COOSPO Bike Cadence Speed Sensor BK467, Bluetooth ANT+ Cadence Sensor for GPS Bike Computers, Tracking Cycling Speed and Distance RPM, Compatible with Zwift Wahoo Peloton Openrider Rouvy APP

Why did you choose this product over others?:Connects to my CS500 with no issues and has good battery life.

I just bought a new bike and wanted to fit speed and cadence sensors that would connect to my Garmin VivoActive 5 watch, so that I could accurately track my activities. These are great! Nicely packaged with rubber “bands” in a variety of sizes and two rubber backing pads - one flat for the cadence sensor and the other with a curve on it to help it sit snugly on a wheel hub. The instructions were clear and simple. Open the battery compartment, remove the thin plastic disc, replace the battery. LED flashes when battery inserted - blue representing Cadence setting, then remove and replace battery a second time and it flashes red to represent Speed setting. Once done they fitted onto the crank (cadence) and hub (speed) easily with the rubber bands. (There is also a spare of each of the three sizes just incase, which is a nice touch).Adding to my Garmin was simple - Settings, Accessories, (I have Auto Discover set to on), Add New, Speed/Cadence and it starts searching for the sensors. A quick spin of the crank and wheel activates the sensor and the watch “sees” it. You’ll add the speed and cadence sensors one at a time since they are separate units. Nearly done! You just need to configure the tyre circumference. Under Accessories you’ll see the speed and cadence sensors listed. Tap the speed sensor entry, and look for the wheel size option. I manually entered mine (no idea how the Auto option works!). You can either try and measure the outer diameter of the tyre and multiply by pi (3.14ish) or lay a tape measure out on the floor, place the bike with the front wheel valve at the 6 o’clock position and at zero on the tape measure and carefully push the bike forward along the edge of the tape until the valve has rotated once and is in the 6 o’clock position again. Take the measurement there and pop it into the watch. (My 700c road tyre was 2136mm just as an idea)Now you’re good to go! Just start the Bike/cycling activity on your watch and it’ll automatically detect the sensors as soon as you start to move.Accuracy looks pretty spot on as I used it on a track which is exactly a mile, and taking the best line around the track, after 5 miles, it showed the mile marker only around 10 feet before I crossed the start/finish line (and to be fair, I probably ran a little wide on a few corners, so the variance was probably down to the line I was taking, not the accuracy of the sensor!).All in all, very pleased with all aspects of these sensors, and they are quite discreet on the bike since they are two sensors with accelerometers and don’t rely on magnets attached to spokes/cranks to activate them.Photos show cadence sensor on Shimano 105 crank arm, speed sensor on Mavic rear hub and the spare rubber bands. The large was just right for the large diameter of the rear hub and the small for the crank arm.6th Feb 2015 - Update - I was so pleased with these that I just bought the Coospo HRM chest band, which also came nicely packaged, was easy to set up and appears to work very well!

Bought this sensor to use as a speed sensor on the turbo trainer. At £14 it's one of the cheapest but does what I need. Only had it a few days so can't really comment on battery life etc.Only issue I have is that I can't see an led to indicate the mode. But it connects fine with BLE and ANT+

Easy to set up and use with major fitness apps

These work well and quite accurate.

I used this cadence sensor on 3 cycle rides before the arms snapped mid ride and it fell off. Luckily I noticed and picked it up, but it's now completely useless. Contacted Coospo and have been ignored so can't even get a refund or replacement. Don't but this!!

Arrived quickly and work well with the wahoo programme and hardware

Had my sensor set up for cadence and it was very accurate for the ~100km it lasted until it fell off!I had my sensor securely attached to the inside of my crank arm with both the rubber padding and the tight rubber bands, and yet it managed to fall off during a ride.Good value for money and easy to connect to bike computer/mobile app, just make sure you attach it very securely!
