FAQ

How accurate is the S1?
Every unit is dynamically torque-calibrated against a high-precision torque sensor across low, medium and high power ranges, delivering ±1% accuracy. Your individual calibration report is included in the box.

Is cadence accurate on rough roads?
Yes. A six-axis gyroscope responds in milliseconds, keeping cadence stable where accelerometer-based meters get noisy.

How long does the battery last?
Up to 180 hours per charge. A 15-minute USB-C top-up adds about 50 hours; a full charge takes around two hours.

Does it work with my bike computer?
S1 broadcasts over ANT+ and Bluetooth 5.0 and pairs with leading Garmin, Wahoo and Sigma devices and training apps.
