Garmin Bike Speed Sensor 2 and Cadence Sensor 2 Bundle, Wireless Speed and Distance Sensor and Cadence Sensor with ANT+ Connectivity and Bluetooth Low Energy Technology, Black

I bought the speed and cadence sensor for my spin bike, so for those asking whether or not you can use these on a spin bike, the answer is yes provided that there is enough room for the speed sensor to fit on the flywheel mount at the front of the bike (see pictures for reference).Overall, you can't fault the product. It's worked great for me, is accurate as far as I'm concerned, allowing me to track data from my workouts. One thing to note, you NEED to do your research into what this thing can pair up with...I've seen so many reviews on here saying that it's not pairing...that's down to user error, not the product itself. Follow the instructions, and videos on youtube to see best ways to pair.The way I use it: I have a Garmin Vivosmart4 (basic fitness watch, a bit like a fitbit) and thus already use the Garmin Connect app. You can easily pair the Speed Sensor to the Garmin Connect app by just going into the 'Devices' settings. (Note that because you can't see live workouts via the app....you will not be able to pair the Cadence sensor to the Garmin Connect app!) Your speed sensor data (distance, highest and average speed etc) will just be uploaded as an activity when you finish your exercise. In order to see the live data, I use a free app called Cadence - on this, you can easily pair both Speed and Cadence sensors (as well as a heart rate monitor if you so wish) and have everything displayed on one screen. This will show your distance, speed, RPM etc. (I love this app as you can also switch between indoor and outdoor cycling, so perfect for me on a static spin bike).Relatively quick and easy to install (cadence sensor strap a little fiddley but didnt take long to secure) and are now tightly in place. The cadence sensor comes with 3 different size plastic straps to go around the pedal, I had to use the biggest. The speed sensor comes in a silicone case so the strap is stretchy...that being said, I had to be a bit creative with an elastic band as on the spin bike the fixture is a lot thicker than a normal bike. Both sensors automatically switch on when moved so no need to fiddle around before each workout.Overall, can't fault it. The product is definitely worth the money compared to cheaper alternatives on the market, materials feel quality too.Hopefully the review can help answer some questions others have had!

I am using this on an indoor exercise bike. Installing couldn't be easier, both attached to the pedal crank arm. Cadence sensor paired flawlessly, the speed sensor unfortunately came with a flat battery. Annoying as this meant spending time searching for a cr 2032. Once new battery installed this also paired flawlessly.Setting the wheel size can be tricky. I knew that at approx 65rpm I covered 2km in 5 minutes. 65*5=325. 2000m / 325= 6150mm. Setting this as the wheel size ( circumstance not diameter) saw this within 2 seconds at 2km. Fine tune another time.UpdateSpeed sensor did automaticially switch on when pedalling. Moved the speed sensor from the crank arm to the bottom of the crank, ie in same relative position & orientation as if fitted to wheel hub, however this did not resolve the problem. Swapped to road bike, still not switching on. Removed & replaced battery the sensor then came to life. Contacted Amazon who contacted Garmin on my behalf. Upshot new speed sensor on way. Great service, in resolving this frustrating situation.

Bought the other one and the speed didn't work, sent back and bought this one. The cadence is correct according to the indoor bike monitor but the speed isn't. Easily correctable by editing the distance by hand measured by the monitor and then the speed matches. I have the Garmin instinct 2 and it picked up both sensors in a second or in one spin of the wheel. Most important held the connection that the first one didn't. A great gadget makes me be able to use both indoor and 'normal' bike ride counters on my watch and transfer the data on Garmin connect and this one transfers the kcal on my calorie counter.I have put the speed sensor on the axis of the pedal which is the reason for the difference in distance from the bike's monitor

Truth be told, I bought these Garmin sensors because I wanted them. I didn't need them - my £9 speed\cadence sensor from Aldi has done a perfectly good enough job, reliably for the last year. But somehow I convinced myself of th convenience of these that could easily be moved between my bikes, even though buying another one from Aldi would have been cheaper and easier.That said... I love the fact that these from Garmin don't require any magnets or aligned sensors, and they're far neater than the cheaper alternatives. They're so compact that you actually can't really see them, especially the case for the speed sensor which wraps round the back wheel hub.I've connected them to my Garmin ForeRunner 935. When I first tried to get them to connect, I couldn't get the cadence sensor to work, so I took the battery back off in case there was a plastic battery blocker. There wasn't. And when I put it back together, I either broke something or didn't put it together properly because I couldn't get it to power on for the next fourty minutes. Eventually, I managed to put it back together in a way that aligned the contacts and it now works fine. I'm not looking forward to replacing the battery though. This is the reason for the lost star in the review.Connectivity is reliable and accurate. Never any delay or lost moments.In hindsight. I will use these for races, and I'd have extra confidence in these kind staying put, as they don't need to remain aligned with other sensors. It'd be easy to accidentally knock them out of place mid-race, so perhaps the extra money is well spent!

Product connects to my Garmin watch easily and quickly, which reduces stress. Product is good value for money, looks good, and does what it says it will. Would recommend.

Good
