Fantastic light

Fitted the plus rear to my D shaped seat post with no issues. Not too bright in group rides but bright enough to alert traffic to my position. Charging is too easy
Would buy again

Great product, even better customer service

I had been using the Rear Plus on my bike, but the light was unexpectedly lost during a ride. Contacted customer service and they were absolutely fantastic. James sent out a replacement right away, received it not long after. I like the light, it works well, but I loved the customer service.

'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.
