About this product
Illuminate Your Ride, Safety All Night! Night cycling shouldn't be a nerve-racking adventure. We make safety as simple as breathing. At only 0.99 oz (28 g), this taillight features a 150° wide-angle beam that can be seen from 328 ft (100 m) away. It delivers a true 15-hour battery runtime to keep you visible from dusk till late-night rides. Whether you’re doing suburban night training, climbing mountain slopes, or commuting through rainy evenings: just mount it to your seat post or saddle rail, and it activates automatically as you pedal. Heavy rain, rough gravel roads, long-distance trips — it keeps flashing steadily, protecting your rear visibility the whole way.
