Backlight smaller band needed

I have a carrier with 6 mm framing. No bracket for a rear tail light. A smaller band to cover this would be good.

Great functionality, weak points in the physical design

I’ve been using these bike lights for about a year and a half and I love them; they’re bright, the different modes are great, the battery life is good. Their only weakness is the plastic around the charging tip has very quickly broken on both lights, making them extremely hard to charge. If that weakness in the design was sorted out they’d be an easy 5 star product :)

Excellent light! Straps may need revisiting

Such a good light, unfortunately the strap broke after a few weeks of use. Not sure what to use now and haven’t ridden my bike since

Light is average. Battery life sucks.

Surprisingly bright

I was a little disappointed when it arrived as it is so small, however its size is deceptive as it’s very bright and versatile due to its clever design. The instructions are basic but it’s easy to figure out how it operates and it clipped easily and securely onto my kit bag. I have a habit of losing lights but I would definitely replace it with another Knog.

'a beautiful and functional design, coupled with purpose and power.'

‘4.5 / 5 Stars. Knog Plus lights attach easily and unobtrusively to the bike. But they can also be worn on clothing, making them very versatile... and the run time is good for such a compact unit.’

Knog's Most Versatile Light Ever.

Simple, effective and packed with features that make it a pleasure to use.

Latest COB Technology

Efficient Chip on Board (COB) LEDs provide maximum brightness level for up to 90% of the battery burn time.

Integrated USB Connector

Plus plugs directly into USB-A ports & is designed to be exposed to the elements. Just remove from it’s magnetic mount and you’re ready to charge.

Charge Indicators

When Plus is running low on battery, a red ring will light up around the button. This ring will also show when charging, and turn off once fully charged.

Mount It Or Wear It

Mount on the seat post, seat stay... anything goes. Or remove from the mount and it now doubles as a wearable running light or versatile camping light.
