Frog - Quick Start Guide (EN)

Customers praised this rear bike light as "brilliant" and "compact and bright," perfect for mountain bikes with dropper posts. The light offers nine functions, easy USB recharging, and excellent visibility. However, one customer mistakenly ordered rear instead of front. Minor drawback: must detach to charge.

  • Brilliant piece of kit. And a local brand too!
  • very good small compact light perfect for MTB with dropper posts.
  • light, tiny, versatile (I attached it to my helmet) and bright!

Love this little guy

This light is super simple to use and very versatile. I can connect it to my seat post or if I'm using a rack with gear on it I can mount it to the my bag strap. It's surprisingly bright for such a tiny light. I am definitely satisfied with my purchase. I may even get another rear light to go along with it just for style points. Cheers Knog 🍻.

The Versatile Frog

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.

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.

Does everything that I excepted it to do. I always forget my bike lights so this is a perfect backup to keep in my frame bag.

Great light, mounting not suitable as a tail light.

Light works great but must be mounted on right or left side of seat post, both of which interfere with pedaling motion on most riders.

Great Battery Life And A Smart On/Off Button

1. Great battery life. It Lasts several hours, maybe a days worth of hours before it needs to be charged again.

2. You don't have to go through all of the modes every time you turn it on and off. Just long press to turn it off, and the next time you turn it on, it I'll be on the mode it was on when you turned it off.

I love the Frog Rear Bike Light!

I love this light. I have 3 of them now. I love that they are rechargeable - super easy to charge, super easy to put on/take of the bike, and I love the different unique lighting movement settings. And I can easily use multiple of them for even greater visibility. Keep the great lights coming, Knog!

Rear Lights

I bought 2 rear lights for my mountain bike. The lights have been perfect! They recharge easily and hold their charge well while riding.

Bright spark!

What a great product - light, tiny, versatile (I attached it to my helmet) and bright! The nine light functions are cool. My only (minor) beef is that I have to detach it to charge - but I guess it ensures the unit stays water proof. I thoroughly recommend this product. Andy, Wollongong

Happy Customer

I bought this light for when I have to ride pavement to access trails. It’s great! It would be perfect if the strap thingy was a few millimeters longer. It’s a tight fit around my OneUp dropper post, but not a significant concern. I definitely recommend this light.

Works Great

I bought two of these to use on my kids' bikes. Previously we'd used some bargain lights bought from a big online retailer but they were clunky and not always reliable. Super happy with the form factor and brightness of these rear lights.
