10 Best Motorcycle Alarms 2026 in the United States

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.

The ABUS Granit Detecto XPlus 8077 2.0 is a sturdy motorcycle alarm lock made from hardened steel, designed to provide strong physical protection by securing your bike's brake disc. It features an intelligent two-stage alarm system with a pre-alarm warning that triggers on initial movement, followed by a 100 dB loud alarm if the movement continues for 15 seconds. This helps deter theft early without immediately causing noise, which is a thoughtful touch. The lock’s XPlus cylinder adds extra resistance against tampering, like picking, making it harder for thieves to defeat.

The lock includes LED indicators that show the alarm status and battery life, helpful for knowing when maintenance is needed. It runs on two AAA batteries, which are included. Transport mode lets you lock the bike without triggering the alarm, useful if you need to move the bike short distances without causing false alarms. Installation is straightforward since it fits directly onto the brake disc, requiring no complex setup. While the lock is robust, water resistance is not explicitly stated, so caution may be advisable in very wet conditions.

This product suits riders looking for a reliable physical lock combined with an audible alarm, especially those who want a smart alert system before the full alarm sounds. It may be less ideal if digital or remote alarms are preferred or if waterproof features are required. The lock balances tough mechanical security with a helpful alarm, making it a solid choice for everyday motorcycle protection.

The lock is constructed from forged stainless steel, making it crash-resistant and durable. Its waterproof design ensures resistance to rain and rust, making it suitable for outdoor use.

Installation is straightforward with its one-press locking system, and it fits disc brakes up to 6mm thick, which covers many common bikes and scooters. The inclusion of a 5-foot reminder cable helps reduce accidental riding with the lock still engaged, enhancing safety. It operates on 12 LR44 batteries, with backups included, providing good battery life without frequent replacements. While it does not feature remote control operation, all functions are manual.

The lock requires disc brakes to fall within specific size limits (thickness and width), so checking compatibility before purchase is important. The set also includes two keys and a carry pouch for convenient storage and transport. This YOHOOLYO alarm disc lock serves as a reliable, easy-to-use security tool for riders looking for a loud, physical deterrent with weather resistance, though it lacks remote operation and has certain size restrictions that buyers should verify.
