Weighing little more than a handful of paper-clips Knog’s Frog’s are surprisingly bright miniature LEDs, ideal for contingencies and complementing ultra compact Li-on lighting systems but fall dangerously close to the trap of being style over substance-especially compared with their Bullfrog siblings.
Encased in medical grade silicone and available in a choice of twelve colours to complement or contrast your bike’s livery, these stretch fit securely around most handlebar and seatpost diameters-or if you prefer, fork legs and seat-tubes. Minute dimensions and clever styling prevents them spoiling a race bikes’ clean lines and they’re a delight to use even wearing winter weight training gloves thanks to positive switches. However, despite claimed visibility of up to 600metres, single beams lack the presence of larger designs and the latest generation of micro lights.
Build quality is definitely up to the firm’s usual standards-our pumpkin coloured rear unit came unexpectedly adrift at speed, taking quite a knock as it hit the asphalt but mercifully, bulb and internals remained completely unscathed. This is largely attributable to the silicone casings, which, while not waterproof in the literal sense, shouldn’t succumb to the elements anytime soon. Burn times are pretty faithful to manufacturer claims, our test pair managing 77 hours in constant and 156 flashing modes respectively.
Ultimately, style conscious riders wanting beautifully designed emergency micro-lights for late summer/autumn evening ride contingencies won’t be disappointed but others within the Knog range and elsewhere represent better value.
Very stylish, pretty lights but form outweighs function.

Size tested: n/a
Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
The Knog Frog's are good looking, tactile micro LEds designed to appeal to style concious riders wanting ultra compact Led safety lights.
Tell us some more about the technical aspects of the product?
Encased in medical silicone and in a choice of twelve different colours, there's pretty much something for everyone here and they are as close to universal fit as you'll find. Claimed visibility is 600m from a tiny single bulb and long run times (80 and 160 hours) in static/flashing modes respectivelt is broadly accurate.
Tell us how the product performed overall when used for its designed purpose
As a micro light they consume nominal bar space, don't clutter a minimalist bike's clean lines and are very pleasant to use but the tiny beam while undeniably bright, lacks the outright presecence of other designs.
Tell us what you particularly liked about the product
Tactile, tiny and very, very stylish.
Tell us what you particularly disliked about the product
Form just wins over functions and their bigger brothers, the bull-frogs make much better secondary illumination-albeit consuming more bar/seatpost space.
Did you enjoy using the product? Yes
Would you consider buying the product? On balance, no
Would you recommend the product to a friend? Possibly
