Knog light bliss - a Boomer Rechargeable and Wearable review

Knog, the Australian-based bicycle product company, sent me over some of their new bike lights to test out -- and they did not disappoint! Since it's (already) that time of year when the sun starts setting before I leave the office, I've been able to use them this entire month... 
The Knog Boomer Rechargeable comes as both a front white light and a rear red light - and doesn't require a single battery, hence the name 'Rechargeable'. I just plugged it directly into a USB port -- more on that below. The lighting quality is superbly bright and was particularly impressed with the front light which reflected every street sign half way down the block on my commute home through Brooklyn  ('up to 55 Lumens' as noted on their website). They also have 4 modes of lighting from HYPER blinking to solid. Although twice the price of their popular Frog Stobes you get more then twice the power ♥ hence more visibility ♥ and don't have to buy another bike light battery.

The Boomer comes in a silicone body which fits varying handle bars/seat tubes sizes and doesn't require permanent hardware -- once locked up I could easily grab them off my bike in seconds. The front light easily attached but I was a bit apprehensive with the way the rear light has a smaller fastener you have to make sure slides in - yet it never slipped off or loosened.

So, more about the recharging process... these lights are smart little things. They have a built in warning system to let you when you are soon in need of a recharge and the USB plug is built into the light itself so you just have to slip off the silicon casing and plug it in vertically (I used my MAC desktop). I did notice that once plugged in, I had to push it side to side to make sure it maintained contact and make sure it was recharging. The rear light was easy to remove from the casing which peeled out like a banana while the front light took a little work to remove -- the best way was to push on the bottom to slide it up.

It just so happens that last year I bought another brand's rechargeable light but ended up pretty unhappy for two reasons: 1) in order to recharge it you needed to use a separate USB plug attachment that came with it but was so tiny I misplaced it for weeks; and 2) the bike attachment's Velcro strap, which I thought was nice and minimal, broke in half. I mention this since Knog's design doesn't have either of these issues. For weeks they've been reliable and easy to use + come in six colours so you can accessorize - and who doesn't like to have that option?! Silicone is a sticky material though I had no problem cleaning off grease (along with remnants from the bottom of my bag) by wiping them off with soap and water - after all, they're waterproof! 
Also tested out their Boomer Wearable with an integrated clip ALONG with a removable magnetic plate which attaches to your clothing/bag (similar to my Flower Power reflectors) -- pretty freakin awesome! The magnetic strength was strong I was able to wear it on my canvas bag and would work great on a jacket. I actually ended up using the clip on my belt (mostly out of habit) but still found it to be one versatile light.


  1. This light is very important specially in dark roads while biking, so if don't want to be hit by a car, then make sure that you have lights with you.

  2. I'm getting all of these - Knog boomer rechargables and the wearable.
    I'm also thinking headlamps - 1 front and 1 back for this winter. I realize I was riding so much in the dark last year. Scary!

  3. Hey, Julie... you know they come in ♥PINK♥

    I do think a lot of people under estimate the need to use lights in the city... as well as using them when its dusk and not totally night and any type of rainy situation. Since I'm also occasionally behind the wheel I know first hand how hard it is to see a cyclist -- even on quite streets in Brooklyn.

  4. Big thanks for the review - I bought the boomer rechargable on your recommendation and I love it. Reflective signs as far as 2 blocks in front of me flash when it's super-bright light is on and I think cars take my presence more seriously.

  5. ctwigg,

    I also adore my front Boomer - it's the best front light I've ever found and so easy to take on and off.

    Someone did point out that the rear Boomer Rechargeable didn't fit on their seat post. It's true that you need at least 2.5"of clearance to attach it below your seat -- though most people have that).

  6. Thanks for the review Vanessa, I've been reading about these for a while and have just ordered a rear light with a front one to follow later! Good thing I've just raised my seat post or I wouldn't be able to squeeze the bad boy in!
