YOHOOLYO Alarm Disc Lock Motorcycle Disc Brake Lock Anti-Theft Waterproof 110 dB 7mm Pin 5ft Reminder Cable for Motorcycles Bike Scooter Carry Pouch (Black)

So far, it has been working excellent. This has been after 6 months of use. It's very sensitive, it has very well built in electronics. For some reason it comes with extra batteries, but there's already batteries inside. And the batteries are full strength. Easy to put on, easy to put off. I just wish that the orange cord, the reminder cord that you put on your brake handle or your throttle, would be a little bit longer. I have a Suzuki Boulevard C50 (a cruiser) and so the distance from the brake rotor to the right brake handle, is a little bit long, and it feels like I'm putting a lot of strain on the orange cord. It's just very tight (hoping it will never snap) so if they made this just 2 inches longer, that would solve the problem. That's my only input. Everything else is perfect

I bought two. They work great and are very loud. If you want to protect your bike(s) this is how to do it

This lock exudes a premium feel, with a satisfying weight that sets it apart from its cheap counterparts. Setting it up is a breeze; simply slide one end of the loop inside the lock and the other around the handgrip. The wire serves primarily as a visual indicator, to remind you that the lock is securely engaged. It’s crucial to refrain from moving your bike while the lock is in place to prevent any damage to your bike. The alarm’s loudness is designed to effectively deter any would-be thieves. While no system is guaranteed to safeguard your bike from theft, using this with a U-lock around your tire will significantly increase the difficulty of theft.

The YOHOOLYO Alarm Disc Lock is a popular, budget-friendly anti-theft device designed for motorcycles, scooters, and bicycles. It features a sturdy all-metal construction with a 7mm locking pin, a 110 dB motion-activated alarm, and a waterproof design suitable for various weather conditions. The lock comes with two keys, a 5-foot reminder cable, a carrying pouch, and 12 LR44 batteries (6 pre-installed and 6 spares), offering convenience and value. ​

Updated Review: The seller reached out to me immediately and provided a full refund to me for this item. I must have just happened to receive a product with the slight defect noted below. However, as I mentioned below, the lock itself still works well. I respect businesses that obsess over their customers and maintain integrity. Therefore, I am adding 2 stars back (5 stars). I would recommend purchasing this product from this business if you are on the fence since you’ll be taken care of if something goes wrong.Original Review: The lock itself works fine. I have not had any issues with unlocking or locking. However, the built in alarm started getting triggered randomly. I parked in an indoor garage with no exposure to wind/movement and no direct exposure to other elements such as rain. My 30 day return window elapsed, so I was forced to resort to removing the batteries to the alarm (it is very loud and I cannot risk disturbing my neighbors if it goes off while I am gone) and so I strictly started using this as a lock, which was disappointing. I was hoping to have the alarm functionality. The issue started occurring about 60 days after purchasing. I have owned this lock less than one year as of the date of this review. I deducted 2 stars for the alarm issue. If the manufacturer or seller reaches out to resolve the issue, I will update my review accordingly.

I love this product. It’s really cool. Plus I have ADHD and I’m liable to takeoff with the lock on the disk. The cable helps remind me not to do that. I can connect it to my throttle. It’s very sensitive gives a warning and then goes off up upon the 2nd movement sometimes it even goes off when it’s storming outside.

Nicely done📦📦 works well on my RESM 650, this includes extra batteries as well!

Okay lets talk, no this is not an AI review.First off the price point attracted me. I recieved it today and it is packaged very well. You get the lock, spare set of batteries (I do wish they were not button batteries but at least they give you a second set) a nylon pouch to hold everything, a coiled lanyard, two keys, an allen key to open area to replace batteries.By the weight you can tell this is not some cheap lock. The alarm is pretty piercing and loud. The throat is pretty deep so even if your rotor doesnt have cooling holes it still can reach the cutouts so it will lock onto the rotor.Am I happy with the purchase? YES, actually I will order a second one for my second ebike. (You cant be too carefull) SIZE: takes up the room of two packs of cigaretts. Definintely with the cost as long as batteries got a decent life on them.
