CatEyeRapid X3 Rear Lights and Reflectors, Cycling - Black, NO SIZE

Excellent battery life, lasts a really long time and I love that they recharge (quickly) by micro USB.They give out a really bright light, and there are various settings including a few various flashing options. It quickly attaches to the bike using a rubber 0 ring, I was a bit worried about this to begin with, but I've used it regularly over the past year or so and have had no issues at all.Highly recomended, excellent performance and will worth the money.

Pros- its effectively 2 lights in one. Has 2 seperate LED strips contolled by seperate buttons. So you can have different light combinations. I tend to have one side still and the other flashing or pulsating (best of both)- lots of different lighting modes- easy to mount- extremely bright! Most of my riding is at night and im the noticing cars comin up behind me are slowing down and giving me a wide berth when overtaking. something im not used to and makes me feel much safer on the roads.- Goes into power save mode when the battery is low which lasts upto 30 hours.Cons- The mount is not a mount but a tough rubber band which wraps around the frame and attaches to the light. Cant see it lasting more than a year or 2! (Or ill end up losing the band before then) Would have much prefered a proper fixable mount especially At this price point- buttons are a little fiddly to operate.- its quite expensive.Not had chance to properly test the battery life so I wont comment on burn/recharge times.Seems like a good light overall. Offers lots of visibility but let down by a cheap mounting option.

This is a great light and CatEye know how to make great bike lights. Many functions and at its brightest very bright. Works well with ordinary and aero seat posts. Some criticism in the reviews of how easy it is to turn on and off - ignore them. It is very easy to operate. Some comments on waterproof. I have bought three of these, one for my son’s bike and two for mine. Don’t leave it on the bike when you are power washing it. If you commute in all weathers I would make sure the usb socket is facing down and maybe double check the rubber grommet is in place. Some will scoff and there are certainly more water proof lights on the market, but the brightness of this and the light choices, in my view make it well worth it.

Expensive but well made USB rechargeable rear light. I purchased this to on the back of my recumbentvtrike with the rubber adapter it fits with the o ring to the tube on my pannier rack thinking of buying snouther it's that good not been happy with cat eye rear light quality before but this has made me think again I have a dynamo rear light and this is a great 2nd light for me works well in daylight too which is what I wanted

While the light is nice and bright, with a good choice of different settings it has two major failings which mean it is FAR too expensive for what it is and indeed barely fit for purpose.1. The rubber band mount. Should this either perish or come off for any reason you'll likely lose or break the light. When you're paying £35 for a light it should come with a proper fixed bracket.2. The rubber cover for the USB port is not tight fitting enough. During the first British winter using the light, it has filled up with moisture (the inside of the light is foggy with condensation) presumably due to the loose fitting cover. The light now does not work reliably (will not switch on) on a very regular basis.I purchased this at the same time as a Cateye volt 800 front light, which has a very good USB port seal, so it isn't like they haven't solved this problem...albeit on a front light almost double the price...

A really excellent rear light - very bright, plenty of options, long battery life and quick to charge up. Very happy with performance.

A great rear light. The only slight flaw is having a rubber "O" ring to connect it to the rack adaptor

I give it 5 stars because I can't fault this lamp for what it is: an overpriced and overperforming rear light. I wanted the best, but frankly I realized this is too much even for my quite high expectations. This is literally 2 lights in the same housing (you can independently operate the two) and just having the half of it would be totally sufficient for all practical purposes. I can only see the need for such a light if you bike a lot in fog and rain. This is practically a daytime fog rear light for bicycles. The brightness is similar to brake light on cars. In clear weather the strongest setting is way to bright for night and more then bright enough for daytime. It has multiple flashing/pulsing modes - too many if you ask me. I also have the X2 which is a brake lamp that is useless. The X1 may be the best option, although it has significantly less lumens.

i 150 lumen fanno la differenza per una ottima visibilità anche di giorno.

Like all the modes and this thing is quite bright - good for daytime rides.

Comme le commentaire précédent, ce feu arrière est super il signale parfaitement la présence du vélo et dispose de plusieurs puissance d'éclairage.

・明るさかなり明るいです暗い山道でも後ろの車は見つけてくれると思います・耐水性土砂降りでも大丈夫ですUSBケーブルの差込み口のカバーはしっかりフィットしているもので水が入ってこないようになってます・バッテリー持続時間明るさ最大の時間を見るとあまり長いと感じませんが明るさを1つくらいさげても充分明るいのでバッテリーを温存して使用することができ長い間走行できます
