Sunspeed LED Rear Bike Light - USB Rechargeable and Super Bright - 6 Light Modes - Easy Install & Quick release - Water resistant - Increase Safety & Visibility

The light is great, multiple settings and the battery life is great for my needs. All this does not come with its flaws though :i) Firstly the rubber grommit that sits over the charging port came out fully after just carefully opening it for its first charge, impossible to get it back in. Which now results in me having too place a bit of sellotape over the port each and every time after a charge, just to make sure that no water gets in.ii) The rubber grip that holds the unit onto your bar/pole is very subjective to breaking, and my biggest piece of advice i can give is to leave it on once you have it on. And then just use the quick release system clip to remove the light when needed too.iii) No battery indicator, you have to kind of just get a feel for how long its going to last with the settings you use. For me i can get 2-3 charges out of my front light before having to charge this rear light.Overall though ive been happy with the product, great price for what you get, just a shame on the poor Quality Control on the aforementioned pieces.Edit: I have been in contact with Customer service concerning the above problems i have been having, and i must say its been 1 of the most enjoyable experiences i have had. Fast response times and actually someone who is not just following a script and was actually useful. I was sent a replacement unit free of charge (granted it was a non working unit) so that i could salvage the parts that where needed. So top job for the rep that dealt with me. It was all greatly appreciated.And a tip for those that also get any issues with the rubber grommet coming out - get yourself a paperclip and use that too push it back inside. Seems to be of adequate size to do the job ;)

Have used Sunspeed front lights for the last year and wanted to get a brighter back light- this did not disappoint. Super bright, with flash mode, I feel much safer on the roads knowing drivers can't miss me.Pros: extremely light and quite slim so great for performance. Quick to remove as well, and of course, super bright. Got plenty of modes but I keep it on fast flash. USBC chargeable with standard cable (great if you have an android phone). Can go horizontal or verticle depending on your preference. V easy to attach too - no bolts.Cons: haven't had to charge it yet so don't know how long it lasts... at least two weeks so far!Highly recommended from me.

VERY bright, easy to fit and charge.Various modes: constant, flash, variable, and speeds.Various illumination levels: dim, normal, bright, Super bright.Charges via the supplied micro usb connection (quite quickly) and has a low battery warning indication too.Easy to fit; supplied with quick release rubber stretch wrap strap, (so fits a wide range of tube bar sizes), and the light unit itself can also be removed from the rubber strap via quick release button.The running time varies according too the illumination mode used (dimmer/flashing lasts longer) but even on the Super bright constant mode will last for hours.Full clear English instructions provided.(minus one point as switching off is a bit of a timing button press between the illumination modes, but easy once learnt- what ever happened to a on/off switch?)Overall this is excellent. When in Super Bright mode it really can genuinely be clearly seen from a very long, long way, providing good visual protection.I WOULD recommend this product.

I have been sent this rear bike light by sunspeed a week ago for testing and am very happy with it so far. It was easy to fix to the bike and gives a nice, bright signal. It was a bit tricky for me to switch between normal and flashing mode (I often turned it off accitentally instead of getting it to flash) at the beginning, but now I can get it to work. The light was quick to charge and so far, I didn't have to recharge. I would certainly recommend this product.

very happy with purchase, nice well made light which can be mounted very easy,this light is very bright, have only used for one day so cannot comment on length of time it last on one charge but cannot see that being a problem.UPDATE, LASTED JUST OVER 12 MONTHS THEN PACKED IN, ONLY USED IN WINTER MONTHS (UK) SO YOU COULD HALF THAT LENGTH OF TIME, WOULD NOT PURCHASE AGAIN.

Not as good as another rear light I bought.The on/off button is too fiddly. The one button is for on/off, changing mode, intensity of light. Idea is good. Difficult to get the light to the level required. The light quality is not brilliant.

This light is fantastic and bright with a long battery life, when it works. one of mine keeps turning its self off even when fully charged. Trying to contact the seller to get a replacement is proving difficult as i cant find where. So im writing this review to get their attention for help,

Light works well but the rubber plug on the recharging port came off as soon as I opened the packaging and is impossible to put back- disappointing. This product won’t be water resistant.
