Knog x ef plus rear light

Awesome light weight bike light. Mounts are super convenient and great for clipping on to the back of your jersey, belt or bag. Will definitely be grabbing a back up or two!

Great little light

Easy to fit and being small gives plenty of options for placement. Was concerned that it might fall off my hardtail MTB when going over really rocky terrain but it stayed put.

Only small gripe is I can tell how charged it is, as there is no indicator.

Great lights, but...

They are great, easily removable, but after a year or two the battery is gone and there is no way to switch the battery resulting in e-waste.

Great Compact Light

Haven't used a lot yet, but happy with the form factor and performance. I think these lights are well designed and versitile which is why I bought a second!

Grate little light

Grate light, would definitely recommend but if you clipping it to something I would use one of the rubber bands that come with it around the open end as the clip is not that secure.

Great Product

The rear light is small and mighty. I love that I can clip it on the back of my jersey pocket instead of attaching to my bike. The light is bright! Great product.

Getting a lot of compliments on the color of the brake light. So far it's been great at Central Park during the night

Fell off the bike

Fell off my rear bike rack on my first bumpy gravel bike ride. The cheap rubber band mount was both a pain to get on/off, and not secure

Super top👍

Très bien sauf que les connectiques pour les recharger sont pas fournis avec, heureusement que j'en avais déjà d'une précédente commande 🤷 ce qui m'évite des FRAIS OPTIONNEL supplémentaires 😤
Sinon le matériel fonctionne très bien, malgré un rappel de sécurité ( dont mon numéro n'est pas concerné 😮‍💨) je suis satisfait de mon achat 👍

My mistake remedied by Knog

I bought one of these and it is, indeed, very bright. However, I bought the wrong version and bought the version that's simply for clipping on, not the bike version that mounts to your seat post, or elsewhere on your bike. However, Knog supplied the missing mounts free of additional charge to me. I was very happy with this response from Knog!

Oi classic bell is simple and beautiful. Got a couple lights for the town bike as well and love the look. Thanks!

Great bike light

Love this bike light. Super bright, super lightweight, great presets, really easy to charge.

My only criticism is not about the light, it's about the straps. The straps work great on my standard cylindrical seat post, but I have to combine the two straps in order to fit the light on my aero seatpost. Would appreciate a larger-sized strap to make it fit easier to large, non-cylindrical seatposts.

But otherwise it's a terrific bike light and I've recommended it to all my friends

Great little light

Great little light. My first one lasted almost 2 years before it stopped working. Replaced it but on the first ride my new one fell off. Had it in the same location as the first one and rode exactly the same routes. Must have just been a dud magnet on the 2nd one.

generally satisfied

I'm generally satisfied due to their practicality and versatility. However, there are some drawbacks: The battery doesn't last long, especially in constant mode, which can be a problem for longer rides.The magnets can easily get lost during clipping, rendering the product unusable on a bike once they're gone.
While these lights are convenient and well-designed, their battery efficiency and magnetic issues need improvement.

Nice small light with a decent batterlife. Like the magnetic fiiting to the brrachet and intergrated USB charing port. Simple, effcetcive and well dsigned.

Long-lasting battery

The battery lasted a long time in blinking mode. However, the magnetic part rusted badly.

The brake light that could have been

The light I needed was for my new nightly ride. The light I got was good until my bike fell over and the plastic band snapped off. I don't blame knog for this but it was unfortunate that I had only a few days with it before date got a hold on it. What I will say is that the USB charging is good the light was strong and the settings were easy to navigate. I would buy another again just not right now

Compact and bright

Works very well on my recumbent trike! I have it attached to the seat stay.
