The alarm system is highly sensitive, featuring 3D position detection and an alarm that reaches at least 100dB, ensuring it will alert you to any tampering attempts. This lock is also equipped with an ABUS X Plus cylinder, which offers the highest protection against manipulation like picking.

The inclusion of two keys, an ABUS Code Card for additional or replacement keys, and a CR2 battery ensures you have everything needed for immediate use. The lock is made from steel and weighs about 2.64 lbs, making it sturdy but still manageable. The dimensions (11.81 x 7.87 x 7.87 inches) indicate it's relatively compact for its class. One of the standout features is its ease of installation; it’s user-friendly, so you won't need professional help to set it up. The lock is water-resistant, adding an extra layer of reliability in various weather conditions.

The remote control and Bluetooth connectivity features add modern convenience, allowing you to monitor and control the lock via an app. Customer reviews are generally positive, with a rating of 4.4 out of 5 stars from 147 ratings, indicating user satisfaction. This lock is ideal for those seeking high security and advanced features in a motorcycle alarm, but it might not be the top choice for budget-conscious buyers.

The YOHOOLYO Alarm Disc Lock is a solid anti-theft device for motorcycles, bikes, scooters, and similar vehicles. It stands out with a robust 110 dB alarm that activates upon vibration or shock, which can deter potential thieves effectively. Constructed from forged stainless steel, it promises durability and crash resistance, making it a reliable choice for daily use.

One of its notable features is its ease of use; with a simple one-press button operation, you can secure your vehicle quickly. It's also waterproof, ensuring it works well in rainy conditions without rusting. The lock comes with a 5ft reminder cable to prevent accidental attempts to ride off with the lock engaged, and it includes a carry pouch for convenient storage.

Additionally, it includes two sets of batteries (six internal and six backup), providing extended usage, and two security keys for added assurance. However, it lacks a remote control, which might be a downside for users seeking remote activation. The alarm’s sensitivity is a double-edged sword; while it ensures immediate response to theft attempts, it may also go off due to minor vibrations, potentially leading to false alarms. Its compact size (3 x 1 x 2 inches) and light weight (12.3 ounces) make it easy to carry and store.

The URBAN UR6 Hi-Tech Alarm Disc Lock offers robust security for motorcycles, scooters, and bicycles. One of its standout features is the alarm system, which can be turned on or off, and emits a loud 120dB noise to deter thieves. The A+ sensitivity ensures it is highly responsive, and the warning function with light alert adds an extra layer of protection by providing an early alert before the alarm fully activates.

Additionally, it is compatible with various types of vehicles due to its 6mm locking pin, though users with larger brake disc holes might need a different model like the UR10 with a 10mm pin. The replaceable electronic module and long-lasting CR2 battery, which can last up to 2-3 years and is unaffected by cold weather, add to its convenience. Installation is simple, allowing for one-handed locking without a key. It is also fully waterproof, making it reliable in all weather conditions.

It does not come with a remote control, which could be a drawback for some users. Additionally, while it is practical, the need for optional brackets (not included) for carrying it safely when locked might be an inconvenience. However, its strong performance, ease of installation, and high level of security make it a great choice for those looking to protect their two-wheelers. The product is backed by a reputable European manufacturer, URBAN, known for high-security locks, and offers a 2-year warranty for peace of mind.
