Description of PTI Schwinn 12 Function Computer
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

The only problem with it is its in KM/Hr instead of Miles/Hr, otherwise, for the price, it works great.Customer Review: Inexpensive, but works just fine...

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.
Customer Review: One of the two failed within two months
Sport shop rating: 4 Stars
We bought two - one for my bike and another for my son't bike. My son's unit works fine, but my unit quit working within two months. The part that goes on to the fork (sensor) isn't sensing any more. I know, it isn't expensive, but I hate to throw away the entire unit when the real computer is doing fine.
The product is adequate for what it is intended for. It has more features than I was hoping for when I bought it. Installation is easy. Learning to use it is a little bit challenge due to the poor manual, but you'll quickly figure it out.
I will certainly recommend it, but be prepared for it to die prematurely. In my case it died just before I was to venture on a training ride - not a good timing. You see, I depend heavily on this and my turn lists to figure out the training ride route. Without the distance assistance, I had to constantly check the street signs.
I am seriously thinking of buying the same model to replace the broken one.
Customer Review: Works as expected
Sport shop rating: 4 Stars
It works as expected. It is not difficult to assemble and attach to the bike.
The alignment of the magnet on the wheel is the key. The first time I had it too close and it used to hit the other "receiver" on the bike. I moved it a bit and it seems to be ok after that. I have used it for more than a month and it does what its supposed to do and reports all the statistics as mentioned in its manuals. I am not very sure how accurate they are, but it seems to be fairly accurate and tht is good enough for me.
Cons: I am just worried that the magnet that I have attached to the wheel is going to fall of some day and this would make this whole unit useless. The magnet is in a plastic casing and is attached to the spokes and it does not seem to be very secure.
