Frog - Quick Start Guide (EN)

Customers praised these bike lights as "bright" and highly visible with multiple light modes. Shoppers loved the compact, lightweight design that fits in pockets and easily mounts on bikes. USB-C charging and long battery life were appreciated. One customer noted the rear light mounts sideways, reducing light spread effectiveness.

  • Easy to use, easy to charge, bright and fun to watch
  • Fits in your pockets and is always easily mounted on your current bike
  • Such a tiny, unexpected sleeper powerhouse!

Shipped from Amazon

Buyer beware, these lights ship from Amazon. Thought I was supporting a small, independent business. Instead I gave my money to the devil. What a bummer.

A classic gets even better

After a multi year break from cycling, I’ve just got back into it and if course had to buy mostly new gear, including lights. After much research I settled on the Frogs for a number of reasons (USB-C charging high on the list).
While waiting for the lights to arrive, I came across my old lights, only to discover that my previous rear light was actually the original version of the Knog Frog! Great to see them going strong, and still making quality gear.

Great lights!

These are super convenient, easy to use, and provide decent light for kicking around town. Not sure I'd use them for trail riding or touring, but they would make a nice auxiliary light for visibility if you already have a high powered set.

Good for the cost!

Not super bright but as advertised, good enough for city biking and at a fair price

Love it

I was looking for a compact front safety light with a long run time. Love the Knog frog as it is a nice design, has lots of run modes, and holds a charge for a long time. The only ask would be to keep improving battery life and keep the price competitive! Would happily buy another.

KNOG Frog

Love these sleek Knog Frog front & rear lights. Their charge lasts a long time, they put out plenty of light, and all the different blink options are just cool. I have 3 sets for 3 different bikes. Only issue I’ve encountered- found one lying on the garage floor a few days ago. Looks like the rubber became compromised somehow and came apart.
Not sure what happened, so may need to order a new front replacement Frog light.

a bit small

The lights are easy to slip in your pocket and easy to put on/remove. They are the same size, and while the rear is adequate, the front does not give out enough light to light up any sort of path. I will need a different light for dark paths and streets.

Great be-seen lights!

I ordered these as a set (slightly on sale?). Remembered the old Frogs fondly and the new ones are way better. Not super duper bright but I commute around a well-lit city at night and use them as attention getters. Interesting mode choices depending on the application. Good battery life I feel, though charging takes an hour or two.

Quality update

A nice improvement on the old frogs and other small Kong lights. A great set to have on the bike to be seen in low light when your ride went longer than planned

Superflexible, easy rechargeable, highly visible lights

The bike lights for everywhere. in case you find yourself changing between different bicycles you will find situations where you have always to make sure you have enough light on your bikes. Knog Frog fits in you pockets and is always easily mounted on your current bike.

Bright like a diamond

Easy to use, easy to charge, bright and fun to watch…I really like the various light modes and the charging indication when you turn it off!
Right know I’m ordering more for my whole family! Even those without bikes…

Fabulous Frogs

My eBike has lights but I wanted some flashers to make sure I was noticed. These things are brilliant. So easy to use, charge, and install.

Knog frog

They work great👍

I have the originals, and these are smaller, brighter, have more modes, more battery, and a wider spread of light. They maintain the originals' ease of use and flexible mounting, and are even more unobtrusive. The only negative so far is the way the rear light mounts sideways, which negates the benefits of the wide spread of light.

Small and mighty

I just love how easy those tiny lights are. Easy to fit on any part of your bike, they just make sure you get noticed when it's dark. I took them on a ride and ran out of daylight - it was just reassuring to know other road users could still see me. I especially love the fact they also shine to the sides, and the knight rider mode.

Excellent mini backup lights

I'm always forgetting my lights so keeping these attached to my bike or in my bag does not take up space and they aren't something that are much of a target for thieves. The new updated design and modes and runtime are so appreciated. Such a tiny, unexpected sleeper powerhouse!

Small but Mighty!

Fantastic lights. Love the ease of attachment and removal and their small footprint. I had the previous battery-powered versions, and they were great, but these are brighter, feel sturdier, and the fact that they’re rechargeable is a true deal-sealer. 10/10, would buy again. Can’t recommend ‘em enough.

Awesome light!

We use these lights for our boys’ bikes and they are great for illuminating their way. We have a pretty mellow street for cars but the boys can be seen from afar with these lights so we have a better peace of mind when they use them.
