Fabulous Frogs

My eBike has lights but I wanted some flashers to make sure I was noticed. These things are brilliant. So easy to use, charge, and install.

A classic gets even better

After a multi year break from cycling, I’ve just got back into it and if course had to buy mostly new gear, including lights. After much research I settled on the Frogs for a number of reasons (USB-C charging high on the list).
While waiting for the lights to arrive, I came across my old lights, only to discover that my previous rear light was actually the original version of the Knog Frog! Great to see them going strong, and still making quality gear.

They work great👍

'the bike light that changed bike lights forever.'

An icon re-born.

Brighter and better than before.

COB LED Technology

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

Advanced Side Visibility

COB technology allows the LEDs to be arranged on a curved board, projecting light from the sides & adding to rider safety.

One Button Operation

A single large, easy press button makes the operation of these lights super simple, even in gloves.

Integrated Flexible Mounting System

With no tools required to mount Frog and featuring an integrated flexible strap, Frog is easily mounted anywhere.
