Sigma 1609 sts speed and distance no longer work

Sigma 1609 sts I changed the battery in the front sensor after the indicator showed that the "distance" battery was low. Since I replaced the battery (I've tried two new ones) I can't get speed or distance to work. I tried pressing the button to "sync" but that hasn't worked either. I have successfully changed the battery for the cadence sensor in the past and it continues to function. Any ideas?

SOURCE: when I training indoor my edge 305 doesn't show me

Try start your training device outdoor for a check. If then it is working, the issue is about the device needs to see sattelites to perform measurements and register speed.

You may try switch GPS device off, which is said to be an indoor mode for training.

SOURCE: Hi, My sigma bc 1009 sts

Well, it IS wireless. Perhaps the distance or line-of-sight isn't right. As a test, hold the receiver in your hand and hold it closer to the spinning wheel transmitter.

SOURCE: Sigma wireless bicycle computer.

Did you throw the magnet on the crankarm? If not check the alignment of the transmitter and the magnet - sometimes they need to be quite close. Sometimes they just fail. I have seen instances where cadence worked and speed didn't and vice versa - so the unit is transmitting perfectly, but one of the sensors has gone bad.

SOURCE: 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.

How can I get my sigma 400 bike computer to display speed and distance?


Need to know if it worked before, and what you have tried so far - new battery, repositioning magnet, making sure unit is seated well in mounting? If you take a magnet and move it back and forth right next to the wheel sensor and get no response then either the signal is not getting to the computer or the computer is broken and needs to be replaced.

Not registering speed


Check your magnet is aligned with and adequately close to the sensor, and that the sensor is not too far from the computer. Also check batteries. Try taking the computer off the bars and moving it nearer to the sensor to see if it is a range problem.

Syncing with Sigma BC1009


Had this same problem and nothing worked after trying everything I could think of. Speedometer would never display a blinking 0 (just stagnant). Turned out the computer mount on the handle bar was turned around backwards. The sigma letters go towards the front of the bike. Placed the device in the mount, the 0 started blinking and sync'd up with sensor. Finally works!

How to open the sensor on rear wheel of Sigma BC1609 wireless odometer. I need to change the battery and there is no slot (to use a coin to open.) Instructions say "use a tool" what tool?


They're talking about a special tool with two little pins on it for turning the battery cover. It's the item on the far right of the 3rd page of the manual. I imagine a bent paper clip might also work in its place.

The manual is here http://www.sigmasport.com/en/service_center/produkt_support/bikecomputer/fragen/?jahrgang=7&produkt=93&gruppe=1&sprache=2&typ=bikecomputer
