12 Function Computer

this is a good product if i could get it calbrated.

at least three or four times.... I dont mind lookin 4 the damn thing, but this last time it reset itself to 'new'.....oh boy now I have 2 look for the instructs to program my 1600m back in....the first one had 1900m...maybe if I can figuire it out I will add the miles together. lol...

Bought this to replace a Cateye wireless that had too much interference from other devices. So far, I think the Schwinn is a better unit than the Cateye. Quality seems very high; buttons work solidly. My first test shows it right on the money in accuracy. I'm extremely pleased especially considering the price. Based on the "falling off" reviews I'm going to keep a close eye on the latch mechanism, but my first impression is that the unit is firmly attached. For those of you who can't get the accuracy, measure the wheel circumference using a dab of paint (measure the distance of one rotation between the paint dots), or use a tape measure to take a measurement around the tire tread. Then do the conversion math to mm's, and enter it into the computer.

I can't understand the bad reviews I have read. Am I among the MINIORITY who has had good luck? First, I read the instructions and did as they told. Very accurate speed and miles (I checked with GPS and other accurate sources). So as long as you put in the precise calibration for your TIRE (take the EXACTdiameter tread top to tread top and multiply by Pi [3.14159] and you have your calibration figure), and you are WITHIN that 1mm distance from the magnet to the sensor (Very small gap barely enough for a few sheets of paper to fit through - and be careful to NOT overtighten the magnet, but tighten the magnet and sensor enough that they do not move), there are no problems that I have experienced. I am a HEAVY DUTY cyclist with too much time on my hands. I have ridden just over 5,000 (yes that's FIVE THOUSAND) miles over the summer (the calendar summer), some days approaching 200 miles. I have not had a single problem. The speeds have been very accurate. I have been on rides that are over 80 miles one way (very accurately measured by GPS), and the computer was right on the money with a considerably less than 1% discrepency. During the height of daylight (around June 21), I have been on the bike 14 total and continuous hours, and the unit did not stop working. This unit has NEVER fallen off my bike. What can I say? All I did is follow instructions and did the installation very carefully, and the thing works. I have been using mine since the beginning of may (today is Sept 29), and it's still working after 5,328 miles and 386 hours of use over a period of 4 months and the battery has not died yet. If one does not feel like spending 40 bucks and more for more elaborate computers (with functions most will not use unless you are really into professional riding and/or want to monitor your heart rates - etc.), I highly recommend this. it's accurate and it works if you use it correctly.

They must fall off a lot. I've found 2 of these things in my travels. I've never found any other brand. I bought the Cateye brand and had no problem. Looks like a good little computer but based on the reviews and after finding these, I would never buy the Schwinn model. It doesn't do you any good lying in the dirt. Hope they fix it!

Worked fine for the ten days I had before it fell off several times and finally rolled into the bush while riding downhill on a "paved" road in France. Unable to locate the computer. Would I buy one again...NEVER. What the hell use is a computer that constantly falls off your bike? I would think the company would read the reviews and revamp their housing system that holds the computer in place...if they gave a damn about their product and the consumer. This product was purchased at Canadian Tire in Nanaimo, B.C. Peter.

I tried for two days to get a reading on the computer - moving the sensor, moving the magnet everyplace I can imagine still was not able to get this device to work very disappointed.

love it if i could get it accurate

I didn't even get to look at my first one I took the 20 minutes to set it up got the tire size vs rotation all set checked it out with a few spins of the tire jarred the handle bars to make sure it wouldn't fall off , Then I took off down the drive way took a left did a quick wheelie as I always do when accelerating maybe 6 " off the ground. Checked traffic as I crossed the road to get to my favorite trail. Hopped the curb smoothly I dropped down the first hill on my favorite trail I get to top speed at the steepest part of the trail, look down for the first time at my brand new bike PC and it's GONZO. not there erased, zippo "not the lighter either" , nada. el~gono , syonara , " vacate is the word" So I crank on both breaks screeching to a gravel pinging and dirt flying all over the place stop in about 15' Dust everyplace I can even taste it " I just start to sweat so of course all the dust is now sticking to me like a magnet to metal, I reluctantly retrace my tracks back up the 45° drop off "pedaling mind you up hill ,Back to the road I hear a crunching sound as a car goes by then I see it tumbling over and over in like 3 pieces. I let out the usual colorful metaphors AKA ~*#$@%!^. I Salvage the battery and then leave . Cleaning up the mess of course So I instead ride to the local superstore devil and drop the chunks on the C/S desk and say "this is defective" it fell off and got ran over by 25 cars and trucks . Do you have your receipt? Yes I do , I cant return this ... how do I know you installed it correctly I said "do you see that mountain bike over there?" yes she said I BUILT IT ONE PIECE AT A TIME. then I showed her several reviews saying the exact same thing as my complaint it bounces off on the first bump. She says "How do I know they installed it correctly" I peaked and said " Look not everyone is an incompetent $#%^ that cant screw in a light bulb without 4 people helping them " I put it on right & it fell off " ... So I bought another one and this time i put a dab of superglue on it been holding through the worst of trails W/ branches whacking it and the likes I even dumped it once when I got close lined by a low branch it is still on there & when you want to remove it "Replace a battery" just take A DROP OF RONSONOL LIGHTER FLUID AND IT RELEASES IT UPON CONTACT . Obviously don't cover the unit with either the super glue or the Roinsonol One more thing I figure if your at a spot where you don't feel comfortable leaving the PC on your bike . then you shouldn't be leaving the bike there either!! If I go to a convenience store or something I take my bike right inside with me & I leave it where i can see it . The clerks are 95% of the time cool with it . Remember folks a dab of glue can save you a few hours of stress in our "short time is sooo precious lives" Sincerely Rich McCallum Cape Cod Schwinn rider P.S.

The owner of the local bike shop offered me $450 for it 2 weeks ago. My brother an avid m/b'r as well likes it better than his 2,300 dollar Specialized M/B so those two scenarios speak volumes for this bike I must say <img src="http://i769.photobucket.com/albums/xx337/jumpa01/H1410016.jpg"> <img src="http://i769.photobucket.com/albums/xx337/jumpa01/H1410015.jpg"> <img src="http://i769.photobucket.com/albums/xx337/jumpa01/H1410014.jpg"> <img src="http://i769.photobucket.com/albums/xx337/jumpa01/H1410005.jpg"> <img src="http://i769.photobucket.com/albums/xx337/jumpa01/H1410003.jpg">

Had this one for 2 yrs. 2nd battery. not too bad. But had a bit of trouble finding one. We got a new type drug store, they had about every kind of button battery made. But not your fault, the printing on the battery package was micro in size. As to the falling off thing. The little catch that hold it on is the problem (too long too easy to bump). Also add the inch to metric factor. If you can still do 8th grade math, wheel size calibration is easy. The sun/heat thing fading is just a thing with all LCD types, had a watch once that did the same on a hot day. Over all it better than other in same price range.

It is a nice little tool but ours fell right off!! Not a hapy camper that I have to rebuy the thing. Guess we will duct tape the next one down.

Worked great, I loved knowing how fast I was going ha. Worked great, easy to setup, was pleased with 24hr time, just no problems. Looking through it now I clocked 54 miles in 4 hrs and 45 minutes. Looking for replacement mount because I always removed it from my bike when I left it alone and my bike got stolen so now I just got the computer piece.

Wonderful as far as the ability to set the tire size. Too hard to reset the distance, duration, and so on. Seems to just quit reading after about 30 minutes of riding. I verified the position of the sensor to no avail.

had very good luck with this computer. easy too read,

had 2 for over the past 5 years moved up to a wireless no issues other than finding the battery can be a bit of a pain to find and after the first battery change over i wrote down the tire factor in permanent ink on the side of the unit again for 15-20 bucks very useful and through rain and wipe outs had never fallen off.. like most things and vehicles your mileage may vary..

I bought this cyclometer about 12 years ago. I'm sure the style has changed a bit, but it's basicly the same as the new version. 12 function and all mounts are the same reads the same as the new style. I've probably put near 13000 miles on this one without a hiccup to talk about. Normal maintenance, battery changes and such. I did learn not to leave it in direct sunlight for a long time, the screen goes blank, but when it cools off it's right back to normal. I think paid $9.00 for it. I have only one gripe to speak of. After 10 hrs of riding, you have to reset the speedo or the time flashes. So I rest about 6 times a month.That's it though, I use Schwinn speedos on all my bikes, touring and recumbant. It's a great product as far as I'm concerned.

Overall Good Buy! Recommend. The instructions are not the most well written or best edited document ever, with some of the most important information you would find very helpful in the five step "Quick Set-Up" section actually found in the next to the last paragraph of the instructions. At least in the English version. The instructions are provided in multiple languages which adds a little "clutter" to the sheet. Of course, if you need to read them in French, you would probably think the English gets in the way. The various parts are easily installed, taking about 15 minutes from start to riding away. If you are even a little bit mechanically inclined you could install the various parts just by the logic of how they should work together without any instructions. That is, If you knew to mount the sensor receiver and magnetic spoke device within one mm for proper pick up That information is clearly and properly given at the right point. The trick is to actually find a place where you can get that relationship properly established on your bike, particularly if you have front suspension forks with a lot of variance in cross section, thus the distance from spokes at various points along the fork. (Tip: The pick up does not have to be mounted on the direct inside of the fork. Mounting on the edge closer to the front vs side can help find the magic "one mm" spacing. If you put it on tightly with the zip ties.) I put a couple of layers of old bike tire inter-tube material on the handlebar under the mounting bracket to dampen vibration. That also provides a little give and rebound when you pull the zip ties tight and help keep it in place with less road vibration transmitted to the computer. The real kicker is somehow knowing that "set tire size" really means taking an hour on the internet to find your tire size conversion factor which is really what has to be entered at Step 2 of the set up. (No help on the Schwinn website for this, I'm afraid. Hint Hint, Schwinn support group) The instructions just say "enter tire size" and up comes four blinking numbers. That's right - four numbers. Turns out, if you read all the instructions before you do Step 1 you will be given a chart of four digit factor numbers for various tire sizes - none of which may be yours if you have a newer style tire. No problem just Google "Sheldon Brown's Cyclecomputer Calculaton Chart" and you will find more info on how to set the proper number in various bike computers than you can process without a real appetite for math. But Mr Brown provides the resources and methods to easily find your factor in simple charts or formulas. Hint: It is not in the Schwinn instructions chart but 700x35C tires, common on today's hybrid bikes, use a factor of 2168. Now the four numbers to "set tire size", instead of the two (inches) or three digit (metric) tire sizes we think of, makes more sense, I hope. Better be careful and precise entering it the first time, as well as entering the time (12 vs 24 hr) and miles vs kilometer preferences because the slightest fumbling of a button push and the computer jumps to the next step without a way to get back, unless you want to keep removing the battery to start over. (Remember, this is Steps 2-4 of the Quick Set Up.) Then, after you do that a few times to get the set up done right when you finally get to the end of the instructions - after the installation of parts on the bike - directions to hold down both buttons to bring up the same set up options which you can cycle through easily to repeat a step. Putting this information at the end of the instructions instead of at the beginning where you go through the set is bad editing at best. But good information once you have it. But once you overcome the written instructions, you will find a very nice little computer that tell you everything you need to know about your bike ride. It does not count calories like the more expensive ones but who believes that is an accurate number anyway. It securely mounts with the included ties and gives accurate information. It removes with the a simple press of a release tab when you want to remove it from the bike and use it for a pocket watch or just make sure someone else does not do that while you are away from the bike. This computer is Good Value for the money. I don't see how it could fall off once much less twice as happened to another reviewer if it is snapped into place as designed. It is a challenge to read the LED numbers as you pass under street lights at night. For more money a backlighted screen for night riding would be nice but battery draining. I did not expect that for $12. I got what I expected and more.

currently using this computer on a motorbike with aftermarket 2cycle engine. so far the only gripe i've had was the small list of tire size conversions. my tire size was 26x1.95 which ended up requiring a bit of googling to get an answer on. no problems with mounting process, magnet seems sturdy, screen is lacking the problems i've read about in reviews on amazon. no issues with it bouncing out of cradle. all in all, worth my 11 dollar investment.

Great value for money, an excellent entry level cyclo-computer it was very easy to install and a very reliable unit. would certainly reccomend this unit to friends and family.

I've really liked this computer, but I had to calibrate it by checking off a mile in my car and then finding the numbers to correspond to it, but the computer itself worked well. Just as soon as I got it calibrated, the magnet fell out of the spoke attachment and those aren't sold separately. C'mon, guys. Superglue has existed for quite awhile now.

energizer 386 works The ones that came with two calculators did not work!!!

The computer works great, but it'll fly off your bike the first time you ride it. Either use duct tape or twist ties to secure it!

good item hard to find l r 43 or l 1142 battery.

I've had the 12 function computer for over 2 years, just replaced the battery. Great addition to my bike, and easy to use.

The computer works ok. The only problem is that if you go over bumps it will fall off - even if properly attached. The attaching mechanism is poorly designed. I have lost 3 of these computers and now I am adding duct tape to hold it on.
