Sigma Sport

I've put some miles onto this Amazon Warehouse purchase, so here's my review.The pluses:- Once you find unfold the giant sheet of instructions and find your preferred language, it's pretty easy to setup. The only tool I used was a flat screwdriver to help slide the clip onto the spoke magnet.- It's wireless and it had no issues with it talking with one another. Sure, it'll be an extra 2032 battery to deal with in the future, but the included ones were not cheap generics and it claims 1.5 years for the transmitter (and 4 years for the computer).- Auto starting and stopping. It also knows when the bike is in transport mode too; the computer's accelerometer moves, but not the wheel sensor isn't.- The various animations are cute. I went with the turtle.Neutral:- No real time clock, which might why the battery can last a lot longer. It'll do speed, distance, riding time, and total distance -- and that's about it.- How durable are the silicone bands? The wheel sensor does have slots for zip ties, though, so that can be added for some extra security.The nit:- I'm guessing that the LCD uses a reverse polarizing filter, hence the white (light) on black (dark) display instead of the more common dark on light. As noted in another review, this makes it harder to read. Different versions have different displays, so take this into consideration.Overall, not bad but not outstanding either, so 4 stars.

This model turns out to have a black background to the display. Not sure why. I may get used to it but seems harder to read. Most of the other models have a normal display. Also there doesn't seem to be a normal clock function. Unless I just can't find it but really don't see any mention in the typical "every language known to mankind 2 point font" instructions. There is a trip time function. The structure of this design seems sturdy enough and the design styling is fun.

Keeps adding miles after I stopped. Other than that it’s ok. Last time I rode it was less than 2 miles. It went from 100 mile to 149 total miles. Put it on my 9 year old’s bike.
