PADONOW Alarm Bike Tail Light: Wireless Remote Bicycle Rear Light USB-C Rechargeable Smart Motion Anti Theft Taillight with Loud Horn Red Led Flashing Lights Waterproof High Lumen Cycling Back Light

Easy to install, quick disconnect for USB-C charging works great, alarm is very loud, bike bell gets my attention on the road, backlight has multiple modes and is visible from far away. Remote de- and attaches to the handlebar mount easy, button layout is acceptable. Probably a good idea to have the buttons color coded for easier identification, but this is rather minor compared to the features for this price point. Good purchase for me, recommended.

I like the choices to light up, just wish there was more lit area.

Instalation was a breeze and alarm works just fine and nice n loud!! You can barely touch the bike after alarm is set and it will Chirp! And a second touch will sound the loud alarm ⏰️

Worth adding this item to your ebike, bicycle or scooter if you need to ward off thieves. I live in a densely populated city and ive had 3 bicycles stolen in my lifetime and off my property. I guarantee this will work. This product is sensitive to movement and is shatteringly loud. This thing is louder than my fire alarm. I tested it out as soon as I opened it and it gave me a real jump scare. I guarantee no one will even leave with your transport. I already recommended it to all my friends with bikes.

It will scare and annoy the bejeebus out of any potential thief. Hopefully they will scram rather than having to listen to it for even a moment longer than they have to.When you're setting it up, I recommend that you wear earplugs, or do it outdoors. And I recommend that you turn the "horn volume" down to minimum. This is also the volume of the chime it makes when you turn the alarm on or off. It's simply too loud on its default setting.I like that it's combined with a tail light.I'm about to buy a second for my second bike.UPDATE: "horn volume" also determines alarm volume. So you should keep it at max.
