🚴 BikeSpark G2-20lm Auto-Sensing Rear Light - Super Bright LED Bike Tail Light with Motion Sensing Deceleration Flash - USB Rechargeable - Water Resistant IPX5 - Made in Taiwan Review

Awesome bike taillight that reacts to movement and turns on and off without you having to worry about leaving it on. Rechargeable so no need to put batteries in. The lighting options are great, ranging from constant to flashing, catching the attention of motorists from a neighborhood away. Very easy to install and charge, essential light for day and night cycling. I will buy for relatives as a gift

I read several reviews that the light fails. There are no correct installation instructions, so I looked closely at the nozzle and saw that they are really two hooks from the same locking mechanism. After securing it around the seatpost, look closely and you'll see another hook (the back of the S hook is sticking out). Hook the last loop with it, and now it will be secured with two hooks. I hope it will be much safer.

Easy to assemble and has some flash patterns. The reason for my rating is that the on/off button that changes the flashing pattern has a design/handling issue that I believe is almost fatal. It's made of very soft rubber and doesn't fit properly in a coupe. It slides out of position very easily with very little pressure. I wonder how he'll behave on a bumpy bike ride. I attached a piece of tape to make sure it didn't fall off.

The auto on/off feature caught my attention, I found it interesting and decided to try it. Before using this light, I quite often forgot to turn off the light on my bike. I kept my flashlight charged the whole time. I tried the light last weekend, it was nice not having to worry about forgetting to turn it off. This light is very bright, which is perfect for us cyclists who ride our bikes early in the morning. So far, so good. I'm happy with it! I get another gift for my husband for the new…

Really good brake light, I particularly liked the automatic on/off and the light pattern that changed as I slowed down. The only reason I'm not giving it 5 stars is because the mount is terrible. There's nothing quite like going on a long journey and realizing halfway through that your taillight is gone. The elastic was still wrapped around my seatpost, but the attachment system was completely gone. I am happy to report that I have contacted the seller to express my disappointment with the…

I would say I forget to turn on my tail light about 80% of the time when I'm riding my bike. I also often forget to turn it off until I get home. This product solves both problems. Came in nice packaging and looks good. I checked the brake lights manually and they seem to work fine with little movement as described. I am currently giving this 4 stars for two reasons. 1. There were no instructions. Sure, it's pretty easy to work with, but a little mini-page or two with instructions would be…
