Proton R60 Smart Bike Tail Light Motion Sensing Rear Bicycle Brake Lights Auto On/Off Taillight USB Rechargeable Fit's All Bikes Aero Road Bike Mountain Bike BMX

My original R60 died pretty quickly, it seems it was pretty defective to begin with. Night Provision jumped, made sure I got a replacement quickly and I'm up and running again. Time will tell if this works better than the first, and I'm crossing my fingers hoping for the best. Will update here if the situation changes.Update, original review:Battery doesn't last very long, no warning when it runs out.I manage something less than 5 hours of riding time with this light on blinky mode, it's not enough for a week's worth of commuting: the ideal situation, then I would just charge it once every weekend. When it runs out, it just turns off without warning, it doesn't step down to a lower lumen level. I want to like this light as the feature set is nice, but the short battery life is very offputting.

I didn't have a ride partner to verify it was working in the fashion it was designed but I could see the brightness in the reflection of the windows and parked cars. I'm going to use my Blitz light in conjunction with the braking light.

This is a short term review after 20 plus miles ride.Pros: easy to install to seat post. The blinking pattern has some randomness to it which I am sure make you and bike noticeable in traffic. The brake light function works well even at walking speed, when you slow down or stop it turns on immediately. Thus, the highest brightness is very bight, almost as bright as car's brake lights.Con: no other mounting method provided.Conclusion: a must have for bicyclists.Update: after months of using I still like it very much. Batteries last a long time, I went on two days trip with 4 hours ride each day without charging and the light was till brightly flash at the end. The water proofing is good, no problem with sprays. The rubber mounting has held up so far.

Light worked great, super bright, durable, brake system worked well. But the mounting system is absolutely awful, due to the clip system with the rubber having too short of a slot. I was always worried that it would fall off, and it must have, because I came home and it was gone. I would purchase again if the mounting system were different, but I will probably have to go to a competitor for now.

I was a little skeptical about getting this tail light because I was not how accurate the stop sensor would be. I was pleasantly surprised at how bright it is and how accurate the stop sensor is. I ride mainly during the day but I like having the flashing light to warn cars behind me. The stoplight's even better because it turns solid when it senses the braking. I even looked a few times to make sure it was working, and even after coming to a full stop, when I looked the light was still solid red when I got off the bike.I have not used it for long but so far, it's working great!

Tail light worked on the first trial (the day we received it). Charges fine, illuminated very well when braking, but the second time we tried to charge it the light stays on and the light won't even turn on. This is the main reason we're returning it besides for its rubber band that wont stay on the seat post.

The motion sensor is great. Several minutes after stopping it turns off automatically, so it doesn't waste battery. Next time I ride it starts blinking again without me turning it on. When I stop it switches from flashing to solid red. It's bright. The charge lasts for (easily) weeks of moderate riding (50 miles / week). To recharge I put a mini-usb charger I already owned on an extension cord in the garage and recharge without taking it off the bike. That way I don't have to dismount it to recharge. I highly recommend this light.

I like l have bought 2 other brake lights but l can see that this light is very visible. Alot brighter then the other two. Also,l like that is simple. Just a brake light that goes on when you brake. I like that and that it is easy to charge l ride an electric 1,500 watt bicycle and I always wanted brake lights. One of the other brake lights has turn signals and l very seldom use them. A little more pricey then the others but l like the brightness of this one.
