Editorial Review
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

 GREAT Little Bike Computer August 4, 2010
Barry Brown (South Carolina)
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!
 Some Thoughts July 27, 2010
FrontPage (Baltimore, MD United States)
I have used this electronic odometer only once, and after I put all the info into the device (26 inches each wheel) it said that I had ridden my bike (a 26 inch hybrid) for almost 11-1/2 miles. So my unit is VERY inaccurate, since I googled the distance and it added to only a little more than 8 miles - 33 percent less. Other thoughts: As I started to put the computer on my bike I saw that the mounting "hardware" consists of only several plastic zip ties, as though the manufacturer even concedes that it won't last way too long (or perhaps that the user will upgrade to something better?). Everything else that I have placed on my bike has mounting hardware that's much more permanent instead of these small white zip ties.
The cable also just doesn't look very good on a nice ride. It appears cheap. I was also worried about how the small magnet installs on the spokes, by using a screw and its plastic casing which wraps around the spoke. Immediately I could imagine vibrations moving the magnet or making it wiggle free; once this ever gets lost, you can't measure anything.
That same afternoon of my first test, I stopped at a Subway for a 6-inch sub. The LCD screen had pretty much turned black from sun exposure, and the heat was focused into the center portion of its screen. After about 10 minutes I started being able to read the numbers again.
The concept is nice and the computer scan is a neat feature, but when someone wants to gauge their trip totals accurately, what's the point in having this if you still have to Google your trip to get an accurate distance? Maybe I should just pocket my GPS and let it track my trip instead, or just hop back on the web to add up my trip totals. I wish I could write something more positive.
A good, inexpensive bike computer July 1, 2010
Duncan Brown (Fairfield, IA USA)
This Schwinn installed very easily, is quick to set up, and yields useful information when riding. I like the + - symbols that show whether you're exceeding or falling below your average speed. The display is easy to read, and this just bike computer just works.
Take care in setting your wheel circumference in metric units; I found a good conversion table on [...] (in his Bike Computer section), which lists various wheel sizes and their circumference.
I had to read the instructions in order to learn how to reset the trip totals properly--change display to distance (NOT odometer), then hold the left button for two seconds.
 Inexpensive, but works just fine... June 23, 2010
DeeMee (Alabama)
For so little money, hard to go wrong unless the product is defective. It wasn't, worked as advertised and quite accurately. Simple to install. Fairly easy to use.
Has a decel/accel (speed tendency) feature which isn't too good. Has a little picture of a cyclist and wheels on it spin forward or backward to show when you are acclerating or decellerating. But it is too small, and hard to see which way the wheels are spinning. Much better would have been an easy to see arrow pointing forward or rearward. Then again, I don't find much use for this, as you normally feel in the pedals if you are speeding up or slowing down.
The plus or minus sign next to speed to show whether you are above or below your current average speed is sometimes nice to have. Other than that, it has speed, average speed, max speed, and a totalizing odometer plus a scan mode which switches every four seconds. I found it accurate especially after bothering to measure the distance in millimeters of one loaded wheel rotation. Simple to input into the device once you have done the measurement. The built in clock function is nice also.
The unit only counts time on the timer when you are moving. This is nice as it doesn't interfere with getting an average speed or riding time should you stop for a few moments. Unit also switches off when wheel isn't moving to save the battery.
I find it seems to do some time averaging of the speed readout which takes 3 seconds to fully even out. Don't know if others similar products work that way, but really this doesn't interfere with the use of the product and is only the result of having a sensor that pulses once per wheel revolution. It also doesn't read below about 2.4 mph which of course is slow enough you are barely able to stay upright anyway.
I also noticed it sometimes double counts every few revolutions. The distance will jump two thousands of a mile rather than one. Maybe a rounding error or some such in the electronics. I have counted rev's of the wheel over a known distance and it isn't counting twice the overal distance shown is accurate. So probably a non-problem unless you compulsively watch the distance readout while riding.
I haven't owned one of these before having only used simple mechanical speedo's and odometers in the past. But this works great and is a handier more useful device. Unless you need cadence or detailed pacing not sure what else you would want this device to do. Cheap enough to replace if damaged, or buy multiples if you have several bikes. Would rate it 4 and 1/2 stars. Just not quite perfect or it would get 5 stars.
Great Computer; Less Expensive At Walmart June 20, 2010
Jackie (IL, USA)
I had a little trouble following the directions but within about 15 minutes I was riding my bike with the computer. I love all of the functions and being able to tell how far I have gone on a particular ride and if I am staying in the mph zone I like to stay in. My only suggestion would be to go to Walmart where this exact same model by Schwinn is $10.00. It is located by other bike accessories.
