Best Powersports Alarms & Anti-Theft of 2025

"I feel much better using this lock than my previous securement method. It's hefty, solid, and secure. The audible alarm is a bonus, although I was unable to trigger it. I'm mainly focused on the locking mechanism, and it satisfies my needs."

"So far, I'm impressed! This lock is loud and easy to install on my Suzuki. I love how quickly I can set it up day to day!"

"I bought this lock a few months ago for my motorcycle. Unfortunately, it wouldn't open after I used it. I had to call a locksmith to get it off, and it took over three hours. I contacted Kryptonite, but their customer service was slow to respond. They did eventually offer to replace the lock, but I'm still hesitant because of my previous experience."

"I found the Kryptonite Disc Lock to be incredibly strong and durable, giving me a great sense of security. It's also lightweight and the strap feels comfortable to handle. The design is clean and elegant, making it easy to open and lock up. I just spray some WD-40 if the key ever sticks. Overall, it's a solid, reliable choice!"

"After my motorcycle was targeted for theft, I can confidently say that this lock did its job. The thief tried everything to remove it, but it held up. I was relieved when a neighbor scared them off. I'm really glad I bought this name brand lock; it's worth every cent. My only minor complaint is about the rubber cap for the keyhole not fitting perfectly. Regardless, I recommend it to all riders!"

"This lock is a fantastic find! It's reasonably priced without sacrificing quality. It performs just as well as more expensive options, and the attention to detail is impressive. For anyone looking for something that is reliable and well-made, this is the ideal choice. I highly recommend it!"

"This product is easy to use and works well. It arrived quickly and was well packed."

"I absolutely love my alarm lock! It's affordable, has a hefty build, and the loud alarm is perfect for scaring away potential thieves before they get the chance to damage my bike. I highly recommend you buy one before the price increases!"

"After experiencing theft with my electric scooters, I decided to step up my security with this lock. It's great because it's much harder for thieves to cut through compared to traditional locks. The alarm is incredibly effective—it emits a loud warning chirp with the first jostle, escalating to a full alarm on the second. While it won’t stop all determined thieves, I’ve gone a while without another theft, and I credit this lock for that!"

"I recently attached this to my Terratrike's front disk, and the slightest movement sets off the alarm. It’s incredibly loud and ear-piercing after the warning alert, but it effectively stops one wheel from turning. It's easy to carry in my bike bag, and I'm planning to buy more for my other bikes!"

"This lock works perfectly! It's loud but not too sensitive, so loud stereos don’t trigger it. I appreciate the bright colors that help deter potential thieves. Installation was a breeze, and overall, it’s a great value."

"This lock has a nice design and is fairly lightweight, making it easy to carry in my backpack. The audio alarm is superb—loud and sensitive enough to screech out a warning if the bike is merely touched. However, I found it a bit too sensitive; even dropping a box 12 feet away triggered a beep. Still, it's definitely worth upgrading from cheaper locks."

"I’m hoping this will give my husband peace of mind when he travels on his bike."

"I bought this out of curiosity. It seems to work well as a deterrent; if thieves want your bike, they'll get it. At my local bike shop, they wanted $80 for the same thing… I would definitely recommend it."

"When I locked it and gave it a slight shake, it started screaming. I have to say, it's very loud and sensitive, so always keep your key with you!"

"The seller contacted me right away and issued a full refund. I must have just received a slightly defective product. Despite that, the lock works well. I appreciate businesses that prioritize their customers, so I'm raising my rating to 5 stars. I suggest purchasing from them, as they will take care of you if issues arise."

"I've been using this lock for an entire riding season, and I've had no battery issues. It's compact yet heavy, and the sensitivity can be a bit much. I often use it as a theft alert rather than a deterrent. The alarm is piercingly loud, and I've learned to position it to avoid false alarms from rain. Overall, it’s perfect for my needs!"

"So far, I find this lock to be a solid product. It works as intended and is quite sensitive to movement, but I appreciate that it gives a warning before fully activating. It’s a good deterrent for safe areas, but I wouldn't depend on it in a high-risk location."

"I was pleasantly surprised by how easy it was to attach to my front brake disc. It works perfectly and is incredibly loud. The fail-safe cord is a nice touch, reminding me it's there. I highly recommend this product for added security."

"After receiving this the next day, I found it to be a great theft deterrent. The lock is strong and the alarm is annoying enough to scare off amateur thieves. With my Harley Road Glide locked up, I feel more at ease knowing they would have a tough time trying to roll it away."

"The sensitivity of the alarm can be a bit much, especially on a windy day when the bike is covered. It does draw attention with its high-pitched sound, which is a good deterrent, but it can be a nuisance too."

"I put this on my scooter and I'm really pleased with how it works. The sensitivity is perfect, alerting me with a warning beep when I cover it with a tarp, and it triggers a loud alarm if anyone tries to move it. It's small, lightweight, and super easy to attach. I even loved the funny advertisement!"

"I purchased these alarms for my overseas trip and they were fantastic! I programmed two for one remote and used one on the door. They're incredibly loud, which was a pleasant surprise. I even found an unexpected use for them at home to keep my dog from getting into the blinds. I can adjust sensitivity, but I didn't even need to. If you need a reliable motion alarm, this is a great choice!"

"I recently added this alarm to my electric scooter and it has been a game changer. The loud sound ensures that any tampering will alert me immediately. Installation was quick and straightforward, taking less than 10 minutes. Plus, the remote control is so convenient, allowing me to activate or deactivate the alarm from a distance. It’s become an essential part of my scooter setup!"

"I've had this on my bike for a few months, and it works every time I try to take it off!"

"I purchased this for my Honda African Twin for road trips. After reading the reviews, I went with this one. Shipping was prompt, and after charging it up, I easily installed it on my bike. It works as advertised, loud enough to get attention, and I appreciate the key feature for easy disarming and removal. Great size for traveling and impressive battery life make it a fantastic value!"

"I got this lock and have used it a couple of times. I found that I could lock up more than one bike using the same lock by running the cable through another fork. The alarm is incredibly loud, making it hard to move a motorcycle while it's locked. The mechanism seems secure, and for the price, this system is unbeatable!"

"I've been using this lock for a few weeks now to protect my motorcycle in a shared parking lot. It's my first lock and very easy to use. I can lock it on the rotor in seconds, and the reminder cable adds extra peace of mind. The chirp when it's locked is a nice touch, letting me know the alarm is armed. The package includes everything needed, including batteries and a carry pouch, which is great for storing it while riding. The lock feels solid, and the flat keys are a great feature. I’d definitely recommend this product!"

"I've used this lock every day after riding, and it's a solid lock that does its job."

"I thought I'd have a glowing review since it's cheap and comes with extra batteries. However, it can lock itself when I hit bumps. It's frustrating, especially since I often forget my keys. They should make it harder to activate. Otherwise, it's a great product and worth the money."
