500 Belaidis ciklometras

I had this product for several years and never had any problems with it. Recorded accurately and was robust enough for general cycling. Unfortunately, after an accident, the sensor attached to the forks was lost and it does not seem possible to obtain a replacement. Perhaps somebody knows otherwise.

I liked the price and the in store comparison sheet said it showed temperature which would be pretty handy for mountain biking. It doesn't show temperature. The sensor generally needs to be lined up with the magnet EVERY ride. Even if it's just been in the garage. When it works it's decent enough. Normally pretty close to Strava. Went over the bars the other day and broke the little bit of plastic that joins the unit to the mount. Currently improvising a mount with the rubber bit that goes on the back of the mount, double sided tape and a silicon band. The whole thing really isn't robust enough for mountain biking even when I manage to stay on the bike.

I got this two weeks ago and have used it only a few times on my bike. However, while I was cycling today though some bumps, the computer fell of and the plastic pieces at the back of the main body was broken. The design is clearly flawed and the computer was never securely connected to the holder. Then I called to ask if this situation is covered by the warranty, only to receive an ice-cold "no", referring to my problem as my own "mistake." What can I say about this fragile product with awful build quality and the poor customer service unlike the advertised rosy "365 day return" ? I've been a loyal customer for Decathlon for a few years and because of this incident I will not step into another one of Decathlon store's door. Congrats Decathlon, you just lost another customer.

I now need to take this back into the store, having set it up it fails to connect regardless of having reviewed the fitting instructions on you tube to ensure it’s not user error
I’m sure that when it works it’s a great bit of kit just need it to work first

On a road bike with "fat handlebars" it is very difficult to get the unit attached as the expanding band is not intended to reach that far. But it can be achieved - just - after a lot of effort. No point doing the set up until it's attached to the bike, as it's far too easy to keep pressing the reset function, meaning it has to be re-done.

But, after all that it did not work - i.e. the screen works, but does not pick up the speed from the remote. So it's going back to the store.

On my second of these - the first was on a bike which was stolen and I've just managed to lose the pick up sensor on the new one. Shame that you can't by this as a spare part.

I did buy 2 sigma wireless cyclometers that died quite soon. This Btwin one is a lit more robust, easy to use and excellent value for money.

This is the forth btwin 500 cycle computer not because I have had issue but they are excellent. We have a family of four bikes and each one has one fitted. In the past I have purchased big branded cycle computers both wired and wireless but none has been so reliable as btwin 500. They are very accurate too . Great product, great price

Good piece of kit, have reset back to zero, however when I cycle I get no distance tracked

I've had several other wireless bike computers and always been able to get them set up and working fairly quickly, but I found this one to be fiddly to install and sadly it is working.
I've read other reviews and seen comments about getting the magnet and sensor fairly close, so I've ensured that they're practically touching but the unit still won't work.
One of the Decathlon responses I read to a comment said that a new magnetless design is being released, when will this be?
It looks like I'm going to have to remove the unit and return it to the store, which means a fairly long drive. Not overly happy.
