It's true! It magically kills batteries!

By PorQueNo

Pros

  • Helmet/Removable mount

Cons

  • Short battery life

Best Uses

  • Front headlight
  • Rear safety light

Comments about Knog Frog Strobe Front Bike Light:

I thought it was the rain I have to ride through that was killing the batteries every two weeks. I feel strangely vindicated that everyone else agrees with me ... this cleverly designed, really appealing, terrific "I'm here, don't door me" flasher just magically kills batteries. All by itself. If Knog can fix this then they'll have a heckuva product, because it's GREAT other than the battery issue. You can pop it on a helmet - handlebar - to a backpack strap if you like. OBVIOUSLY, it's not going to illuminate pitch darkness by itself (note the size of the thing!) but that's not its job. We all probably know the pain of affixing the proprietary bracket to your handlebars only to lose the light - or never getting the bracket to stay in one place. No problem with this. But, again, wait for the next version, 'cause this particular one is just too maddening.

Comments about Knog Frog Strobe Front Bike Light:

These lights are handy and easy to install and use. I have some older ones on one of my commuter bikes, and they have lasted several years and are still going strong, even though I've never changed the batteries in them.

However, these Frogs are terrible. Somehow they drain the batteries even when off. I've confirmed this with different lights and several times when I was positive that I didn't leave the light on. But if I don't use the light for several weeks, I will find that the batteries are dead. Replacing the batteries is getting expensive, so I'm getting rid of these and will try something else. Truly disappointing.

    Comments about Knog Frog Strobe Front Bike Light:

    Had it for 6 months, 5 of those it was in the box. This fall due to the short daylight, I put it on my road bike handle bars not a a headlight just a headsup for oncoming traffic.

    Switched it from one bike to another, 3 times and then did not ride for approx 2 weeks, left it on the bars and found the light on the ground the other day. The strap broke.......

      Comments about Knog Frog Strobe Front Bike Light:

      I recently decided to pick this up for a couple reasons. First, my morning commute is now in the dark (6am) and second, this puppy is on sale. I've been riding with just a tail light but with the dark mornings I wanted something so I will "stand out".

      I would not classify this as a "head light". The reviews who mention this having a weak beam are right...this isn't to see in the dark, it's to be seen. There are four flash modes, ample enough to get the attention of anyone on the road. The size is great too...can hardly tell its there. The battery life hasn't been an issue either.

      Knog makes stellar products and that's exactly what this is.

      If you need a reliable head light to see the trail spend the $$$ and get a NiteRider.

      I bought this for visibility during my commute. I like the form factor. The battery life is VERY short; the battery died w/in 3 months w/ about 30 min of total use.

        This light is wimpy even when the batteries are good. The ones supplied run down fast and to replace the two watch-style batteries costs more than $10. Don't waste your money.

        • Safety Light

        Comments about Knog Frog Strobe Front Bike Light:

        I had such high hopes for this. I like how I could easily interchange it from bike to bike and even take it with me on runs. The battery life is the killer. It takes 2 lithium batteries that will run you about $10 for both. I think the thing turns itself on or drains the batteries while turned off, because I need to buy new batteries every few weeks, even when I don't use it. Well, I bought new batteries twice, then I replaced it. If they can figure out a way to ensure battery life, this thing will be great. Perhaps a toggle to engage the battery and the button to turn it on would help prevent accidental turn on or random battery drain. I hope they get back to the drawing board and do some troubleshooting, because the potential is there.

              This light seemed to drain off the batteries even when shut off. Since the CR2032 batteries are about $5 a piece that was pretty lousy trial and error discovery. I'm going to get something different. On the 2 or 3 occasions when it was not dead, it was about as bright as I expected for being so small.

              Comments about Knog Frog Strobe Front Bike Light:

              This light is good as a front or rear safety light on overcast / gray days. But, not bright enough for night riding. The claimed battery life of 80 hrs is over stated. My experience is 20-30 hrs on flash mode. I noticed that my light changes modes by it self if riding on rough roads. The rubber strap broke on my light after one month of use.

              I bought both the front and rear versions and both are really nice . They definitely let runners and other cyclist know your there at night. Although I am happy with them I would not recommend it as a primary source to light up the street or a dark trail .
