Product Customer Reviews

I purchased one as a flyer. The user interface can be somewhat difficult to navigate. I found that the stats that the cyclometer was showing me did not match what my phone and GPS were reporting (i set it to my wheel specs). If you're looking for something super accurate, I would look elsewhere.
Thank you for taking the time to share a review on our product. I am very sorry to hear about your bad experience with our product. It seems that your product has a defect since it should normally provide accurate results.

Easy to install and pretty accurate. Was a little concerned about mounting the gyroscope on my zipp 404s but found the unit remains stable and unobtrusive.
Easy to use & setup clear visible indications.
Easy to install and easy to set up. Nice clear readout. Hard to know how robust the mounting system is but assuming it's fit for purpose I am pleased with this.
gets the job done. easy to operate
Works perfectly, don't waste your money on more expensive products
Works well. Easy to set up
Brilliant connection wirelessly and super accurate .. Worth every penny
The first time I purchased the product, I lost the display unit, cursed myself, and thought I'll have to buy a new one. Fortunately, Decathlon, replaced the item for no cost. I set up the unit following the incredibly confusing instructions - pictures only - then found there was no response, ie. it wasn't measuring the speed. I asked Decathlon and their suggestion was to change the battery, which at the time I thought unnecessary as it is a brand new product. But, before, I went back to the store for assistance, I did change the battery (hub sensor) and voila, it worked. Furthermore, upon reading the many negative reviews of this product, I found that the mounting of the device is poor, and perhaps, I shouldn't be hard on myself for losing the first one. I think next time I would visit a cycle shop, who backs their product and has better quality brands. Clothing at Decathlon I would like to try. By the way, I've found the staff at Decathlon to be very helpful (Box Hill South store).
Has not worked since purchase. I have sent three (3 !!!) emails to Decathlon and received NO response - NOTHING.
Really good large display covers needs ( really do you need Temp as on some) magnet sensor fits on hub so no unit on forks (really good idea) I have a Cateye on my hybrid I’m swapping this on to it. Bit of a fiddle to set up but it does make sense (pictograms for instructions) . Very pleased
I purchased this odometer for a long distance bicycle tour. Setup was pretty easy and it looked promising. However three days into my trip it stopped working. I replaced both batteries but unfortunately lost my overall trip distance. From that point it did work sporadically but certainly not reliable. Now I'm home, the numbers do not fully display. Very disappointing.

After initial set up, the unit worked as it should for about a week, then it suddenly stopped. As others have mentioned, I assumed that the unit was faulty and was about to return it when it dawned on me to check the battery in the sensor. Well, it was dead so I replaced it and the unit is working again. It is disappointing that I needed to replace a battery after one week of ownership but at least it is working now.
This is the perfect, cost effective tool that I needed. The display shows the basic data I want to see... speed and distance, plus the option to view other parameters like elapsed time, time of day, even temperature (handy to note in my Strava record).
