EBUYFIREultra Bright Smart Bike Tail Light,USB Rechargeable Brake Sensing Bicycle Light,High Intensity Rear LED Accessories Fits On Any Road Bikes.Easy to Install for Cycling Safety Taillights

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.

These are not the brightest on the market, but quality is good especially the underseat mounting.Fully fictional,easy fit and plenty of light options including brake light and auto off when stationary for a while.Great item, well happy with my purchsse even bought a second as a present.

It's not the brightest in the world, but isn't dim at all.I was a little worried and confused about the stay on at all times reviews as they were not clear. You CAN have the light turned on at all times without it turning itself off. Which is what I wanted. I didn't care about the other features.I chose this because of the different ways you can attach it to the bike. Especially not on the post as I have a dropper post and wanted the light on the saddle and off the post.1. On the seat post itself.2. On the saddle rails (included bracket and allen key).3. If you take the rubber band off, there's a clip to attach it to a saddle bag.The light alloy casing itself feels well made.

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.

I needed a light for the back of my mountain bike. Local retailer had nothing suitable as I have a plastic mud guard which got in the way of fixing a light in the usual position. Saw this and thought I’d give it a try. To attach it to the bike it fixes to the rails under the seat, you tighten the bracket under the bike saddle by using the supplied LG Hex Bolt and LG Hex Tool. What I found was the hex bolt were not well made. Had great difficulty in tightening them. I would suggest if better quality hex bolts were used this would solve the issue. It does have the ability to attach the light with a rubber strap, I’m not sure I’d trust that long term. As for the light, it’s bright, has several flashing modes. As any cyclist will tell you, you need to be seen at night, I have no doubt this light will be seen from considerable distance.I can’t review how long the light will have power once charged as I only received it today. The manufacturer claims after 2 hour charge it will last for some time. The light unscrews to make it easy to recharge and take of the bike if leaving the bike. The box says the light responds when you break, I will try this when I have someone out on a bike ride with me and will then update this review. Instructions, ok chinaenglish lol. Gauranteed it says for a year, we will see. Finally at minute, I’m happy with it.

Excellent. Easy to fit under the saddle and bright. Brake light function works well.

Very solid and very neat design.The bolts allow for a robust mounting on the structures of the saddle. Everything could be stolen, in theory, but if you leave this on the bike once mounted to the saddle it would be quite hard to be clipped away. The light is quite bright and the different settings can be chosen simply pressing the silver dot.Easy to unscrew and recharge. Good value for the money.
