SOURCE: i have a sigma 1606l computor what is the wheel

you can measure your wheel by placing your bike on a flat surface with the valve stem on the wheel in the bottom most position or 6 o clock position. mark the floor where the valve stem is. now roll the bike forward so that the wheels gets one full revolution and the valve stem comes back to the 6 o clock position and mark the floor at the valve stem. now get a tape measure and measure the distance between your two marks. Convert this measurement to usually centimeters. that will be the number that put into your computer.

SOURCE: What must be setting on wheel size if my bike

get a tape measure and measure the out side circunfrance of the wheel. This is you number. OR put a white dob of paint on the tyre and roll it in a strainght line until the dob of paint makes a 2nd mark, (on a path way etc) measure the distance. this will be the same as the first option. Generally its required in mm.

SOURCE: I need to program a sigma 906 for my recumbent

The number you are entering should be the circumference of the tire, measured in millimeters. 1254 looks pretty small for your wheel. You can get the circumference by rolling the tire one revolution and measuring the distance with a tape measure. I usually lay out the tape, start with the tire valve at zero, roll one revolution, and read the number. Of course this number could be off by a few percent as the tire isn't exactly the same size due to rider weight, air pressure, tire wear, and temperature. If the error is large you need to do some riding on a known distance, like a running track, and then tweak the number up or down slightly until you are happy.

Sigma BC 1609 Cadence Bicycle Speedometer reads my movement much slower than I am actually going. E.g. moving about 15, reads as 5 mph.

I had the same problem. It is caused because the mount is facing the wrong direction and your computer is swapping speed and cadence. 5 mph would mean 63 RPM of the wheel which probably what your pedal is actually doing. The wheel is actually turning at about 3 times that rate so if you check your cadence it is probably maxing out at 180 even though that wouldn't be possible.

To fix this, just twist your mount 180 degrees on your handlebars or stem and try again. That way the computer is correctly lined up with the mount.

Change from mh to mph

Push bottom button until you see TRIP in bottom left corner of screen. Then go to the back, and push the small button and hold for about 3 seconds. The WS in the top will be blinking, and the number will be blinking. Push the bottom button to scroll through until KMH is blinking. Then push the top button, to toggle to MPH. Now... you will have to rest your wheel size on this screen (the numbers) go to Sigma sports website and get the manual, then look at your wheel size on the side of the tire, put in the correct number for your wheel size. Once all this is done, then turn over and push the small button for about a second for your changes to take effect. the screen will not be blinking now.
