet close to the wheel's hub and adjust it (twist the sensor in) so that the magnet passes as close as possible without touching.

2. Remove the computer when the bike is not in use. It has a quick release; store it inside or in your pocket and the battery will last.

3. Leaving it outside in direct sunlight may cause a dark splotch on the screen. This is normal for led displays, and goes away in a few seconds. Also see hint #2.

4. Read the manual to learn how to reset it (which buttons to hold down), and to calibrate it for your wheel size.

The only issues I've had: the buttons will eventually get some "play" if you use them a lot and become contrary, and I need to be careful to secure it firmly in the quick release mount (so that it doesn't fall out when I hit a bump).

I bought mine from a nearby Wal-Mart and it's worked perfectly so far. Having never installed one before, I just took my time & had some extra zip ties ready...just in case. The only tool you'll need is something to trim the ends off the zip ties when you're done. I like the "scan" mode which flips thru max speed, avg. speed, distance, total time, etc. On the down side, I bought another for my son's bike. It either had a bad sensor or a broken wire from the sensor to the unit. It never did work. I took it back for a refund. For $10 - what do you expect? You may get one that works fine - you may not.

I just bought mine a couple days ago at a local WalMart, for a wee bit more than it costs here on Amazon -- I didn't plan well and needed it quick. Set it up in 5-10 minutes max, it seemed to work fine. Gotta be patient to put the magnet as close to the sensor as possible without touching, though. That is the only "time consuming" part of the setup. The owner's manual lists a few wheel sizes and the corresponding C factor that you have to enter in the computer, and fortunately mine (26 x 2) was there, so I didn't even have to mess with measuring tape and calculator.

Today I had my first ride with it, and it performed great for such an inexpensive product. I rode to the soccer field, which is exactly 5 miles from my place (as measured on Google maps and by car). Lo and behold, the little computer measured exactly 5 miles when I got there. I was impressed. It gives the current, average, and maximum speeds, odometer and trip meter, the riding time, and has a regular watch. It tells you whether you're speeding up or down, and whether you are currently above or below your average speed. The ONLY thing I miss on this unit is a thermometer. It's perfect apart from that.

If I wasn't in a hurry, I would have bought the 17-function Schwinn one that is here on Amazon, since it costs a little less than I paid for the 12-function one and measures temperature -- although I don't know how accurate that is in direct sunlight anyway. I don't care for measures of calories and stuff like that, since I don't believe the manufacturers know my metabolism.
