Product Description

Amazon.com Product Description

Sigma Sport's BC 1606L Wireless Computer with Cadence is the top model for riders who demand precision from each turn of the crank. This version of the BC 1606L DTS wireless succeeds in this not only by providing a better overview of the essential information during a ride by hiding the total accumulated functions in lieu of specific data points, but through its backlit readout that delivers optimal readability of information even in the dark. In addition, an integrated storage chip prevents the loss of set values during battery change as features such trip section counter, timer, and second wheel size are programmable. The set is equipped with a digital radio sensor with the receiver integrated into the bike computer. But the thing that sets this unit apart is the simultaneous transmission of speed data from the front wheel and cadence data from the turning on the cranks. Comparing these two the handlebar mounted computer is able to output more accurate data that is crucial to the training schedule of serious riders.

Digital Transmission explained.

A peek inside the BC1606L Cadence DTS' box.

Digital Transmission System (DTS) Explained
With 2-channel radio transmission (km/h and pedal frequency) and 100% digital encoding without data loss, the DTS system guarantees 100% data security of current speed and pedal frequency values during wireless reception. It does this by calculating all relevant data, encoding it and transmitting it in data packets to the integrated receiver in the bike computer. Disturbances such as power lines or mobile phones are no longer a problem as transmission is carried out over the so-called low frequency. A double security system also ensures that only the data packets from your own transmitter are evaluated by the receiver. This means that group rides are no problem.

A further security measure is redundant data transmission so that no data can be lost. The size and quality of the receiver has also been optimized by a specially developed Sigma chip (ASIC) and integrated into the bike computer which also saves on battery life.

This review is from: SIGMA BC1606L CADENCE DTS Double Wireless Bicycle Speedometer (Sports)

This computer has a lot going for it. I bought it specifically because I wanted wireless cadence, and this was as cheap as I could find it.

It was fairly easy to install, despite the cryptic instruction manual. It comes with strong rubber bands to attach most of the components, so they can be installed and removed without having to cut zip ties. I have a little trouble keeping the cadence transmitter in place, but only on really bumpy sections or when I throw the bike in the car.

The display is excellent. It's incredibly easy to read, and I love the fact that it uses *words* to convey what data you're looking at. To me, this ended up being the best feature. All my past cyclometers had tiny icons with no meaning.

Half the functions are accessed by one button, the other half by a different button. Things like the clock are in one set, while speed, cadence, and trip time are in another. This works well for me.

Usually, the computer will start up when you start rolling, but sometimes you have to hit a button to wake it up. This is a minor annoyance.

It has dual bike functions with the optional kit (though it won't do cadence on the second bike). I don't use this right now, but I'm considering it for my mountain bike. When the computer on that bike breaks, I'll probably do just that.

All in all, it a pretty great cyclometer. It works as advertised, it's inexpensive for wireless cadence, and the display is awesome.

This review is from: SIGMA BC1606L CADENCE DTS Double Wireless Bicycle Speedometer (Sports)

As others have pointed out that the instructions are a bit cryptic, none the less, it is accurate. The O-rings in my opinion are to help in locating the speed and cadence sensors on first installation, not a means for sole placement. There are plenty of supplied zip ties to secure the sensors once the optimum locations are found.

Installing the batteries in the speed and cadence sensors require a supplied special tool to lock the battery door. I think that a better way would be to mold in a coin slot instead. But thats their design. Make sure you align the arrow and dot when installing the battery door.

Placement orientation of the sensors are essential. Make sure you look at the pictograms to see that the sensors are in the correct location. I installed the cadence sensor in the wrong orientation at first and could see that the crank magnet was being sensed, but it didn't register on the computer. Looking a the manual again, I see that the cadence has to be located on the horizontal wheel stay. After I relocated the sensor here, the cadence works fine.

I did have a problem with the cadence sensor, the battery check light would not show an indication. I called Sigma customer service, got right through, there is a little "tang" on battery door that had broken off. Sigma customer service is sending a new one, 1st class mail. In the mean time I jury rigged a new tang on and got the cadence working, waiting for the new battery door for a permanent solution.

This product does everything I wanted in a wireless bike computer with cadence. I didn't give it 5 stars because of the battery door. For the money it's hard to beat.

This review is from: SIGMA BC1606L CADENCE DTS Double Wireless Bicycle Speedometer (Sports)

Although I don't ride much, I wanted a computer with cadence so it could also be used more easily with a stationary trainer in the winter without having tomess with wires. This product seems to work great on both rode and trainer. The only issue I have is that I keep bumping the cadence transmitter out of place, especially when transporting the bike, so that I have to reposition it before every ride.
