Smart USB Rechargeable Bike Tail Light with Brake Sensor

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.

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!

Quality better than I was expecting, really tidies up the rear and it works well.

I satisfied

I like this light, theres no dislike, auto on-off and batt. life I like the most. Very practical and useful , strongly recommend it to anyone who has a bike

I use this on a daily commutes and also long rides at the weekend both day and night due to its braking/slowing sensor illuminating like a car brake light. I charge this once a week (even though it doesnt need it) just for piece of mind, it has never died on me yet but am unwilling to try in the winter months. As for the value, I would be hard tried to find one from a well known brand for at least double the price. I have had many of my colleagues admire and then purchase themselves. I would recommend as in the pictures having a second light but its not essential (this product is the upper light and a road bike race light is the lower) due to the sensor which detects no movement and turns off the main light but will still detect and illuminate when slowing/stopping. The only issue I have with the product is the seat post attachment, although I havent used it due to it only having a hook to strap type securing, the Allen key fixing direct to the seat rails (pictured) more than accommodates this and is simple and quick to install and it comes with a tool. Again I would recommend this product.

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). Great light and worth the money.

Absolutely cracking build quality. Aluminium casing that screws onto an aluminium thread, and the brace bar for under the saddle is aluminium too. The only plastic is the stretchy rubber watchstrap type fixing, and the feet at the ends of the saddle fixing (and even comes with two spares of those).

The USB socket is nicely enclosed inside the aluminium threaded section, so water ingress is highly unlikely here.

Perfect for commuting, Ive had no problems with it so far and its brightness makes it fabulous for late night bike rides and winter weather.

Very bright ,fits on seat perfect , solid will never move. Good charge time .
