10 Best Motorcycle Alarms 2025 in the United States

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 Monimoto 9 Anti-Theft GPS and Alarm Tracker stands out for its easy DIY installation, making it a user-friendly option for motorcycle owners who might not be comfortable with wiring. This device ensures you can move it between vehicles without hassle. It excels in sensitivity by providing instant alerts via phone calls if any unauthorized movement is detected, which can be more effective than traditional push notifications or SMS messages.

The Monimoto 9 offers global coverage through an international e-SIM, but it's important to note that a $49 annual fee applies after a two-month free trial. This might be a consideration for budget-conscious users. In terms of durability, the tracker is rugged and waterproof with an IP68 rating, ensuring it can withstand harsh environments. The battery life is solid, featuring a USB-C rechargeable battery that should minimize the need for frequent recharges. However, one potential drawback is that the tracker might require occasional charging, which could be slightly inconvenient compared to fully wired options.

The Monimoto 9 also boasts reliable customer support through its app, which adds a layer of ease for troubleshooting or setup assistance. While not explicitly featuring remote control, the phone call alerts serve a similar purpose by keeping you informed in real-time. This tracker is well-suited for motorcycle owners who prioritize ease of installation, sensitivity, and robust water resistance, although the annual subscription fee is a factor to consider.
