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
Sports reviews of PTI Schwinn 12 Function Computer
Customer Review: Great Features for the Price!
Sport shop rating: 5 Stars
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.
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.
Customer Review: Great little gadget
Sport shop rating: 5 Stars
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.
Customer Review: Best Value bicycle speedometer.
Sport shop rating: 5 Stars
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).
Customer Review: A good, inexpensive bike computer
Sport shop rating: 5 Stars
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.
Customer Review: GREAT Little Bike Computer
Sport shop rating: 5 Stars
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!
