Lezyne Saddle AI Alert

The light uses an internal accelerometer combined with machine learning to detect when you are slowing down. When it senses deceleration, it automatically boosts the light intensity to signal drivers behind you, without needing any complex setup or external sensors.

The Lezyne Saddle AI Alert is specifically designed as a saddle mount. It is compatible with most standard saddle rails, but you should ensure your seat post setup allows enough clearance for the mount to attach securely beneath the saddle.

Yes, it carries an IPX7 waterproof rating. This means it is fully protected against immersion in water up to one meter deep for 30 minutes, so it will easily handle heavy downpours and road spray during your commute.

The light features wide-angle optics that provide 270 degrees of visibility. This design is specifically intended to help you be seen by traffic approaching from the sides, not just directly behind you.

No. The machine learning algorithm processes braking events locally on the device to trigger the light's intensity. It does not track, store, or transmit any personal rider data.

With an 1100 mAh capacity, the light is built for daily use. While exact runtime varies depending on the output mode you select, the USB-C fast charging makes it easy to top off the battery quickly between rides.
