Smart Bike Tail Light USB Rechargeable Bicycle Turn Signals with Remote Control Rear Bike Light Waterproof Safety Warning Back Lights Bike Alarm for Night Riding Mountain

This is a nice little unit. I cycle mainly on track, which is floodlit at night. Even with the floodlights, I realised that it’s difficult to see other cyclists at a distance, so decided I should get done lights as a courtesy to others, so they have an awareness of my presence! This is a nice little unit, with a nice solid, quality feel to it. It comes with a choice of fitment - a fixed bracket which clamps to underside of saddle on the metal rails, or a mount with rubber strap to easily attach/detach it to your seat post. I went for the saddle mount as it is out of the way and looks tidy. A nice touch is that they provide a hex/allen key to fit the clamping bolts - Nothing fancy but it does mean you can fit it without searching the garage for the right size hex key! The main unit itself is a nice alloy construction and has a USB C charging port on the back. In use the unit screws on to either the saddle mount or the seat post mount. The thread is very fine so takes a quite a few turns to fully tighten it and there is an O-ring seal which keeps the water out from the charging port once screwed in. I can’t imagine it will come undone by accident in use. The different modes are good and accessed by pressing the metal button in the middle of the light - flashing; breathing (I like this one!); a fast triple (I think) flash; constant on. The accelerometer that’s built in appears to work well, so that when the bike suddenly decelerates under braking, the light comes on solid and bright and stays on for around 3 seconds. I can’t tell if it stays on bright all the time you are braking (like a true brake light on a car or motorbike would do) as I’m likely to fall off the bike trying to work that out. If I can find a friendly cyclist on the track at the same time, I might ask them to watch for me and let me know - I’ll update this when I find out! Basically it’s great value, feels decent quality and does what it says it does.

Unaccustomed as I am etc to reviewing kit - I will heartily recommend this light for all willing to lend and ear. Beautiful designed, beautiful light quality in terms of clarity, luminosity and colour (yes, seriously - wonderful shade of red), easy to attach (seat post in my case), easy to unattach, easy to recharge (USB cable), and easy to toggle between 4 light modes, and a handy indicator for battery strength (4 tiny blue leds for fully charged, counting down to 3,2,1). Plus I love the brake indicator - where it brightens strongly when firmly decelerating. I'm unsure about overall battery life, or replacing the battery (hopefully it'll be both long-lasting and easily replaceable) - but it's got me safely through the long, dark Winter months (Nov - Feb) - and hopefully many, many more to come.

This is a well made rear light for a bicycle. The bracket is fine in my experience. It fits discreetly under a saddle, subtle blue lights tell of its charge status, there is finesse in the design and it is admirably put together. Is bright in my opinion, with braking light very noticeable. The instructions could be better - it has 4 modes, and, I believe, but can't be sure, that if in the first two modes, in daylight, if the lamp goes to sleep due to inactivity (or smooth tarmac !) it stays off. That is worrying. I have returned from a ride to find this. The 3rd mode (flashing) and 4th mode (constant) do not have this problem, I only use these, is always on when I return. Considering all things, this is remarkable value and and a joy to use.

Went for this in all honesty over the price of more expensive branded items as i thought it would be a fairly good light for the money, for sticking on the bike to ride to/from work or on any evening commute. But this has proved to be an amazing light and couldn't recommend it more! Very simple to install and very minimalist once on the bike, you can fit the saddle mount (which is made from cast aluminium and extremely strong) bolt it up nice and tight and just forget about it as i'm confident it will not budge. The light then simply screws on and off for charging and is a wonderful threaded fit into the mount, and the o-ring seal feels nice and snug. I'm not one to write reviews but definitely knew i had to spread the good word about this. Very well made and seems like it will last me a long time to come. The instructions aren't the best, but it's one button to control the whole light and 4 indicators to see the battery percentage...so it's a doddle to use. Couldn't recommend more!

2nd review as lost 1st. Awesome light (read rest of review) only issue is I have E13 dropper & it loses grip pretty quickly when rail mounted if hitting jumps/dh trails. Probs my own fault for using when hitting trails, but absolutely amazing (if you remember to remove it 1st 🤔😆) Fantastic product, good brightness & excellent brake sensing. 4 easy to select modes. CNC build & rubber o ring to help waterproofing. 2 different mounts provided, both very good & hold light solidly even when offroad. Very similar to Rockbros Q5. Don't just think about it, do it. It'll be one of the best purchases you can make The fact I bought it twice says everything imo

This is a great little light, I specifically bought it for the seat rail mounting as it is a pain removing the light every time I fold up the Brompton. The clamp fits perfectly on the Brooks C17 saddle allowing the bile to be folded easily. As a rear light it does everything you might want I am unsure of the utility of the brake light feature but it does no harm so it is a bonus addition. My only gripe is with the "manual" as the print is very small and I am still a little confused by the different modes and how to trigger them. It would also be helpful if the manual mentioned that the active part is a screw fix into the bracket(s). Shipping with both brackets types is great as I can now swap the light between my Brompton and my proper bike. Great light and worth the money.

Great little light it’s so bright for it’s size and when you break it lights up like a stop light

Stopped working after 6 months of barely being used. Turns on but goes off after a while which is clearly dangerous when out riding after dark. Took this up with customer support to find that you only get a 30 day warranty. Nowhere does it say this in the product description. Feels good, looks good and even feels good quality but clearly it isn't. And you really need to rely on and trust your rear light to know that it is working. My advice is to but something better with a warranty.

The product is not as bright as I would have liked for day use, but plenty bright for night use. The brake light functions fine, the real victory was fitting it to rear bike rack of Engwe bike. I had to cut, then bend a light flat bar of aluminum to attach to bike. The saddle and seat post attachment were no use to me as I often carry panniers and luggage on back of bike. Will update on light itself once I've used it for a while.

I don't know why I didn't get one of these sooner! It auto senses when coming to a stop. Multiple flash/strobe modes, easy to navigate modes, and when you brake it goes super bright. Great for cyclists behind you and for cars. The build quality is surprisingly good, almost a little too heavy - wished it was a bit lighter if anything. Two ways to install it, underneath the seat or on the seat post. Overall very happy with the product.

Il fanalino definitivo, lo uso in MTB cross country da 6 anni, installato sotto la sella, ancora perfetto, molto luminoso, si accende da solo con il buio, lo ricarico una volta ogni 2-3 mesi (ed io torno quasi sempre dai miei giri 1-2 ore dopo il tramonto uscendo una media di 3 volte a settimana), in alluminio molto resistente, si avvita sul supporto in modo molto sicuro, sono 6 anni che resiste a tutti i miei scossoni in MTB.

Beste achterlicht ever. Nacht / dag schakeling. Remlicht. En batterij gaat lang mee. Ik ben content
