Product Description
The Sigma computer for dedicated cyclists. The "L" in the BC1606L is for the "smart" back light. The cadence functions (current and average) provide valuable training data for efficient cycling both on the road and in the woods, and can be turned off completely when not in use. The count down timer is perfect for crits, cross, or racing against the clock. This model is packaged with a 120cm rear harness, ideal for indoor trainers. Handlebar or stem mount.

I just bought this item. It includes two harnesses. One for the front wheel and one for the rear wheel. It also includes the optional wired sensor to measure cadence and of course the bike computer itself. I am please with the unit so far and I installed it on the rear wheel of my bike that is on a Kurt Kenetic trainer. It works well for both speed and cadence. Now I can judge the kind of effort I am using and can up my game as time goes on. The only problem was that the install instructions leave a lot to be desired. I figured it out but it took about an hour for the install. The package also does not come with a list of items included in the box either which was a little frustrating. These were not really big problems but Sigma should address them for the future. I recommend this unit to anybody who wants a bike computer with a wire rear wheel sensor.

We've had this a few weeks. I purchased for my wife's bike so she could use it with the indoor trainer. This was one of the cheapest ones I could find that would work for the rear wheel. It also has the cadence monitor. Pretty easy to understand, not too difficult to set-up. It has a back-light on it, so once you press a button it will light up for a few seconds. Probably could have used a couple more zip-ties with it, but I had some.

Just got and installed this computer today. couple things you should know about it:
1) the backlight is like an indiglo watch. when you have it "on" (really "on" means "enabled") whenever you hit a button it lights up for a few seconds. It does not change modes or whatever unless you hit the button again which is nice.
2) other reviewers have rightly noted that the refresh rate is rather slow. If this bothers you, this is not the computer for you. Backlight was more important to me than anything else as I ride a lot after dark. If I don't have a backlight I might as well just not have a computer at all.
3) the computer comes with two wheel sensors; one front wheel and one rear wheel. The front one *always* reads as "Bike 1" and the rear one as "Bike 2." There is no way to change this unless you want to get into disassembly, glue, soldering, etc. There is only one cadence sensor and one wheel magnet in the box so to fully install this on two separate bikes you would need to purchase another cadence sensor and wheel magnet.
I didn't have any problems mounting this with the cadence sensor on the stem of my old bike. I suspect that the problems others may have had was because they had large threadless stems; I have an old aluminum quill that is rather slender. You might have to gently bend the connectors to get it to work on a larger stem. (I don't have a whole lot of handlebar real estate on my bike...)
that's about it. I'll try to remember to check back and comment on durability in a while, but I suspect that this is being closed out and replaced by a newer product, because of the very low price so by the time I get around to it it may no longer be available.
edit: I see that this computer is still available... it's still on my bike, too. Still working fine and on the original battery. Have not discovered anything about it that wasn't already covered in my original review. It's just working and doing its thing, and since all I really wanted was something to tell me appx. how fast I was going, how far I'd gone, and how fast my legs were turning, it's met my needs perfectly.

Great bike computer at a good price.
Well, what can I say? It works and it's relatively cheap. The buttons and overall usage take some getting used to, but the readout is awesome and the backlight comes in handy. Read more
