10 Best Motorcycle Alarms 2026 in the United States

The ABUS Granit Detecto XPlus 8077 2.0 is a sturdy motorcycle lock that combines physical security with an intelligent alarm system. Its hardened steel construction, including a 13.5 mm thick locking bolt and solid housing, offers strong protection against tampering or theft attempts. The alarm features a clever two-stage system: it first triggers a gentle pre-alarm when movement is detected, warning off potential thieves early, and if movement continues, it escalates to a loud 100 dB alarm lasting 15 seconds. This sound level is effective at drawing attention without being overwhelming.

A standout feature is the transport mode, which uses 3D position detection to allow the bike to be moved slightly (e.g., during transport) without setting off the alarm. LEDs clearly indicate the lock’s status and battery life, simplifying use and maintenance. Installation is straightforward as it fits onto the brake disc, typical for this type of lock, making it user-friendly. However, it lacks smart home or app connectivity, so remote alerts or control are not available.

This lock suits riders who need a reliable alarmed brake disc lock offering strong physical security combined with a smart alarm warning system, especially if they prefer a simple, robust device without additional tech features.

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.

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 includes a warning beep that activates with light touches to warn potential thieves before the full alarm sounds, providing balanced sensitivity to avoid false alarms while still offering protection.

The CR2 lithium battery powers the alarm and is designed for long life. Installation is straightforward as it functions like a typical disc lock that fits onto your motorcycle’s brake disc. Included accessories such as keys, an Allen wrench, and a carrying pouch add convenience for the user.
