WSDCAM USB Rechargeable Bike Alarm with Remote, 110dB Loud Wireless Anti Theft Vibration Motion Sensor Vehicle Security Alarm System Waterproof Bicycle Trailer Motorcycle Alarm

This is a great product. It’s the second one that I’ve bought.

Remote is a little sensitive but overall it’s great

I originally purchased this, because I really didn't "need" a taillight. However, I don't have enough stem space below my seat to mount this there, and there isn't much room under the seat; I didn't feel confident with this. I also didn't feel comfortable knowing whether it was fully charged or not, as there is no indicator. I returned this and purchased the WSDCAM Remote Bike Tail Light with Alarm, Smart Bike Brake Light, Auto ON/Off, Long Battery Life Rechargeable Bike Back Light, 110dB Loud Antitheft Alarm, Waterproof Rear Bike Light Bicycle Tail Light. This one comes with a fastener to attach it to the rails under the seat AND when charging the red "taillight" is illuminated - and goes off when fully charged. Happy with my upgrade!

I have charged it up and mounted about a month ago. I haven't used it a ton but it seems to work great still. I'm pleasantly surprised because it was quite cold for several days in the middle with no use so I expected the battery to be low or dead but it's still doing great. I definitely recommend in addition to traditional locks. The alarm gets a lot of attention and even locking it makes people reconsider messing with it at all. I have only had a couple of times where the alarm told me someone tried something when I was out of earshot. Only a single cable lock was ever missing once but the inexpensive item it was securing was still on my bike, so I believe the alarm scared them off just as they snapped the cheapest lock.

Excelente producto, tal cual la descripción.Muy feliz con mi compra, muchas gracias.

I was surprised how loud the alarm was. It sounds like the old car alarm with all the sirens and noisy sounds. My wife and I were riding on the towpath trail, see I retired last year so I got time to write a long review. Anyway, they have beautiful restaurants and sports bars on the trail and you can just pull your bike up to the many handsome bike racks and step inside to purchase a refreshing adult beverage of your choice. My young 50 something year old stunning wife, said “ Honey, I’m worried about the bikes! I said” Never fear, your big strong protector, who would die for you, is here. She said” Batman is that you? I said No, it’s Honey, and I’ll go check on the bikes. So I ran fast to check on the bikes, so I can get back. I hear out the corner of me ear, my bike alarm was going off, here I come electric bicycle. Just as I arrive, a little old lady sitting on the picnic table looking like her name was Ladybug, with both hands over her ears looking at me screaming” turn this thing off, so I said, that’s what you get for messing with my bike. She said, someone bike was parked next to your bike and unlocked their bike, and I said’ and messed with my bike. She said no, it was next to your bike, I said I don’t believe you, she said, no really. I said, lady if you touch my bike one more time, I’m going to dig my hand down in my pocket and give you all these hundred dollar bills. Have a good day

This thing actually works really well. The controller is good the sensitivity and everything was perfect right out of the box. Better than expected at this price point. Definitely deter someone from messing with your bike long enough to defeat the lock.

I purchased this alarm to go on my Honda side-by-side. Since I have to park it outside at this time, I wanted something to alert me if anyone tried to mess with it. The alarm is very loud. I am sure I could hear it in the house if it was triggered. It has not gone off due to wind or from the leaf blower. However, I opened a door one day, forgetting to turn it off, and the alarm sounded. I like this alarm. It does what I wanted. I gave it 4 stars instead of 5 because I would have liked a 2nd remote.
