SIGMA BC1706HR DTS Wireless Bicycle Speedometer with Heart Rate Monitor
- 17 Functions
- Digitally Coded Wireless Speed & Heart Rate
- Easy to program/Tool Free installation

Product Description
The BC 1706 HR with DTS is the perfect solution for all fitness-oriented cyclists. DTS stands for digital transmission system (Speed and HR), providing zero cross talk with other computers and ensuring that the data on the computer is your own. The current, maximum and average heart rate are measured as precisely as an ECG for precise training control. Both the speed and heart rate are coded and transferred to the bicycle computer by digitally coded radio waves. All bike, time and heart rate values are easily and clearly read from the 3-line display. Handlebar and stem mount. 17 Functions Wireless Speed + Heart Rate: speed, avg speed, max speed, speed comparison, trip distance, total distance bike 1, total distance bike 2, total distance bike 1 + 2, clock, ride time, low battery indicator, two bike programmable, total ride time bike 1, total ride time bike 2, total ride time bike 1+ 2, memory back up function, Heart Rate, Avg Heart Rate, maximum Heart Rate, programmable trip segment, programmable timer.Amazon.com Product Description
The BC 1706 HR DTS with heart rate monitor is the perfect solution for all fitness-oriented cyclists. In addition to the trusted BC 1606L DTS bike and time functions the BC 1706 HR also measures heart rate. The current, maximum and average heart rate are measured as precisely as an EKG for precise training and control. Both the speed and heart rate are coded and transferred to the BC by radio waves (digital and coded). All bike, time and heart rate values are easily and clearly read from the 3-line display.

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 thing simply does not work. I wish I had gone ahead and spent more money and gotten something useful.

I like the concept of an integrated bike computer HRM, but this unit is a pain. It sometimes wakes up speaking German, other times it doesn’t want to wake up until a half hour into the ride. Apparently (according to the shop where I purchased it) you have to remove it from the mount before a ride, reinsert it, then spin the wheel so it synchs properly with the speed sensor. Just be glad Sigma doesn’t make your car’s speedometer, or you’d have to remove it every time you get into your car, and spin the wheel to make it work. Dumb product!

The Amazon listing clearly indicates this unit has two cadence functions. It does not.
According the the Sigmasport site you need to spend over $100 more to get wireless cadence and heart monitor in the same unit. Looks like Amazon gets a return, and I’ll have to look for some other solution

While installing the magnet to the wheel spoke – I guess I overtightened because I cracked the plastic holder. And the computer itself needs new batteries – right out of the box!
I wrote to customer service – and they were very helpful. When I mentioned the battery – they said they had changed their shipping methods to keep the battery separate in the packaging. Customer service sent me a new plastic magnet for my wheel spoke – and a new battery! What was not a great start – they made a positive experience.

seems like a good quality product, but as other reviewers have stated, the instructions are a bit skinny.
