EBUYFIREBike Tail Light,Brake Sensing Bicycle Rear Lights Rechargeable Bright LED Back Lights,Waterproof Cycling Safety Taillight Warning Rear Light with Double Bracket (10, Grams)

I love this light.Finally got rid of my bag that was strapped to my seat. This device fit perfectly on my road bike saddle and it is easy to remove and install by simply screwing in our out. It has the capability to set to a flash which helps hold the charge longer and at the same time it is rechácenle, the four indicator blue lights tell you how much battery life is left. Nice and bright red led for safety where you can be spotted from a far distance.I hope they don’t stop making this product because I would want to make sure all my bikes have one for years to come. Buy it you will not be disappointed.

I wanted a small, unobtrusive, seat-mounted rear light for my mountain bike so that when I am riding on the road to the trail, I have some amount of visibility for overtaking cars.The challenge for me is that I have dropper post that eliminates ANY mounting system that attaches to the seatpost. This light attaches to the seat rails, which places it out of the way for those times I drop the seat to the collar.The light is actually working out well - the mount is solid and the light screws into its mount, making it easy for me to remove it when I have to charge it or when I don't need a light there. I also like the different light pattern options for alerting cars.

The good:Electric functionalities are well implemented and works well. Brake light is the most unreliable feature. But most important is the LED works well and battery saving automatic off is very important to me and works well too.The bad:The bracket for the under the saddle mount works only when the rods under the saddle are spaced a certain distance. If your saddle doesn't match the bracket width, you maybe out of luck. In my case, I used electrical tape to beef up the rods to make the bracket grip better. Without doing this the chance is great that the whole thing will fall while riding.The post mounting is not reliable enough to my taste. I don't use it at all.The note:Read the manual to understand the functionalities properly. The description of the Amazon page is not enough. Before I read the manual I wanted to return it because I thought it didn't work properly. The manual is printed in a very small font and not very instructive, but it is helpful nevertheless.

There were other options that would work for my bike, but I'm glad I chose this light. My bike has no water bottle bosses on the frame, so I have the water bottle attached at the seatpost, which limited my options for a rear bike light. This light allows me to still remove the bottle from the cage. The visibility of the light is also not obstructed by the water bottle. It is unobtrusive and seems well made. A wonderful little light that's perfectly suited for my bike.

Perfect light. No fit issues- I ride a santa cruz mountain bike with the standard seat and no surprises on fit. Its nice and snug. No movement. Its tucked up under the seat - perfect spot. Nice and bright. The break light feature is awesome. I even got a second one, for a buddy.

This light is excellent. Each mode is bright, and can be seen from a good distance. It can be mounted angled down or straight away. It seems to stay in place nicely too, I’ve taken it out several times (city riding). I recommend this light

Great product and I like the fact there was two different ways to mount the light. It works as should and came fully charged right out the box. Seems to be well made and very solidly built. Only time will tell in regards to the longevity of the light. The seller was great and shipped my order quickly. I received the light within two days.

Very compact and a good light. Build feels very solid and charging is a breeze. Very happy with it.

SU LUMINOSIDAD, VISIBILIDAD Y CAPACIDAD SE CARGA EXCELENTES .

The media could not be loaded.  Luz trasera muy bonita y funcional, bajo el asiento como la he montado yo queda perfecta, segura y se ve perfectamente. Bateria duradera i con indicador de estado, el puerto de carga queda completamente estanco detras de la rosca cosa que hace muy facil de poner a cargar sin gomas que molesten. La funcion de luz de freno en los 4 modos es perfecta.👌🏼👌🏼

J’ai bien aimé la fonctionnement et qualité du produit. Je n’ai pas aimé le système de livraison de UPS!

It's a good rear light, even if it only had a steady/ ordinary flashing setting I'd buy again. The clamp is robust and attaches to the underside of the seat, which is better than the rubber type fittings in my opinion. Worth noting that if you had a pouch under the seat it would clash and would probably to pick one or the other. Braking function is useful but haven't seen it in action much as obviously riding the bike and not seen it from a driver's point of view. I run with it on constant anyway and lights brighter when braking, so still visible at all times even if the braking feature didn't work as intended.

Cette lumière est fourni avec 2 types de fixation : sous la selle (crochets) ou sur une the avec adaptateur fourni.Il y a plusieurs modes : clignotantt, slow pulse, tout le temps allumé, etc... et un mode clignotant avec "extra-light" quand on freine (il sent les ralentissements quand on freine) et ça marche très bien !Il s'arrête aussi tout seul quand le vélo ne bouge plus... ça c'est top ! moi, qui oubli tout le temps d'éteindre ! ça me sauve la batterie ! et il se rallume quand on reprend le vélo !Très bonne autonomie... je recharge toute les 2 semaines (1 heures de vélo /jour sur 5 jours/semaine).Il y a des diodes bleues pour voir comment est la charge de la batterie.Étanche et petit, c'est parfait pour le laisser sous une selle !J'aurais aimé trouvé la même chose pour l'avant en strobe light pour être vue aussi des voitures qui arrivent de face. (différent d'un éclairage avant qui a pour but d'éclairer la route).
