Featuring proven sensor technology, it emits warning beeps and a loud alarm upon unauthorized movement, automatically rearming after inactivity. Crafted from durable, waterproof materials, it withstands harsh weather and physical attacks. The package includes essential accessories like a reminder cable, spare batteries, keys, and a carry case, making it a comprehensive, easy-to-use security solution trusted by over 1,000 users. ## Description How to use: automatic locking, simply snap the lock into place, a beep will confirm that the lock is active. After 15 seconds, the alarm will be activated. If the alarm senses a blow or movement, then there will be a beep as a warning, if further movement is felt within 5 seconds, then the alarm will sound until the movement stops. If there are no further shocks after 35 seconds, the alarm automatically stops and reactivates itself. You can quickly unlock it with the key. Maintenance: Spray lubricant into the lock every 3 months to keep it in good condition. Review: Great alarm - Works really well. Fits the smaller disc holes that my other disc lock won't. It's bright and easily visible. Do buy a reminder cable as it doesn't include one. You get spare batteries (6 small cell batteries) and an alan key to open the battery hatch. To arm it you just line up a hole and push the key lock in. I recommend a squirt of WD40 before using to lubricant the pin and lock button. When it arms you get 5 seconds to get clear and you're good to go. If it's moved you get 3 loud beeps then the next movement sets off a loud continuous alarm. As for wind (people's usual concern).... It has only gone off in 3 beep warning mode once - in a "named" storm where the bins were blowing down the road and trees were falling over! The main alarm didn't trigger but it would me and the neighbours up...buuuuuuut... This was exceptionally violent weather! The bike cover was bashing against it. Since then we've have heavy rain and storms and it's been just fine. Some day it isn't sensitive enough but I can vouch that it is plenty sensitive. I know this because I set off myself having failed to install in one smooth go because I was unwell and lacking coordination LOL You set off the warning beeps by the very touch of the key in the lock so, yes, it works! The only downside is I wish the arming and unlocking beeps weren't as loud as the alarm...I always feel guilty taking it off at 6am ...beeeep! This does mean that people watching your bike from a distance know you're arming an alarm which I guess is a good thing really. Best location to fit when covered is tucked away just behind your rear brake (to avoid covers activating). Best location to fit uncovered is probably front disc with reminder cable on your bar end for visibility. Would have been nice to be flouro yellow instead of plain yellow. Maybe some reflective paint would be good to. Really good product... With the money! Review: Loud lock - Good quality product at a fair price. Loud enough to send any would be bike theif running. An excellent deterrent and easy to use/fit. ## Features - 【ANTI THEFT SECURITY】Disc lock alarm fits motorcycles, electric bicycles, bicycles and scooters with disc brakes. Features proven sensor technology. Once armed, should a thief try to remove the alarm or move your vehicle, the alarm beeps. Should it detect further motion within 5 seconds, the alarm emits a 110db sound to scare away and draw attention. The alarm will continue to sound until no movement is detected for 35 seconds. At that point, the alarm silences and rearms automatically. - 【EASY FITTING】The JDC disc lock alarm is easy to fit. You simply push the key barrel locking pin until you hear a click. You’ll then hear a beep. This tells you the lock is armed and ready. To remove the alarm, you simply unlock with the keys. - 【DURABLE & WATERPROOF】Made from high strength metal and durable materials that are completely waterproof and weatherproof with a self closing key barrel. This alarm has been designed to be highly resistant to all forms of attack including brute force, drilling, and attacking with tools. - 【IDEAL FOR DISC BRAKES】The alarm fits all vehicles with disc brakes up to 7mm thickness. This includes motorcycles, electric bicycles, bicycles and scooters with disc brakes. Fits 95% of motorcycles, please check the lock dimensions to make sure it will fit before purchasing. - 【ACCESSORIES】As well as a high grade alarm you’ll also receive a reminder coil cable, a carry case, 2x battery sets, 2x keys, and an allen key. Lubricate the lock key barrel every 3 months to keep it in good working order. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005GKAZB8 | | Batteries | 8 LR44 batteries required.

I could not find any other information, but I will follow closely this conversation n case I experience this problem in the future.. **Q: Would this fit a honda varadero 125 xl? Also, is this alarm system too sensitive?** A: Hi, Yes this should fit, it fits 95% of bikes, please check the dimensions on the listing just to be sure. The alarm has normal sensitivity and will activate if knocked or moved, thanks **Q: Can I use it without alarm? At busy areas will go off constantly when people moving their bikes and touchin it** A: No, once it's locked the alarm is set, wouldn't worry about the alarm going off as I found it very difficult to set mine off,short of hitting it with a sledgehammer! But then that is of course up until day 4 of using it, it stopped locking! I sent mine back and would never buy one again! Don't order this if you value your bike **Q: will it fit yamaha 125 ybr** A: I can't see why it wouldn't..it fits my kawasaki GTR 1400, not by putting the shackle through the vented disc holes, but by completely bridging the width of the disc itself. (I found this easier than fiddling around trying to locate the shackle with the holes.) I guess it will if you have discs with holes in, but if the disc is very broad and solid, then it may not. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great alarm *by J***R on 18 November 2023* Works really well.

Loud enough to send any would be bike theif running. An excellent deterrent and easy to use/fit. ### ⭐⭐⭐⭐⭐ Fantastic value, great product. *by K***N on 10 April 2014* I just bought a new motorcycle that is considerably more valuable than the last one, and so I wanted to step up my security. I already use a chain on the back wheel, so using this disc lock allows me to lock both wheels, and so far the bike has been safe, both garaged and publicly parked. It's a simple design and easy to use. It has taken me a little while to learn to put it on last, and take it off first, as I have set it off by mistake while loading and unloading the top box, and putting the chain on and off. It doesn't go off at every husk of wind, but it is reassuring to know that it will sense bigger knocks. The alarm is suitably loud, and when stood right next to it it's quite ear-splitting and irritating, as it should be. The beep on locking lets you know it's working. The colour is also a useful design feature as draws attention to the device. As I have only owned for a few weeks, I'm not sure how long the batteries last but I like that it comes with a spare battery and key for backup. Would recommend, and the price is fantastic value for such a great product. ## Frequently Bought Together - JDC Motorcycle Motorbike Disc Lock ALARM – JAWS - BEEWAY Bike Cover for 2 Bikes, 210T Nylon Waterproof Bicycle Cover Anti Dust Rain UV Protection for Mountain Bike/Road Bike with Lock-holes Storage Bag --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/47933241-motorcycle-motorbike-bicycle-electric-bike-scooter-disc-lock-security-waterproof](https://www.desertcart.us/products/47933241-motorcycle-motorbike-bicycle-electric-bike-scooter-disc-lock-security-waterproof) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-25*
