Customer Reviews
very good small compact light perfect for MTB with dropper posts.
The Frog Rear Bike Light is quite versatile offering several lighting modes. I found it to be the best option for my bike as it could install in different spots since its flexibility allows it to wrap around different size points. In my opinion, the full single charge also provides a long battery life.
Easy to use. Lots of modes . Seems pretty bright.
easy to use & bright light to ensure you are seen.
