BKS-G5

Great light nice and bright, I like the fact it just turns on and off on its own. My only concern if you dont have a open slot to mount on bike rack it gets interesting mounting on existing fenders, The mount holes line up but you cant bend to the curve of fender (longer screws resolves this for the most part)

I installed one of these on my bike prior to a week trip at the coast. I also talked a friend into getting one as well. He was bummed at first as he said that it didn't turn off for putting on a rack as other reviewers had also mentioned. I showed him the 5 position button that ultimately turns off the light for traveling. So we both had these lights on our bikes and went for a few rides and we were impressed how quickly the brake light reacts to braking or even slowing down. The auto shutoff is great for short stops at restaurants or stores as you don't get halfway down the street and realize that you forgot to turn on your taillight. The only time that I turn mine off now is just prior to putting the bike back on the rack for the drive home. Excellent light!

Hello there! I’m an e-bike owner. I bought this rear tail light for my e-bike, it’s a Vivi ACE01 E-bike. This is the only light I could find with reasonable ratings and a reasonable price. For those that own a Vivi ACE01 or have the exact same reflector tail light, then this light is compatible for your bike. The box came packaged correctly and was well sealed. I took it out, charged it and set it up. It’s easy to setup and install, if you’re curious, no, it does NOT come with an AirTag, you got to buy that separately or from Apple. So once it’s installed, you’ll see a big hole where the Apple tag goes. For functionality, the button isn’t a soft push button, it’s hard to push. You have to give it minimal force, slightly, just to turn it on or switch modes. The brightness, it’s DECENT. But not BRIGHT enough. If you want something BRIGHT, then I wouldn’t recommend this product for that. I’d say this light is just enough for people to see you maybe 200 feet away and that’s it. Stability is perfect, no issues with it. California roads are insanely bad, so it works just fine, 0 issues. I’ll be back next month to update my review on everything such as battery life, durability, etc. Thank you for taking the time to review my review.

Just awesome rechargeable and very bright Different displays and adjustment switch easy to see and use..! Highly recommend for the money..! HOME RUN..!

It works. It doesn’t sense when you stop automatically every time but I didn’t expect it to. I more or less just bought this because it fit the application i needed it for. I just wanted a taillight for my Surron ultra bee. I needed something basic just to give me self a chance to be seen on the road by drivers. This by no means replaces the OEM Surron Street legal light kit but if you don’t want that big bulky light kit and are just looking for something basic so other drivers can see you this is perfect. I paired it with a $7 bracket and bolted it to the bottom of the seat on my Surron. I used the bolt holes that were already there. Very basic but it works and it looks great. I’m just concerned that it might fall of its own bracket during a jump or road vibration so for that I applied Velcro to the back of the light. It’s the best solution since you have to take it on and off for charging.

This light was MUCH less than the type that the local bike store carries, and it works great with several light settings to choose from. It was very easy to install and looks like it should be pretty adaptable to most type of racks. The light also easily removes to take inside to charge, but the coolest thing is the light has a built-in spot for an Apple AirTag, so I can track my bike down if it gets stolen. Overall, I can recommend this taillight!

This used to be a great rear light until they changed the mounting bracket. The one's I bought over a year ago are still securing perfectly. Unfortunately, the manufacturer changed the mounting bracket and it does not hold the light securely at all. I tried ordering another one... same bad mounting design. Please change it back to the old mounting system. The fourth bike in our family is waiting for a rear light.

This smart light is great. It illuminates my backside and makes me more noticeable with cars. No need to configured, it automatically works, just select one of the blinking patterns. It also detect you slowing down, and lights up to alert other you are slowing down. This doesn't work perfectly as there's a 1-2 seconds delay. It has a good battery life, so I don't need to charge for two weeks or more for my 20 mins commute each way. I can easily remove it for charging. You have to remove it for charging unfortunately, and one time, I didn't mount it correctly and it fell off during mid ride. I am glad I heard it drop, but no damage. Wish it can be charged while mounted, so I don't need to mount unmount. Also, it is very expensive compare to other with the same or better smart lights. Other than that, a very solid smart bike tail light.
