Adventure Labs Magene S3+ Sensor

The Adventure Labs Magene S3+ is a wireless speed and cadence sensor built for cyclists who track indoor or outdoor rides. It connects via Bluetooth and ANT+ to popular training apps such as Zwift, Wahoo Fitness and Onelap. A single unit operates in one mode at a time, so two sensors are needed to capture both metrics simultaneously.

IP66 Rating and Battery Operation

The sensor carries an IP66 rating for dust and water resistance during wet rides or sweaty indoor sessions. It runs on a pre-installed lithium manganese dioxide battery that is activated by removing an insulating sheet. Re-installing the battery toggles between speed and cadence modes. The unit enters a sleep state after one minute of inactivity to conserve power.

Upgrade From Basic Magnet Sensors

Riders moving up from simple magnet-only pickups gain wireless connectivity and multi-app support without adding cables. The jump is worth it when you want simultaneous ANT+ links to a head unit and a phone app, or when you need IP66 durability for year-round training. It does not suit buyers who want a single device to record speed and cadence together.

Questions about this item

How do I install the Magene S3+ on my bike stem and which step is often missed?

Mount the sensor on the stem or handlebar using the supplied mount, then pull the insulating sheet from the pre-installed battery before pairing; the sheet removal is the step most riders forget.

What maintenance will the Magene S3+ need later?

Replace the lithium-manganese-dioxide battery when the unit no longer wakes from sleep; the cover opens without tools for a quick swap.

What limit appears first during a long indoor session with the Magene S3+?

After one minute of no movement the sensor enters hibernation and stops broadcasting until it detects motion again.
