CooSpo ANT+ Bluetooth Technology Wireless Waterproof Fitness Tracker Speed or Cadence Sensor ¡Â­

UPDATE: I've been using these sensors for several months now and just raced the SERC #3 race in Bryson City 1-14-2019. Weather was a mess and the tracks was all mud as it poured rain on us through the entire event. The sensors worked flawlessly and took the punishment of the mud and grime, including being completely submerged.I ride XC and some Enduro, putting about 3000 miles a year on my equipment. I was attracted to these because they were self contained FOB style at a very nice price point. Therefore, I purchased 2 of these sensors, one for cadence and the other for wheel speed. Currently I run them connected to a Lezyne cycling computer. However, for purposes of this review, I took the time to connect directly to an iPhone 6 and verified connectivity with both Wahoo and Strava (see attached pictures).The product comes in a sturdy, retail box with nice packaging. It includes the sensor, 2 large bands, 2 smaller bands and 2 mounting pads. Instructions are also included and have an English version that is easy to understand. The included bands are thicker in diameter than some of the others I have seen with Garmin and other devices, which is nice as I believe they will hold up better. I would estimate the thickness to be about 3.5 ml vs the 1.5~2 ml ones from other manufacturers. There are 2 rubber mounting pads, each are a different style. One is flat and the other concave. The flat one is used for mounting on a crank arm, the curved for your wheel hub. Installation is a snap, however, if you have a small J hook or similar dentistry tool, it will make installing the retaining bands a little easier. Remember, tight is good as you don't want them to move once installed. The mounting hooks on the sensor have a split in the middle, and it's the correct width for a small zip-tie. Although the bands look like they will do the job, I've added the extra security of a zip-tie. Being a mountain biker, I have been known to knock magnet sensors off my cranks that were secured by only bands.Setup: This is pretty straight forward. You will need to open the battery door with a coin or key and remove a plastic film which keeps the battery from making contact. When you reinstall the battery, you will want to do it with the top of the sensor facing you to see the light, as it doesn't stay on for very long. The color of the light is how you determine what mode it is in (speed or cadence). To toggle modes, simply remove and reinstall the battery. No buttons or complicated setup required, that's it.Pairing:First I paired to my Lezyne computer, which recognized them immediately. Once I had them connected, both icons were visible on the main screen. (see attached images). Also, in my images you will see 2 shots of the computer, one showing a speed reading, and the other a cadence reading. I tumbled each separately in my hand to confirm transmission.Next, I opened Strava on my iPhone 6 and paired from the Strava sensors page. Cadence mode will connect either individually under 'Cadence' or as cadence under 'Speed & Cadence' (see screen shots). However, speed mode will not connect. NOTE :: THIS IS A STRAVA ISSUE. You can go to the support threads on Strava's website and see plenty of discussions on the speed sensor issue. I do not know why Strava will not fix this issue, but using the Strava iPhone app with a speed sensor doesn't work. I posted a workaround for this on the support thread, but the long of the short is to use WaHoo or other app for recording and then share it to your Strava account. It's inconvenient, as you have 1 extra step, but it works.For Wahoo app on the iPhone, setup was a snap. A really nice thing about wahoo, is it will display the broadcast serial number for the sensor which is also printed on the back of each sensor. In the event you pull them off your bike for cleaning and mix them up, Wahoo will help you identify which is which (see screen shots).Durability:I have not had these sensors long, but they do appear to be well built and the battery door has a nice water and dust proof seal. I will only update this post if there are issues with durability.My Thoughts:If you are looking for a good set of sensors that are small, self contained and do not require magnets, at are really good price point, I would highly recommend trying a pair of these, it really seems an obvious purchase choice.My thoughts on CooSpo - I originally came across this company 3 years ago on aliexpress. I have purchased several of ther HRM chest straps and 2 Cadence/Speed combination units. I've never had any issues and I've only replaced units that I lost, or I damaged from severe off road riding. Their previous products have lived up beyond my expectations and I have high hopes for these newer models.

Bought this to save some money, didn’t want to buy the Garmin or Wahoo $60 choice1. Instruction is not that great. It took me a while to realize the LED indicator is very brief(~1second) to show it if is in cadence or speed mode.2. BLE doesn’t work on Garmin Forerunner 945. It will just always be searching and searching.3. ANT+ mode worked well4. Only used it In cadence mode, accuracy seems to be fine. Probably will switch to speed mode because I have another cadence monitor5. Installing in speed mode was a little tough, but I had an small L hex key to use it as a hook, it worked ok.Overall, great value for the price, maybe compatibility is meh, but I didn’t care, since it works on ANT+

It was easy to use and install, and paired right away. I used it for the speed mode with the IpBike app on my android phone. Looks like it very accurately tracked distance. A little tricky to make sure you get the right mode, as the indicator light is on the opposite side of the battery. Not a huge problem though.I got nowhere near 500 hours of battery life with it though. It doesn't indicate that the battery is low other than by dropping rotations. You'll notice the displayed speed suddenly halving or dropping to a third of your actual speed, and distance tracking doing the same. I think it was closer to 50 hours of riding before I needed to change batteries. I probably went through half a dozen this summer. I store my bike in my apartment and I think it's possible my phone is keeping the sensor on even when I'm not riding or using a tracking app, but that's just a guess. It would not be worth unplugging the battery from the thing after every ride to test.After about 600 miles this summer, it stopped reliably working completely. Every ride it would either refuse to start up, or completely die in the middle of the ride even if I had just changed the batteries. For the price, I guess I can't really complain much. I'll either splurge on a more expensive sensor, or just resort to GPS tracking next year.

After purchasing a CooSpo BC200 GPS Wireless Bicycle Computer I seen this as an add-on. These sensor can do either Cadence or Speed, and can even run two separate sensors. Figured since the GPS already accurately records everything just fine, would go for Cadence, which helps a person cycle better and give them a set pedaling speed for optimum performance.If you have a CooSpo BC200, or other GPS Cycling Computers, this is a very effective & accurate sensor that won't break and back. This sensor also *does not* require magnets to operate. Simply attack to the inside of a crank arm, with a supplied thick rubber band, and swap the battery to its correct LED output (think was blue). Pair it up with the BC200 and spin the crank and see the Cadence kick in within a few seconds.Am glad to have gotten the Cadence Sensor. For the price am tempted to get another for the Speed, but would rather opt for a CooSpo Armband Blood Pressure Monitor. Wished I could get an Amazon discount on one.Inexpensive, Effective, Simple.

The Peloton app on Ipad mini 2 recognized this sensor without issue. The sensor attached easily to the crank on my Sunny Fitness SF-B1805. Working fine through 100 spin classes over the past year.. I will update as time goes by.
