About 12 months ago I thought I’d found my perfect bike light for cycling in London. I was wrong. The Knog Boomer USB is the perfect bike light.
I can tell you exactly why in three words:
Bright, chargeable and convenient
The Knog Boomer stands out as one of the brightest small bike lights I’ve used to date. I’m not the only one who’s noticed. I frequently get comments along the lines of “wow, your bike light is so much brighter than mine”.
With that level of brightness you’d think the battery would be always running out. Indeed, with it being a rechargeable battery you often have to put up with a shorter running time. Not so with the Boomer. I’ve been using it for three months and in that space I can count the number of charges on three fingers.
The third aspect of the Boomer I love is the convenience. It can be fitted and removed in under 5 seconds.
Needless to say I think that me and the Knog Boomer USB have a bright future ahead (Don’t forgive the pun).
So is everything perfect?
Absolutely not. But before I move onto the negatives there are two more things I’d like to mention.
If you are an astute reader of the comments section on London Cyclist you’ll also know that with a couple of Knog lights people have complained of waterproofing issues. I’ve tested three different Knog lights to date and haven’t had an issue with any of them. The Knog Boomer USB is no exception. In the two big downpours I’ve tested it I’ve not had any issues. If any long term issues present themselves I’ll report back on them here.
The second thing I’d like to mention are the four different modes of the Boomer. There’s three different blinking modes and the constant beam setting. From what I’ve seen so far the light doesn’t tend to turn on while it is in your pocket.
Onto the negatives
The Knog Boomer USB sits very near your handlebars. On occasion your brake or gear cables can get in the way. That means you lose out on some of the light that should be shining on the road. The difference is minimal, but it is worth noting.
My second complaint is how difficult it is to remove the Boomer from its silicone casing when you need to charge it. My guess is that it is designed that way to avoid water getting in.
In my three months with the Knog Boomer USB those are my only two complaints.
Overall, I’m going to give the Knog Boomer USB two thumbs up (5/5). I think it is an excellent bike light for riding in the city and the convenience of being able to charge up from your laptop is invaluable. At least as someone who is rarely away from a computer.Buy the Knog Boomer USB
- Quick to install
- USB rechargeable
- Sits a little near to your handlebars so the brake cable catches some of the light
