It comes packaged with a pre-installed battery, rubber mount, zip ties, shoe mount, 3M double-sided tape, a quick start guide, and a product info guide.

Couldn’t be any easier to use

I've used it several times

Works perfectly and extremely user friendly. Highly recommended!

Works great... until the battery dies.

I've put it through the wringer

At which point you have to open it. Now wahoo could've included a $0.10 tool and saved me the trouble of destroying mine trying to open it but no. So mine is now garbage BUT it has a new battery! Woohoo! Seal is completely toast and plastic won't even snap close. Done with this company and their cheap crap.

Unintended Consequences

I've put it through the wringer

It mostly works. But beware, this has been known to cause issues with other Bluetooth sensors in a Zwift environment (ie you're pairing your smart trainer with Zwift via Bluetooth instead of ANT+). It's also caused me to have issues with other Bluetooth sensors (HRM strap) in a non-Zwift environment with an Elemnt Bolt. Bottom line - it might, or even probably, will work for you but there is also a good chance it will cause issues with your Bluetooth sensors. Beware.


Will this work with iPhone X and MapMyRun or mapmyride?

Simple and affordable

I've used it once or twice and have initial impressions

nothing to complaint, really easy to setup with Wahoo Elemnt Bolt

Easy Peasy

Super easy install with some squishy double sided tape (which is included). Just take it out of the box, put it on your crank arm and you have cadence!

The Solution

I've put it through the wringer
True to size

So the huge perk to this sensor is that it will send a Bluetooth signal and an ANT+ signal. If you are planning to ride your Kickr / Kickr Snap synched to your tablet or PC and don't want to buy an additional ANT+ sensor, but you want to see cadence. Then this is what you need. If you arrive at the group ride and unload your bike only to realize that you left your head unit at home, but you still want accurate data to track, just sync your phone and you are good to go. I also have the Tickr Heart Rate monitor which will also communicate with my computer for indoor Zwift rides, my Garmin for outdoor rides, and my phone, for when my Garmin isn't where it should be.

Easy to set up and works great!

I've used it several times

I use this connected to my cleat and it has worked great over my first few rides. For the second ride it didn't connect correctly, and had to forget it and reconnect. All fine since then. It seemed like it could have been the app/phone's issue as the included Wahoo app was able to recognize it. Using with Iphone 6S and mapmyride
