CooSpoCadence & Speed Sensor for Cycling, Wireless Bluetooth & ANT+ Bike RPM Sensor for Cycling Computers, Compatible with IP67 / Rouvy / Zwift / Peloton / Wahoo / CooSporide

Followup to followup review----I reached out to the mfg about the broken ear causing the sensor to fall off, and preventing it from being mounted. After verifying that I mounted it correctly, they quickly send me a replacement. I will wrap the sensor with electrical tape just to be safe.Followup review----On one of my ride, I glanced down and saw my cadence being blank and noticed the sensor not there anymore. I saved and replayed my ride to see where the cadence stopped, rode back 3 miles and found the sensor (didn't look for the backing or strap as it was raining). Turns out the one of the ears where the silicone band hooks onto broke off, just as I had concern about. Now I have to wrap it with tape after mounting so it doesn't come off.After less than 500 miles, that's pretty fragile. It might be the reason I lost the original one. Dropping from 5 stars to 3.One thing I also noticed is the cadence update is a few seconds behind, so if you mount this on your stationary bike and want to see your peak cadence, you are not going to get that.Original review----This is a replacement for my last Coospo sensor that fell off my crank. The replacment works fine as expected. I do like the fact it has ANT+ and BLE, so it could send data to my bike computer and phone at the same time. Weird that a 2 pack cost more than 2 single pack, which is what I purchased. I read you can't pair both at the same time via BLE, but I using another brand's speed sensor, which is no problem.A couple of minor issues. The form factor is squarish, which makes it stick out when attached to a hub or to my old school crank. This time, I mounted in between the spider on the chainring side so nothing would bump into it (unless a dropped chain does). The other thing is removing the battery to change between cadence and speed sensor mode. I've had others where there is a tiny switch internally. By the time the battery needs to be changed, I would have forgotten if the blue or red light indicates it being in cadence mode. I would find out there is no cadence reading, then have to go into the app or bike computer to see what type of device is discovered. Probably have to stuff the instruction into somewhere obvious, which I would not remember 8 months down the line.

Bought my first Coospo Cadence Speed Sensor based on recommendations from a few friends, the positive reviews here on Amazon and compatibility with my phone riding app. Installation as a speed sensor was easy and flawless. The longest part of the install was getting the sensor in my front wheel hub with my carpel tunnel plagued fingers! All in all up n running in less than 10 minutes and WOW what a nice, even speed rating in my app. Before the Coospo Sensor the app would use GPS satellites to calculate your speed. Lagging real changes in bike speed and bad coverage in wooded areas are gone AND forgotten!Shortly afterwards I purchased a second sensor for Cadence functions, and like the first the install was flawless. A few months after the second purchase I ran into a small snag that was bothersome. Sure it was something on my end but couldn't figure it out. A message into the Coospo folks and I got a near instant reply! A few eager back and forth messages and my issue (yes it was MY issue) was promptly and politely resolved. Talk about after-the-sale-support, not only did Coospo step up to the plate but they KNOCKED IT OUT OF THE PARK!What a great company, great products and spectacular staff to assist their customers!

So far so good! Easy, secure installation with included bands and rubber plates. No problem to adjust speed vs. cadence mode. Simple pairing with watch and data seems accurate. Only initial question is why I got two sensors detected on watch: Quick search showed that one is ANT+ (numbers only) and the other was Bluetooth (started with a "B"). I disabled bluetooth connection and went with ANT+ only for my watch, so I can use Bluetooth for other devices if needed.

I have had the CooSpo heart rate monitor with great success and usability. So I ordered the speed and candence sensors. They arrived quickly. The picture directions are clear about the install. Setting the modes between speed and candence is as simple as removing and replacing the battery.The connection to the Wahoo Bolt was quick. I connected using ANT+ since it had the strongest signal at a distance. The Bluetooth connection did show a weaker signal. Also Bluetooth in general uses a crowded spectrum so living in a urban population, the use of ANT+ is better.During my first rides they work great! The speed sensor wakes up at about 4-5mph after that it's accurate from 0 on your ride. There is a latency I noticed of 1-3 seconds in the data to the head unit.These sensors replace the Wahoo BlueSC and are far better than the magnet sensors.For durability, I am not sure how long the rubber neoprene bands will last. They give you many extra bands. I'll update my review if I have an issue.Great buy, easy to use, excellent value! I would recommend them.
