ONVIAN 2000 Lumen Bike Headlight Rechargeable, 4 LED Bike Light Modes for Night Riding, Sturdy Aluminum Alloy Installation for Bicycle Snowblower 4Wheelers Cycling MTB Headlights Handlebar Accessories

Excellent build quality

Put this on my bicycle which already was equipped with a light but this greatly improves what I'm able to see when riding shutting during the night

The USB-C port on this light is bad. Very bad. Dangerously bad. At first, I found it wouldn't charge with a USB-C supply, which is unfortunately very common and indicates the manufacturer went cheap end left out ten cents worth of resistors. Without these resistors, this light will only ever charge with a USB-A to C cable (included), as it cannot ask a correctly implemented USB-C/USB PD charger to provide power.That's bad enough, but it gets worse. I found that the USB-C port on the light is OUTPUTTING 5V ALL THE TIME. Even if this were a charger, that would violate the USB PD specification as mentioned above. This light isn't even marketed as including power bank functionality! You cannot safely plug this into ANYTHING, as it will backfeed power and potentially damage your charger.I am completely flabbergasted. It's unbelievable that the designer/manufacturer could mess this up so badly. This is a complete dealbreaker, and it's really a shame because it's otherwise very good.Now that I have that horror out of the way, another small complaint is the mount. Out of my bikes, I was only able to mount it to one of them. The included plastic shims are either too big or too small for my other bikes, including an old MTB I use as a commuter. The diameter of the bars this won't fit are 25.4mm and 26mm, both very common sizes. (I'm mounting right near the stem clamp.) The bike it does fit has 22.2mm bars, and it would probably also fit 31.8mm.It's really a shame, because the light itself is very bright, the reflector designed very well, and the housing is quality. I just cannot recommend ANYBODY buy this with how terribly the USB charging is implemented.

Works great I'm going to order another one for my other bike.

In terms of lighting stuff up, this light is plenty bright.I like that you can slide it off the bar and take it with you so it won't get nabbed.I do have a few quibbles with this light, however.First quibble: you click once to turn the light on medium and ride. When you get where you're going you now have to click again for low, click again for high, click again for blink, and then click again for off. Why not just have long-press for off? It's a picayune complaint, but it's an honest complain.Second quibble: it's a tad heavy toward the front. I found that after going over some rough pavement in the city I would need to pull the light back up. Maybe that's me not tightening it enough, but I thought I cranked down on the screws pretty good. Meh.

This light is actually bigger than I thought it would be which is nice, it's for sure super bright. I feel like bike lights have come a long way since batteries are getting better. Would highly recommend for the price!

I don't recommend this because it's very heavy, and the mounting bracket is not that great. It's also a very weird design that takes up a lot of room on the handlebars due to the width. It is fairly bright, though not very balanced (a bright spot in the middle, rather than a wider, more even beam). Overall, it's about average quality, or maybe a little less. I don't recommend it, but it does work for some purposes.The promotional copy also leads me to suggest avoiding this brand, as it makes little sense and doesn't seem to show real care and love for their product. For example, this random sentence in the middle of the details that doesn't relate to anything else that comes after it: "It's hard for riders to keep their bike light from falling out of their backpacks." What? If they give this little attention to what they say about their product, then what does that say about the attention they give to deciding what product to make/sell?

Easy to install and fits perfectly. The light is bright enough that riding at night is not an issue. Cars are able to see me easily and I can see any obstacles on the road.
