COOSPO Cadence and Speed Sensor, 2 in 1 Bluetooth ANT+ RPM Cycling Cadence Sensor, Wireless Bike Speed Sensor for Bicycle, Compatible Cycling Computer/Rouvy/Peloton/Wahoo APP

I’ve had this for almost a year now and have one installed on both my hybrid and road bikes. I love it! It has stayed secure for many rides(bumps included) and nothing has fallen off. Setup was easy and I was easily able to pair it with my Cycplus bike computer, which was the brand of my previous and first sensor set(it all came in a bundled kit). The Cycplus sensors were a disaster as they only attached by bands which broke after one or two uses and even rubber and silicone bands didn’t work. They fell off all of the time and I was always wasting precious riding time having to find where the stupid thing fell off and then get a fresh band and reattach it. It was a huge hassle and that’s what prompted me to look for something else and I came across this COOSPO sensor. I wish I had got COOSPO to begin with. It seems pretty accurate as far as I can tell, as it closely matches what my smart watch says. Being this is only the second sensor set I’ve ever used, I can’t draw any comparisons with more expensive sensors or more high-tech models, but the price cannot be beat for this and it works for it’s intended purpose plain and simple.

I feel like this speed sensor deserves some kudos simply because it is very difficult to find a cyclometer for your bike that can be installed on the rear wheel and that works well. I have a 26" mountain bike that I typically take for a spin thru the year or use for exercising, however during very hot days or even raining or cold days I like to mount my bike on a stationary/ training tool and pedal in place and want to track my speed and pedaled miles. Every speedometer I looked into works well if is on the front wheel because that is the one that typically moves, or most of the new ones now come with GPS tracking which does not work if I'm using the bike in place. Long story short, this speed sensor works and functions well. It comes with 3 pieces, 1 piece goes on the back frame of your wheel, the other piece on the spoke, and one piece goes on the pedal area. The sensor connects easy via bluetooth to the app suggested on the site or the manual (I use the wahoo app and works great). The manual could use small improvements as it is a bit hard to follow. For me the hardest part was to install it correctly, it does take a bit of practice and trial and error a few times. Once you got where it needs to go, you use the zip ties they provide. They also provided a small allen wrench, which I have no clue where it goes as it is not needed. The piece that goes on the frame (the sensor), has a small arm which you can bend back and forth to make it closer to the magnet on the spoke to establish connection. It is easy to know if the pedal piece and the magnet are in range or lined up because the sensor has 2 small lights, a blue and green and as you move the wheel to test, you see the blue light go on, and the pedal when used and the magnet from it gets in range of the sensor, the sensor's green light goes off. Every sensor I have seen requires the sensor and magnet to be within 2-5 millimeters apart, well no issue with this sensor you just bend the small sensor arm as much as needed to be in range. far as battery life, too soon to know as I just got this and have been using for a few weeks, but uses a CR 2032 on the sensor. I would buy this over and over again because it has a very good price compared to all the other cyclometers that can range anywhere from 30-100's of dollars with wireless sensors, and GPS tracking, that mostly work on front wheel only, where this is small, simple and works with stationary bikes and super cheep.

UPDATE: Yes it failed, yes I really still gave it four stars (originally 2) First I view small parts such as this more as a consumable. While mine failed out of the box after writing this COOSPO customer service reached out to me and offered a full refund, without me asking. Anyone who provides good customer service deserves to be reconized. I have other small sensors from COOSPO all of which work well. The quality seems hit or miss. Mine was miss. I really wanted to like this item as I found it well made for the price. But, the battery drained within a day as did the replacement battery. The range from the sensor to the computer also seemed to be extremely short, no more than a meter. Ended up simply replacing this with two https://www.amazon.com/dp/B08252X8VS.

Worked out of the box! Easy mountain, just followed the instructions and everything fit and was easy to set up and use. Has great accuracy so far, looks like it's very well made so it should be adorable product as well. Set up was particularly easy just follow those instructions and you shouldn't have any problem with it. I love this product. I absolutely love the feel of it. I love the functionality of it, the functionality, it was easy to mount and and feels like a durable products as well as having a great price.

This product does not work. The cadence sensor worked but the speed sensor did not even when the magnet was super close to the receiver. I returned the product.

Cadence kept dropping out after about 10 min. I would have to pull the battery to reset it. The pick-up was as close to the wheel magnet as possible without touching. Battery showed 100% but I tried another just in case. Did not fix. Speed would work but if it went to sleep, I would have to unpair and repair through the app- so basically every time I took the bike out after leaving it overnight. My fault - I kept adjusting the speed sensor. The cadence sensor is on the pedal.

This might work on certain bikes but I tried it on two and couldn't make it work. The cadence magnet has to be extremely close to the sensor. They say 1.2 mm but I couldn't make it work even that close. None if my bikes have a distance from crank arm to chain stay that tight.

The sensors were easy to add to my Trek Checkpoint. My Trek didn't come with Duotrap so I was looking for a sensor package that was inexpensive since I am new to riding outdoors and easy to install without having to take off the pedals and wheels. Just attached the sensor to the crank arm, the magnet to the wheel and the other sensor to the frame. I had to use additional zip ties only because I didn't install the magnets correctly the first time. Overall, very pleased with the purchase and performance. Everytime I get ready for a ride the sensors automatically connect to my Garmin app and bike computer.

Equipamento de fácil instalação e operação, funcionando muito bem até agora

I've been using this cycling speed and cadence sensor for over 100 km, and overall, it’s a solid performer with some room for improvement. Installation & Setup: Installing the sensors was straightforward and took less than 15 minutes, thanks to the tools and zip ties included in the box. I was initially skeptical about the locking mechanism of the speed sensor on the spoke, but it has held up well so far, even on bumpy roads. Pairing the device with my Wahoo Element Roam via ANT+ was effortless, which added to the positive experience during setup. Performance: Once paired, the sensors provided accurate and consistent data, enhancing my cycling experience. The cadence sensor was particularly helpful in fine-tuning my pedaling rhythm. However, I struggled to connect the sensors via Bluetooth, which was disappointing as I wanted to use the device with multiple apps and devices. Build Quality & Design: The sensors are lightweight and unobtrusive, making them ideal for long rides. They also feel durable and seem well-made, though time will tell how they fare under extended use. Pros: Easy installation with all necessary tools included. Reliable ANT+ connectivity with my cycling computer. Secure locking mechanism for the speed sensor. Compact and lightweight design. Cons: Bluetooth connectivity issues remain unresolved. The locking mechanism might need a confidence boost initially. Final Thoughts: This sensor is a great choice for cyclists who primarily use ANT+ connectivity and appreciate a quick, easy setup process. However, if Bluetooth is a must for your setup, you may want to look for alternative options or ensure troubleshooting steps are in place. Rating: 4/5

I bought this speed and cadence sensors. At first both sensors were working fine. But within a week the cadence sensor has stopped working. Tried resetting it but to no avail. Unable to reach the company for fixing now that the return period is over. NOT RECOMMENDED AT ALL.

Worst unreliable sensors . Don’t ever buy anything magnet based .
