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

The units are quickly recognized by iOS and Android. Wahoo also recognizes the devices. They are initially “seen” as cadence/speed. Android and Wahoo identify the Ant+ signal and the setting of cadence OR speed that is set when placing/replacing the battery as directed in the manual. I found it easiest to pair one at a time with the other “asleep”. Pairing the speed first was the easiest way to keep the sensor asleep while pairing the cadence, but the pairing can be done in any order before installing. Just remember or mark them to distinguish as they appear identical. iOS will pair with both, but in use will only recognize one or the other. The ble id does not allow me to use both at the same time. I attempted to pair them as one does for multiple earphones, but got wildly inaccurate data.There is a delay in the slope data for climbs and it varies based on ascent bs descent. The speed is accurate or the distance of a ride (avg), but may vary +\- 0.5 mph for the current velocity (compared between android phone, wahoo ELEMNT, and wheel mount magnet with measured circ.Overall a good value for money that offers decent accuracy with some tolerance for error. Issues with pairing are primarily due to lack of any+ on the iOS and the dual ble signal of the units.

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!

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.

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.

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.

Sensors do not automatically pair with the Coospo CS300. First, The lights do not work except for one brief second--How can you see these on the front when you are changing the batteries on the back to switch from speed to cadence? Tried multiple times to pair them. Even replaced batteries. No Luck. Will return and buy other sensors--Interesting that these are not sold in the bundle! I thought that buying from the same company would make things easier!.

Simple to install and use. Fantastic addition to indoor training (I use the cyclometer app with two of these. One for cadence and one for speed.
