used for 2 to 8 weeks Perfect for most people, easy to set up although the sensor can be awkward to get right. The buttons also don't feel as crisp as my last one but work perfectly well

plastics not sold separately

good for the money

plug, unplug.... times later; normally rotten.

used for 1 week or less after a period of use; the mounting plastics got old. it's normal, ok. But you don't sell them separately. I mean; when the plastics are broke, do you sell extra for the owners?

Doesn't seem to be picking up a signal


  (United Kingdom)


2 5

I've been setting this up today. I've followed the instructions; the little magnetic button is about 3 - 4 mm from the receiver on the front wheel; a green light comes on the receiver when I press the battery test button, and the computer itself seems to be behaving normally. However, nothing happens when I cycle. The computer isn't acknowledging anything. I also tried spinning the wheel with the computer held close to the wheel; still nothing. Any ideas what I might be doing wrong?

I'll change the review score if I can get it working.

Response of the brand

Dear sir,
The battery on your emitter may be faulty.
Either pop into your local decathlon store and they can swap the batteries over for you FOC or contact our customer team who will find the quickest solution to get you out there using the computer.

Pleasant Budget Surprise

Easy to set up and good aesthetics.

40-49 years old    Man

used for 7 to 12 months I purchased this bike computer a year ago and at different times used it on two road bikes and my hybrids.

Personally I found the instructions reasonably clear, better than most of the bike computers I have had in the past, just remember to enter the correct wheel and tyre size. The instructions include a graph to assist.

I noticed others have had problems fixing the computer to their handlebars. I have had it attached to three different stems, all oversized without problem. The elastic type band does need to be stretched quite far but it results in a tight fit. The sensor sits on the leg, just as a safety precaution I also used a zip tie. Whilst sitting on the front fork leg it has a consistent signal.

I have recently purchased a GPS speedo and ran the two side by side on the first ride. I was surprised how accurate my "budget" B'twin speedo was. It gave the same readings throughout.

The B'twin is now on my commuter bike so is still getting used, easy to swap over, just don't forget to change the tyre size settings. It's now even cheaper than when I bought it, so a bit of a bargain. It looks more expensive and other bling Mamil riders have commented on it's looks. It's also been used in the rain with ill effects.

I ride every day and recommend this as a great first speedo.
