Customer Reviews

Cool little bike computer, Installation can be tricky.
This was my first bike computer and I'm happy with my choice. It does everything it's designed to do quite well. There is a little bit of a learning curve as far as navigating through its options/functions but once you get it there no issue at all.

Installation was a little more involved then I thought it would be and I am very mechanically inclined. Nothing your average DIY'r can't handle just some interesting things to deal with like placement of the magnet and dealing with, for my install anyway, an overly long sensor wire. You have to get a little creative to keep the wire secured and out of the way of moving parts.

The first mount/sensor wire assembly that I received with the computer was faulty. After much remounting and head scratching I called the US contact for Sigma. He was very helpful and told me that while every computer is tested for operation the mount and wire assembly are not. He sent out a replacement mount/wire (at no cost) and once I swapped it out the computer worked perfectly. I don't I think I broke the wire on the first one as I was extremely careful with the installation but just in case, be careful as it is a small wire and you have to make several turns and twists to get installed.

The manual is one of those international mutli-language picture books. I hate them but if you spend some time deciphering it before you start you can get it done. As one of the other reviewers stated, getting you tire size right is critical to the accuracy of the computer. So spend a few extra minutes here and actually measure the circumference. Using the chart in the manual will get you close but not exact.

Once installed the combination of the double sided tape and rubber ring used to mount the computer to the stem or handlebars is actually quite secure. I have no fear of it coming off in normal use. A rubber ring is also used to mount the wheel magnet sensor to the fork. No tape is used here, probably to allow easier adjusting but doesn't feel quite as secure because of this. I've had no problem but now that I have it positioned properly I may add some d/s tape or a wire tie to lock it in place. The spoke magnet locks on very securely but follow the instructions closely on this part.

I really like this product and the customer service was excellent. If it was stolen or lost I would by another immediately. Have fun with it.

Does everything it is supposed to.....
That's it, you need to read the fairly straightforward manual and install it correctly, but the bang for the buck here is teriffic. The wire is unobtrusive and I guess that the "unwired" version would have two batteries; one in the sending unit that seems to me would take more power and maybe go out quicker. My guess only.
If you have a bike path with mileage markers you can tweak the unit to your bike by changing the wheel size that you input in it, making it very accurate.
I find its more fun to know your speed, distance, average speed, etc., it gives you something to shoot for on your next ride. Plus it weighs about nothing; you could wear thinner socks and make up for it.
Have fun.

magnet fell off
I just got one of these, and right away had a bad feeling. I didn't get everything it said I would in the manual. I have bladed spokes and there was supposed to be a 'pad' but none came. The buttons didn't have a very good feel to them, like I could push them and nothing would happen. Then when I tried to install the magnet, it didn't attach securely enough. I waited and got someone to help me, but the problem wasn't me, it was the way the magnet was designed. If we tightened it to stay on my spoke, the nut just got pushed out and fell on the floor. So we put it on as securely as it would go, I rode once with it and it worked, but the second time I used it, the magnet fell off and got lost. I think there is a problem with the buttons too, they don't always seem to work, although I didn't get a chance to use it enough to be sure if maybe it was just me getting mixed up. I'm hoping to be able to return the computer and exchange it for a different model.
