The Lezyne Radar Drive is a rear bicycle light with built-in radar that detects vehicles approaching from behind at up to 150 metres. When it picks one up, the light automatically switches to a distinct alert flash aimed at the driver. It also runs as a standalone tail light, with a 300 lumen daytime flash among its seven output modes.
Rider alerts travel over Bluetooth and ANT+. Paired with Lezyne's React Drive front light the system gives audible and visual warnings without a phone, and it also reports to the Lezyne Radar Ally app or an ANT+ compatible bike computer. The co-moulded body is IPX7 waterproof, charges over USB-C, runs up to 20 hours, and straps to round, aero and D-shaped seatposts.
