COOSPO Cadence and Speed Sensor, Bluetooth ANT+ Wireless 2 in 1 RPM Bicycle Cadence Sensor, Bike Speed Sensor for Cycling Computer, Compatible with Zwift/Wahoo/Peloton/Openrider/Rouvye APP

Like others I was a bit sceptical of this device. These kinds of things are usually a nightmare for connectivity and even if the hardware works, the app is usually rubbish...However, this was really easy to set up. Essentially it is two magnetic sensors that count the frequency of a magnet passing by. One magnet goes on the crank and the cadence sensor counts the RPM - how fast you're peddling. The other magnet goes on the wheel and the speed sensor counts the number of revolutions and converts that into a rough speed. The hardware is very simple and works well.The instructions are pretty good and clear enough, and the tolerance on the magnets is big enough that you don't really need to line everything up exactly.The connectivity is also good. The firmware is a standard Bluetooth/ANT+ Speed and Cadence Sensor, which is a defined standard so it will work with pretty much any app or brand out of the box. Three spins wakes the sensor up, and then it appears immediately on my Garmin watch (ANT+ connectivity) and iPad (Bluetooth). There are no rubbish manufacturer apps required. It just connects straight to your app of choice (I've used Wahoo and Zwift with good results).I don't actually own a bike - I bought this to use with a indoor exercise bike since I wanted to connect to apps without shelling out £600+ for a Bluetooth-connected exercise bike. The cadence sensor worked well from the beginning - I just put the magnet on the crank and stuck the sensor to the casing of the exercise bike.I did have issues with the speed sensor but to be fair, it's not designed to be used with an exercise bike and I was able to sort it out. Since it's expecting to be mounted to a bike wheel - which is geared to spin much faster than you're pedalling - the speed sensor was only picking up 60-80 rpm which translates to a really slow wheel speed (about 10 kph even when I was pedalling furiously).What I ended up doing was attaching two of the included magnets at 12 and 6 o'clock either side of the crank axle (on the bolts that connect the axle to the belt wheel on my bike). Now, with each turn of the pedal, the cadence sensor is triggered once by the magnet attached to the crank, and the speed sensor is triggered twice by the magnets on the belt wheel - as if it were a bike wheel geared at 2:1. That gives me a decent speed whether I'm recording on my watch, with Wahoo, or using it for Zwift. I'm amazed that this hack works so well but I think that's a testament to how good this sensor is - it works well even for the things it wasn't designed for.So top marks all round - a cheap and easy alternative to a smart bike!

Arrived quickly, 10 minutes to fit on my road bike that is set up on my turbo trainer. I switched my Garmin Edge 130 on, it immediately paired with the CooSpo cadence and speed sensor and worked seamlessly on my first session. Does exactly what it says, remains to be seen on the longevity of the product but it appears well made and as good as the other more expensive products on the market.

Works as advertised. East to pair with Suunto watches. Cable ties could be stronger.

Seems ok. Installation is quite straightforward, and if you are worried it might be nicked, it's pretty discrete, so unless people know it's quite unlikely. Sadly, if someone does know what it is then it's a fairly easy one to walk off with so tie it down well!Works with my 107, although I still don't know why I need to know cadence, it's there if I ever want it!Early days, if this post is still the same 6 months down the line, then you know it's still good!

very accurate cadence can't use the speed part as I have a fat tyre bike so doesn't work but still pleased with it

This simply didn’t do what it was supposed to.Terrible instructions for setup and came with a flat battery. The magnet screw for the spoke sensor was loose and couldn’t cope with the weight of more than 1 magnet.Bought a new battery and eventually managed to get this to sync with Zwift but wouldn’t register more than 6mph despite significant effort and high cadence.Seems like a good cheap solution, but don’t waste your money!

The sensor are accurate and worked well with the app and with zwift. But after I got a new bike I realised that the design is rather flawed as you need a round bar, crank are running really close to the sensor and spokes that are perfectly sized to allow the speed sensor to be on them and still have enough clearance from the sensor to spin but not too much so that its not close enough to register. As this is the case and the product isn't necessarily faulty I'm getting the ones from moofit.

Good price for a dual sensor. Easy to fit with simple connectivity. Paired to head unit and Garmin watch easily. Accuracy appears very good.

Habe mit dem Gerät nun 1200 km auf der Uhr und bin zufrieden. Bei meinem Fahrrad war der Anbau etwas schwieriger, weil zum einen die Kettenstrebe zu dünn ist, der Abstand vom Pedal zu groß und mein Pedal auf der Rückseite eine Aussparung hat. Das konnte ich aber mit einem Distanzkronkorken lösen.Am zweiten Tag musste ich das Gerät einmal neu koppeln, danach lief es aber störungsfrei.

Convient parfaitement à mes attentes, se connecte facilement avec compteur LEZYNE.

Smidigt med kardan och hastighet i samma sensor, men det ställer lite krav på måtten på cykeln och vevarmarna för att kardanmagneten ska komma inom 12mm från framänden från sensorn, samtidigt som den justerbara armen bak på sensorn ska komma 12mm från hastighetsmagneten (på en eker). Jag fick bygga ut ett litet torn bakom min vänstra vevarm, så att magneten skulle nå sensorn.Funkar finfint med Wahoo på iPhone, sensorn vaknar snällt när man rullar igång. Smart inbyggd testfunktion med olika lysdioder för de båda sensorerna (15 minuter efter batteribyte). Batteribyte är lite småjoxigt, med luckan bakpå sensorn; endera får man lossa sensorn eller pilla lite fingerfärdigt genom ekrarna.

Très bien se connecte parfaitement au GPS du vélo quel que soit la marque et tout à fait compatible que ce soit sur un vélo route ou un VTT

Funciona perfectamente sincronización a la primera con Garmin. Muy contento instalación sencilla sin herramientas. Un cortaúñas para cortar las bridas ha sido la única herramienta que he utilizado. El precio sin ser un chollo me parece más que correcto.
