SEEMEE 50 V2.0 Bike Tail Light | USB C Rechargeable, 50 Lumen, IPX6 Waterproof, FTR Cycling Safety

The light fits well on my bike. Going over multiple bumps, not once has it fallen off. The light is easily seen and the battery life is more than sufficient.

Nice and bright. Visible from at least 180 degrees. Battery life is good. Fits my aero seat post, but just barely. I do wish the charge port was accessible without removing it from the seatpost. Maybe a little pricey, but overall I am satisfied.

Light is very bright and the battery life is pretty good. It has a few different modes depending on brightness or flash pattern. It’s not too difficult to attach to the bike but can be a little tricky depending on the thickness of your frame

I found it had to find a vertically mounting bike light and came across this. It is very bright and fits the bill. It’s also a nice portable size making it easy for me to move across a few bikes. I especially like that it is UsB-C charging which so many bike lights still use Micro.

I use it in my helmet with the supplied rubber strap. Looks awesome and is highly visible!

This was purchased the day after I received the Hori 900 Light with FTR Remote package that I really like. The trio was for use on the GAP trail, but planning on seat post placement when I got off trail. It charged quick, is bright enough without be blinding, and pairs with a remote (no more stopping to turn it on). For the trail I attached it horizontally (Angle of Visibility surface is lost) to my trunk bag, but was able to lift the bag by the light so I was confident all was good to go. On the last day I reinstalled it and after about 12 miles, I discovered it had fallen off. I'll take partial blame, maybe I wasn't diligent that morning, or the silicone strap was never meant to be used that way, who knows. Still highly recommend the light, but for post or frame attaching only! It loses a star because the charging port cover kept popping open, probably because its not pressed against something.

Perfect in every way@!

I’ve been looking for some smart lights. I really like these so far. One switch in thumb reach turns on rear and front lights wirelessly. Working good so far.

Magicshine always makes great lights, with so many different options to suit your needs. It has many options for brightness or constant vs. flashing. They offer many mounting options - this one mounts to your seatpost. Just a warning, if you have anything mounted to your seatpost e.g. an underseat bag or a rear rack, this light many not work for you. But overall it charges quickly and works well, with good battery life and solid construction.

La fixation se fait par un élastique

This little (it's only about 2.5 in long and so narrow that it hides behind the seat post) tail light is really bright! Thanks to the cleverly designed LED layout and a reflector cover, the light is not only visible from the rear, but also from the sides and even 45 angle to the front of the bike! Maximum output is listed as 50 lumen which is actually really bright, although this power is only achieved in the daytime flashing mode which turns the light on for a short, but really bright blink roughly once a second. In the low steady mode the light puts out 6 lumens and the battery should last almost 7 hours. In the high steady mode (just under 4 hours) and night flashing mode (7 hours of battery) the output is 15 lumens which is still very bright. The night flash is a pulsing mode where the light cyles between low and high ouputs - very good mode as the light is never off - even when someone's eye just goes over the cyclist in a fraction of a second, there is no chance that it will be mid blink when the light is off. For longer events or when you are away from a charger, there is also an low power flash mode - two dimmer flashes followed by a bright one which will keep the light working for about 30 hours. If you own more than one of the SEEMEE 50 lights, then when used on a ride together they can synchronize their flashing patterns in a pelotonsync mode. As far as I can tell the light doesn't sync with other models of MagicShine tail lights. When it's time to recharge the light will charge from any USB-C source. The charging port is neatly hidden under a thick, rubber flap. The light mounts to the frame with a thick elastic band. It can be mounted on a seat post but the band also will accommodate a thinner frame or bike rack element. It's secure and yet easy to remove for charging. One thing to note is that the mount doesn't correct for the seat tube angle so when mounted there the light points slightly down - I don't really think it's much of an issue, as the beam is very visible even when viewed at an angle. Overall, really good light, small yet very bright. Super light, you could probably figure out how to mount it on a helmet and you wouldn't even know it's there. I've noticed that the price of this light fluctuates quite a bit so check for sales.

marche super bien !

Cette lampe de vélo est puissante, compacte et légère, facile à glisser dans une poche. Avec ses 50 lumens, elle offre un éclairage efficace et sécurisant, visible de face comme de profil. Elle propose cinq modes : deux fixes (intense et moyen), un « respirant » et deux clignotants (régulier et alterné). Elle mémorise le dernier mode utilisé et son autonomie varie de 3 h à 30 h selon le réglage. Les matériaux sont solides et de bonne qualité. Mon seul reproche : la fixation par simple élastique, facile à retirer et donc peu sécurisée en ville. Une attache plus fiable aurait été préférable, d’où la perte d’une étoile. Certains apprécient ce système rapide à installer ou enlever… mais c’est précisément ce que je lui reproche.
