Lezyne Zecto Drive² Ai Alert Rear Light

The Lezyne Zecto Drive² Ai Alert rear light is a compact LED bike light, rechargeable via USB-C and designed for everyday use. The Ai Alert braking sensor, trained using artificial intelligence, recognises when you slow down and alerts other users to your presence. It has a Day Flash mode for high daytime visibility and Wide Angle optics with coverage up to 270°.

It attaches with a quarter-turn mount, suitable for round, D-shaped and aero seatposts and compatible with most systems of this type. The 650 mAh battery is user-replaceable and the IPX7 rating protects it against water. The light weighs 39.6 g and the USB-C cable is not included. It is not StVZO-approved, so it is not suitable for road use in Germany.

Founded in 2007 in San Luis Obispo, California, by Micki Kozuschek, Lezyne is now based in Reno, Nevada. It makes pumps, lights, multi-tools and bags to accompany cyclists on their rides. In 2011, it began developing its own LED lights.
