Dynamic, sporty, and elegant, the Sigma BC 1909 STS triple wireless bike computer is ideal for fitness-minded cyclists who place a high emphasis on measuring heart rate and calories burned. The BC 1909 STS, which is adjustable to fit two wheel sizes, displays your current speed, average speed, and maximum speed, so you'll have a good idea whether you're the tortoise or the hare on the bike trail. You can also compare your current and average speed on the same screen, or check the trip distance and total distance (the latter is only available after your ride). The computer even offers a programmable trip section counter, a roadbook that lets you create a back-and-forth itinerary.
The BC 1909 STS's HR functions include ECG-precise measurements of your actual, average, and maximum heart rate, along with a zone alarm that tells you when you're exceeding or falling below your target heart rate. In the process, the computer keeps track of your calories burned thus far. The BC 1909 STS also includes a number of time-specific functions, including a countdown timer that's perfect for racing against the clock; a stopwatch that keeps you sharp on intervals; a display for elapsed and total riding time (the latter is only available after your ride); and a time-keeping clock. And serious cyclists can opt to use the cadence functions (current and average), which help you ride efficiently both on the road and in the woods. You can also turn off the cadence functions while riding.
The BC 1909 STS is versatile in other ways, too, with the ability to automatically recognize a second bike. That means you can gauge the total distance and ride time of either or both bikes, a handy option for couples or friends who train together. Other features include a temperature display, seven language settings, a backlight, a battery status display, and a backup function that preserves your settings and info even when the battery dies. The PC-compatible BC 1909 STS is also available in a wired version.
The BC 1909 Triple wireless speedometer is for all fitness-minded cyclists who place particular emphasis on heart rate and calories. Includes 1 settable HR zone and temperature. Dynamic, sporty, and elegant, the Sigma BC 1909 STS triple wireless bike computer is ideal for fitness-minded cyclists who place a high emphasis on measuring heart rate and calories burned.

Customer Reviews

My girlfriend and I each individually purchased the BC-1909 computer for our respective road bikes. We both wanted to have Speed, Cadence ; HRM on one unit. We been on about 5 rides thus far and the units have performed as expected. We ride very close to each other and despite having the same exact computers, we have not had any cross talk issues -- the units simply do what they are designed to do. I installed both computers myself and installation was very straightfoward. The units look and feel high quality and the display is large, sharp and legible. Thus far, we have had zero issues with HRM monitoring on either computer. If I had to be critical I would make one primary observation -- the headunit isn't super snug when locked onto its mounting bracket. While is does make a clear and distinct click noise when twisted onto it bracket, it is still not as solid a connection as my old wired VDO unit. The end result is that if you are not careful, it is possible to accidently knock the headunit off its mounting bracket. The downside of this happening is that the unit will get cracked, scuffed and marred if it hits a solid surface such as asphalt. This actually happened to me and, as a result, a bit of the silver plastic trim has broken off. The display is still fine and it works just like before. Its partially my fault for not being as careful as I could have been; however, the headunit can definitely be build a bit more rugged (probably at the expensive of its current elegent look).
So far, neither of us have experienced any of the issues mentioned by other reviewers here. I could see where it could get real frustrating if one of the functions just suddenly quit. Its important to moisturize the contact points on the HRM strap to get a good clean reading. I picked the computers up on the web for $84.99 and I think the BC-1909 is a killer unit for the money.
By the way, this unit kills the Cateye V3 when it comes to legibility of the headunit data. Its also $50 cheaper to boot.
There is a very clear and concise video on Youtube from Sigma Sport on how to install this unit. The unit comes with all the necessary mounting hardware including a temporary install option (using O rings) and a permanent install option (using zip ties).

So, after reading some of the other reviews on this unit, I felt obligated to toss my own in. I picked this up with my shiny new Cannondale Synapse, and I have thusfar been pleased. The ONLY issue I've encountered has been with the speed sensor being on the rear wheel.. (I ride my bike on the trainer a lot currently, and wanted it on the rear wheel because of that) - I actually found that moving the speed sensor from the chain stay to directly next to the cadence sensor fixed that issue for me. I'd imagine if I had installed the sensor on the front fork (as most speed sensors are) that I wouldn't have any issues at all. The heart rate and cadence functions work just fine for me as well, and I haven't experienced them cutting out. All 3 of the sensors take maybe 5 -10 seconds of activity to sync up properly, but after that they're pretty solid.
As far as magnet distance, I've not had any problem with that at all, the only issues I had were with with the aforementioned wireless transmission. If you read the directions that come with the unit, you can get an idea of how you need to install the transmitters to get them to operate properly.
Again, I'm nothing but pleased with this unit for the $70.00 that I paid for it. if worse really came to worse, and the speed sensor started acting flaky on the rear wheel where I have it positioned now, I'd pick up the wired speed sensor for my road bike, and toss the wireless receiver on my secondary bicycle and take advantage of the 2-bike mode of this computer.
