North Pole Engineering Runn Smart Treadmill Sensor - Retrofit Smart Treadmill Sensor, Bluetooth & ANT+, Black

Works with my 20 year old treadmill to feed speed and incline numbers to the peloton app. Speed seems accurate within 0.1 mph. For incline I finally realized that both my treadmill and the peloton app report incline as percent (grade), not degree. Now the accuracy is within 0.5 units. As others say, the stickers fall off very quickly. I got a white sharpie and drew the lines in. Works great.

Works very well. I use it paired to my Garmin watch and it’s accurate and reliable. One star knocked off because the battery can suddenly drain very fast. I leave it continually in charge now.

Easy to set up and worked immediately. Takes a few minutes to calibrate the speed of the treadmill with the Zwift run application. I found it gets around 90% accuracy. The problem with it is that it occasionally turns itself off in the middle of a run. You know it has happen because your Zwift Atavar will stand still while you are still running. Its a bit annoying having to slow the treadmill, jump off, turn the sensor on again, jump back on and get back up to speed. When its bad it may happen every 2Ks. Given I am old and only run 5Ks I try to think of it as a stop to have a drink.😅

Great product and very quick and easy to set up. Trouble free running on the treadmill with Zwift. A lot more accurate than a foot pod and trouble free fast connection. Long battery life with easy recharge.

I purchased this Runn treadmill sensor to use with my non smart Mobvoi treadmill. I subscribe to the Peloton+ app and wanted a way to accurately record my runs and workouts. Peloton now support FTMS Bluetooth sensors - this is one of those such sensors. The sensor is relatively small and fairly easy to attach and configure to a standard treadmill. Everything you need is in the box, including a sheet of reflective stickers which you must attach to the treadmill belt at intervals of around 18". In all, set up took me around 15 mins to complete. You then need to download an app to configure the device as out of the box it was widely incorrect especially when reporting the incline. My treadmill does not support incline so i set this to 0 in the setup app. There does not appear to be a way to disable this function, i am hoping that in a future update of the app you will be able to switch this off. Connecting the device to the Peloton app was simple and straight forward, you do this within the actual Peloton app. On my Android phone the Runn reported the correct statistics such as speed and pace directly into the screen overlay of the running workout. I was impressed! My partner however uses an iPhone and this is where our problems started. The stats from the Runn device only display on the IOS app if the device is in portrait mode, landscape mode results in all of the stats disappearing. After much research it appears that this is a fault with the actual Peloton app rather than the run device. Apparently Peloton released an app update for IOS in Feb to correct this, but it is still not working! This is super frustrating as using the device in portrait mode results in a tiny video playing. Hopefully Peloton will eventually release a fix for this issue. Now for the device itself, one problem i did experience with this device is that due to the fact the sensor has to stick out slightly over the running belt, both my partner and I found ourself kicking off the sensor on occasions - i suspect this is due to our treadmill being a narrow home treadmill. The 3M tape that holds the sensor bracket to the treadmill is not strong enough to keep it attached permanently. If you have a wider treadmill then this may not be a problem for you. Luckily despite us kicking off the sensor several times whilst running it does seem robust and has not yet broke! The reflective marking stickers have remained on the belt without issues, i note other reviewers have stated the come off, however i have not experienced this issue myself. In summary this is a great little device that makes a dum treadmill smart. If you have an android device and use the Peloton app then i would recommend this - however if you are using an iPhone/iPad then you may want to hang on until Peloton update their app to enable the FTMS function to work correctly.
