Auto-Sensing Rear Light G4R, USB Rechargeable, 240HRs, Precise Brake Sensing for Cargo Rack, Large Reflector, 50/80mm Screw Mounted, Easy Release, Made in Taiwan

The media could not be loaded. If you have an ebike with rack in the back this light might be for you. Man the mount and unmount of this light is perfect. I have purchased quite a few lights and they fail on so many levels where this rear light is really Best in slot for me and my bike.The mount is easy to install. Others were a nightmare.The Mount is sturdy and the detaching of your light is easy so you can recharge it. The light is nice and bright and lasts quite a long time.I cant say how happy I am to finally find a light that dosent fall off, break when it rains or made with cheap mounts. I have lost many lights due to cheep products. Like the rubber latch with a Mediocre plastic hook or complex mounts.This one attaches to the back of my rack with screw and detaching it is a breeze. I purchased it March 1st and is now March 22. Rain, freezing cold and bumpy rides every day from home to work and back, this light hangs in there and dosent disappoint. Great job in creating a good product.

The bike light charges quickly via the USB and offers high visibility. It is a "smart" light as it senses stops and remains on, indicating a braking event. It is easy to remove from my bike to charge and snaps back in. I've rode in heavy rain and the light had no issues.

Lights are great. Most people get upset when they get the lights but now how do you mount them. My solution-simple cable clamps that you can get at any auto or hardware store-cost pennies. These will fit over your rear rack tube and tighten down where they won't turn or move. You can get various size clamps to fit different tube sizes.

I ordered this light because my eBike came without an integrated tail light. To my satisfaction, this light performs exactly as advertised. It has held charge for a few weeks so far without needing recharged and all of its modes work fine. The various settings are nice and bright, and the light reflects passively if it's not on. In terms of standing daylight lights, I find the blinking ones to be best, but usually opt for solid lights in the night.If it weren't for the mounting nuts, however, this product would be an indisputably great purchase. The two little bolts they give you to screw the light on to your rack are poorly manufactured - one of them fell off during one of my first commuting rides, never to be seen again. I had to not only Jerry-rig some duct tape and hair ties to keep the light in place, but also twist on a few aftermarket nuts to keep the light from literally falling off my bike. The nuts I put on there have what I think is a circle of nylon inside them to keep the screw from getting loose (which works VERY well, I need a pair of pliers to get them off because can't twist them off with my hands) and they keep the light in place for me.Other than that, the light is incredibly useful.TLDR: Great rear rack light, terrible manufacturer mounts.

Works great. I feel as safe as can be when riding on a busy highway. I little overpriced but how valuable is your life. Does come on when there is movement and does go off when the bike is not moved. Not sure how long a charge will last as of now. Easy to install. Bolted right to my rear rack on my Rad Ebike.

Fantastic product! Battery lasts forever, nice and bright, cannot live without the auto-on. Bought two!

not sturdy enough for any but the smoothest of rides. I only had this for a couple of weeks and when I hit a bump the clip that holds the light on its mount sheared through and the power button broke off when the light hit the ground. It is now broken and useless.

I have four of these and have had them for one year. The light is bright and I like the 4 modes and the auto turn off feature. The battery life is good as well (in slow blinking mode). However, the manufacturer's claim of IPX6 is not credible. 'IP' is Ingress Protection. The first digit is the rating for solid particle protection and the second digit (in this case '6') is for liquid protection. '6' indicates "Water projected in powerful jets (12.5 mm (0.49 in) nozzle) against the enclosure from any direction shall have no harmful effects." A couple of the lights I have are no longer functional because I got them wet washing the bikes. With the listed IP rating I thought they would survive. I realize they are not listed as waterproof though. This taillight is expensive. It is easy enough to remove from its bracket when washing your bike. Overall, I still like this taillight but am disappointed with its water resistance.
