Make any treadmill smart for more accurate and optimized training.


No need to buy a brand-new treadmill to start Zwifting. There’s a whole new way to run on Zwift, thanks to the Runn Smart Treadmill Sensor from North Pole Engineering.

The Runn sensor easily installs onto the side rail of most treadmills. Using an optical speed sensor to track belt rotation speed, Runn broadcasts data directly back to Zwift via BLE and ANT+.

What does this mean? You get the most accurate speed, distance, incline, and cadence data while running on Zwift. Helping you level up every time you train.

    Pastilles auto-collantes

    Si quelqu'un à une solution pour moi, je suis preneur.

    Tout comme le message précédent, j'ai un tapis structuré, antidérapant.

    J'ai testé le double face.

    Ce qui fonctionne le mieux, c'est la colle pour chambre à air de vélo. Mais ce n'est pas encore une solution viable à long terme.

    Bien mais pastilles ne collent pas bien

    J ai installé hier et ça a bien fonctionné jusqu au moment où les pastilles se sont enlevées. Mon tapis ayant des petits motifs antidérapant et ce qui gêne la bonne adhérence de ces pastilles. Je vais voir comment faire en sorte de les faire adhérer ( scotch transparent par dessus ?)

    Excellent pour transformer son tapis en tapis connecté.

    Très bon achat pour courir sur zwift. Il permet de mesurer vitesse, cadence et inclinaison du tapis. Un temps de montage restreint quelques minutes pour l'étalonner et c'est parti! Ride On!
