Customer Reviews
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.
Ultra-Bright light! No way you cannot see me!
I forgot one thing. You have to feel around for the button on the circuit board. It might've helped if they put a button on the rubber where the button on the circuit board is. The button on the circuit board is so small that you have to prees the rubber in the exact right spot or you'll miss it.
I don't know if it's because of this or because I use the light a lot, but there's a divot in the rubber where the button is. There's also a half inch diameter ring in the rubber around the divot. I don't know if that was there when I got the light. Maybe that ring is their lazy way of indicating where the button is. But I still love the light.
