DON PEREGRINO M2 Rear Bike Light up to 90 Hours Battery Life, Bicycle Rear Light USB-C Rechargeable with 5 Steady Flash Modes Bike Rear Light

I have had many rear bike lights in the past and they were all a heap of junk, all battery operated and most so cheaply constructed that they fell apart within months, I had a couple that just fell off, mid ride; I left them in the road, I was glad to see the back of them, to be honest. Then along came this little baby! This has no batteries (hurrah…batteries, eurrkk, SO last century) just power it up with the USB port, is super bright, has a number of different flashing light settings, is easy to attach and take off and was under £20. I have only purchased it quite recently so I am not sure how long each charge will last but as long as I can get a week or two from a charge, I’ll be happy. It has a rubber strap that needs to be attached which is a little bit fiddly but once on it can stay on for good as you can still access the charging port with it in place. The light has a clip on the back so if you leave the rubber strap off you can just clip it onto a rucksack or similar, which may be useful for some people. I have included a number of pics which will make most things self-explanatory. The method of attaching to a bike is the rubber strap and a little metal S clip that hooks into slits in the rubber. It seems to be quite solid once on, but you do have to stretch the rubber to hook it up…only time will tell how long the rubber lasts. If this one falls off mid ride, I will be stopping to retrieve it, pronto! As I say, the photos should make things a lot clearer than my ramblings, but so far, I am a really happy bunny. Oh yeah, and to turn it on and scroll through the different flash modes you just push the button in the centre, to turn it off, push and hold, easy peasy, lemon squeezy.

I bought this M2 in July 2020. Used it for about 3-4 hours per week on the Flash mode. Battery is excellent and better than any other rear light I've had. Other rear lights (the long thinner ones) lasted about 3 hours in total.It says you'll get 90 hours of use from using it on Flash mode. I can't vouch for this, but I can say it has gone on for over 15 hours before I've charged it - and not because it has gone out, but because I didn't want to risk it going off on a ride, so it could have gone on for many more hours.The brightness is perfect. Something about the LEDs' arrangement and the translucent white cover just make it very catching on the eye, particularly on Flash mode.The strap is clever. It has two asymmetric rubber pieces on its inside that mean when you attach it to your seat post, it sits nearly vertically, rather than at the same angle as your seat post i.e. slightly downwards. This is great for visibility.Some people say the plastic clip on the strap is prone to breaking, or that it's difficult to put on and take off. At first, yes, it's a bit tricky because the clip is separate and it's small so you might drop it. But, once it's in one side of the 'rungs' of the ladder-like strap, position the light on the post, pull the other side of the strap around the post and slot it into a rung. You can pull very hard on the rubber - it's pretty thick but also stretchy. It takes about 15 seconds! Also, the clip has never broken, even when the rubber is very tense.The only possible issue is that the plastic clip will touch part of the seat post, hence if your post's paint is thin, it may cause a mark. You can simply put some gaffer tape on the flat bits of the small clip. I haven't - and I've noticed no marks on my seat post. Not worth the trouble for me.I recently ordered another M2 in December 2020, for a recently acquired second bike. Highly recommended as a rear bike light - in fact, don't bother browsing other ones, just buy this one now!

Quality build. Easy to setup and use. Really bright light and has multiple flashing / still options. Charges via USB.Will review once fully used on a cycle .See my video on how to set it up .It could be a 5 star rating but I havent taken it out on the road yet so will review again once I have.

Bought this light as it was on special offer as another backup light. As I often cycle and walk on unlit narrow rural roads I am always keen to ensure I am seen in plenty of time. Having only bought it as a secondary light I was quite surprised at the brightness, I was further impressed by the build quality. All the castings and moldings are nicely finished and the whole light has a solid quality feel. The output is very bright and visible even in direct sunshine, I hope it lives up to the projected output times as I will now be using it as a daylight running light as well. When the light is charging the centre lettering flashes red and turns solid green when charged, which I thought was a nice touch. Overall very happy with my purchase

It’s a cool little light with lots of modes (that you don't really need and could even be distracting to drivers) and easy to install and charge however not worth fifteen pounds. You can buy decent front and rear sets for less. Eight or nine would be more appropriate as I don’t think it cuts it as a main rear if you cycle regularly after dark.
