CooSpoBike Cadence Speed Sensor BK9,Bluetooth 5.0 ANT+ Cycling Cadence Bicycle RPM Sensor,IP67 Waterproof & 300H Battery, Compatible with Rouvy/Zwift/Peloton/Wahoo APP/GPS Bike Computers

I found this works great, it wakes up and connects without issue after a few rotations of the bike crank. Readings are accurate compared to my other sensor which cost me more. Supplied with rubber backing pad and two sizes of bands. Overall very happy with this.

This cadence sensor weighs almost nothing and attaches straightforwardly to my bike's crank arm with the supplied rubber strap. It works perfectly when paired with my Garmin Edge 130 Plus and costs half the price of the equivalent Garmin sensor. So far I've found nothing to dislike about it.

Very pleased with this product.

I needed a sensor for my trainer in the garage! This works perfectly to get speed and distance! It paired easily with my Garmin edge! Great buy!

I love the sensor, do not love the retention system. That's pretty important, because at high speeds it's either going to hold tight, or go off in search of adventure. I was able to use this successfully w/ Strava, and it tracked very faithfully with no loss of connectivity. But after about a week it fell off somewhere :(

This review is for both the speed and cadence sensor. I bought them together, installed and tested them at the same time, and if Amazon takes me to the same page for both when I try to write reviews.My gear: Trek Checkpoint SL5, Shimano GRX RX600 170mm crank, Bontrager Paradigm SL wheels with 700x40mm with GR1 Team tires. Garmin Vivoactive 4 watch with the Garmin Connect app.Install: For both sensors, remove the battery, pull out the plastic tab, then put the battery back on. The speed sensor had a silicon case with the strap built in. I mounted that on the front wheel in a few seconds. The cadence sensor comes with two different size straps, and a little silicone backing. This took a little longer to find the right spot on the crank where it would have enough clearance from the frame when I pedaled, but still very easy.Setup: This was really simple with my Vivoactive 4. It was about 4 clicks total on my watch for each sensor, and my watch found and connected to both sensors in a few seconds. They go to sleep when not active, and are found and connected again immediately when you turn the wheel and pedal.Next step is to ride. I don't have a scientific method to test how accurate they are, but they seem to be in line with what I know my riding ability is right now. You can see in my horrible stats from the screenshots I attached that I'm still recovering from a car accident a few months ago, so my speed and cadence are both pretty low. The speed matches what my Garmin watch was calculating on it's own from GPS before I had the sensor connected. I don't have any old cadence data to compare to.So, easy to install and set up, and as far as I can tell the data is accurate. The only question I still have is how long the batteries will last, and I'll just have to wait and see on that.

This was really easy to install and it paired up easily with my Pendleton app

Los sensores se desconectan del garmin, el sensor de velocidad no marca la velocidad lo que hace que no registre el ejercicio.
