This rear bike light charges in 1.5 hours via USB thanks to its 300mAh lithium-polymer battery, providing up to 12 hours of continuous use or 30 hours in flashing mode. A built-in LED alerts you when the charge drops below 20%. Perfect for long MTB rides or city riding.

Detects braking within 0.2 seconds and instantly activates maximum light – visible from 150m away. With 4 modes (steady/flashing/strobe/pulse), it's one of the smartest rear lights for road and mountain bikes.

It automatically turns on when the light fades or the bike vibrates. It turns off after 30 seconds of inactivity to conserve energy. Perfect for those forgetful people walking home after dark.

The machined aluminum alloy housing is drop-resistant up to 2 meters. The surface is scratch-resistant and weather-resistant (do not immerse in water). It will withstand even the most challenging mountain bike trails and high-pressure washes.

Two tool-free mounting options: on the seat post or under the saddle. Compatible with 95% of bikes (road/MTB/folding). 2-year manufacturer's warranty—no questions asked replacement for defective products.
