Here’s an overview of the Best Motorcycle Locks that we’ll explore today:
Motorcycle locks sit at the critical edge of deterrence and accessibility. A well-chosen lock can dramatically increase the time and effort a thief must invest, often making other security layers more appealing to would-be thieves. In this comparison, I evaluate five popular disc/Pin-tumbler style alarm locks from RUBY.Q, YBLNTEK, and Kryptonite, spanning a price spectrum from budget to premium. My evaluation focuses on construction quality, alarm effectiveness, ease of use, battery life, weather resilience, and real-world usability when attached to common rotor/hub configurations. The methodology combines factory specification parsing with practical field insights: how the lock behaves when installed on typical disc brakes (up to 6mm or 6.5mm pins), the reliability of the alarm in routine vibration scenarios, and the practicality of maintenance (batteries, USB-C charging, and reminder cables). The lineup includes a budget multi-pack option, a fingerprint-enabled unit, an integrated alarm heavy-duty model, and two Kryptonite offerings that balance compactness with reliable alarm features.
1. YOHOOLYO Alarm Disc Lock Motorcycle Disc Brake Lock Anti-Theft Waterproof 110 dB 7mm Pin 5ft Reminder Cable for Motorcycles Bike Scooter Carry Pouch (Black)
- Brand: YOHOOLYO
- Manufacturer: YOHOOLYO
Overview: The YOHOOLYO lock is a metal-bodied disc lock with an integrated 110 dB alarm, a 7 mm locking pin, and a 360-degree adjustable mounting capability. It ships with a reminder cable, carry pouch, and six internal batteries with backups, suggesting a heavy emphasis on longish field life and ready storage. The design emphasizes weather resistance and a robust alarm system, making it a straightforward option for riders who want a simple single-lock setup with audible deterrence and a sub-$30 price point.
Performance-wise, the 7 mm pin provides decent resistance to casual prying and wheel-rotation attacks, while the 110 dB alarm offers a clear, attention-grabbing signal in parking scenarios. The product notes rust resistance and weatherproofing, which is valuable for riders who park outdoors. The inclusion of two keys per lock and a secure carry pouch improves daily usability, though the lack of fingerprint or modern biometric access means you rely on keys and the mechanical interaction. In practice, this lock excels as a secondary deterrent for everyday riders and can be effectively paired with a secondary lock for long-term security.
Pros
- Budget-friendly dual-pack option with 2 locks and accessories
- 110 dB alarm is loud enough to deter passers-by and alert nearby people
- 7 mm pin offers solid mid-range security for disc brakes
- Waterproof, rust-resistant construction with weather resilience
- Includes reminder cable, keys, and carrying pouch for convenience
Cons
- No biometric or keyless entry; relies on keys
- Alarm duration and sensitivity not adjustable in the listing
- Not rated for high-security, long-term anti-theft against determined thieves
2. Kryptonite Alarm Disc
- Brand: Kryptonite
- Manufacturer: Kryptonite
Overview: Kryptonite’s Alarm Disc Lock is positioned as a premium mid-range option with a 120 dB alarm, a 6 mm hardened steel pin, and weather-protected electronics. The zinc die-cast body is designed for durability in varied weather, and the product emphasizes offline reliability with replaceable batteries (CR2) that are rated to last up to a year. The unit’s weight is listed as 4.2 ounces, suggesting a compact form factor that can be carried easily without fatigue.
In practice, the 120 dB alarm is notably louder than many competitors, which can create a stronger deterrent effect in noisy environments or crowded lots. The 6 mm pin diameter and rotor-fit up to 6.5 mm offer compatibility with most common rotor designs, while the weather-resistant electronics module enhances durability in rain or spray. The battery life claim (up to a year) depends on usage but indicates a focus on low-maintenance operation. This lock is best for riders who want a robust, respected brand with strong audible deterrence and reliable operation across varied weather conditions.
Pros
- Loud 120 dB alarm for strong deterrence
- 6 mm hardened steel pin and rotor compatibility up to 6.5 mm
- Weather-resistant electronics and zinc die-cast body
- Replaceable batteries with up to 1-year life
- Compact, portable design suitable for scooters and motorcycles
Cons
- Higher price relative to some peers
- No fingerprint or keyless entry; still relies on keys
- Some users may want dual-lock solutions for higher security banding
3. YBLNTEK Motorcycle Disc Brake Lock with Alarm 120dB
- Brand: YBLNTEK
- Manufacturer: YBLNTEK
Overview: YBLNTEK’s offering stands out with a fingerprint unlocking mode alongside traditional keys, a 7 mm pin, and a 120 dB alarm. It uses USB-C rechargeable power with a stated life of up to two months of regular use or up to six months in standby, and it ships with a reminder cable and two keys. The aluminum body with rubberized coating is designed for anti-drill protection and weather resistance, while the fingerprint feature aims to reduce the friction of carrying and using keys.
Performance-wise, the fingerprint unlock claims a 99% recognition rate and 0.2-second unlock time, which is competitive for a lock of this type. The combination of an alarm, anti-drill properties, and USB-C charging makes it a compelling option for riders who want higher convenience and faster access under adverse conditions. However, biometric reliability can vary with sweat, dirt, or capricious sensor performance in real-world weather, so it’s prudent to keep the backup key as a reliable fallback. Overall, this unit is best for riders who value convenience and modern access methods, and who are okay with charging routines.
Pros
- Fingerprint unlock provides quick, keyless access
- 120 dB alarm with vibration sensitivity and anti-shock sensing
- USB-C fast charging with long standby
- Anti-drill aluminum body with weather resistance
- Includes reminder cable and 2 keys
Cons
- Biometric systems can be less reliable in rain or sweat
- Higher price compared to purely mechanical locks
- USB-C port requires care to maintain waterproof seal
4. Alarm Disc Lock Set
- Brand: RUBY.Q
- Manufacturer: RUBY.Q
Overview: RUBY.Q’s budget-oriented alarm disc lock set includes two locks, each with a 7 mm pin and 110 dB alarm, plus a reminder cable and carrying pouch. The package emphasizes value-per-lock and convenience, featuring two sets of security hardware with six batteries per unit and backup options. This offering is a practical solution for riders who want a multi-lock approach within a tight budget and appreciate the added security of a reminder cable for parking deterrence.
In use, the set provides straightforward, push-button activation and a focused deterrent with audible alarms once vibration is sensed. The dual-lock approach can complicate theft attempts by requiring more devices to bypass. The rugged alloy steel construction and weatherproofing help ensure reliability in rain or shine. On the downside, the lack of advanced access methods or Bluetooth/fingerprint means it remains a conventional, mechanical deterrent, which may be less appealing to tech-oriented riders seeking convenience.
Pros
- Excellent value for a 2-pack with accessories
- 110 dB alarm widely audible in outdoor parking
- Two locks increase coverage and deterrence
- Waterproof and rust-resistant construction
- Includes reminder cables and storage pouch
Cons
- No biometric or advanced access options
- Requires physical keys for operation
- Bulkier to carry compared to single compact locks
5. Kryptonite 000884 Keeper 5s Yellow Disc Lock
- Brand: Kryptonite
- Manufacturer: Kryptonite
Overview: Kryptonite Keeper 5s is a compact disc lock with a 5.5 mm pin diameter, designed for smaller rotor holes and easy handling. It uses a staple-style disc mechanism and includes a reminder cable. The yellow color helps visibility, and the unit dimensions suggest a lightweight, highly portable form factor ideal for quick stops and scooters where space is at a premium.
Performance-wise, the Keeper 5s emphasizes compactness and low weight while providing reliable mechanical locking. The 5.5 mm pin is at the smaller end of the spectrum, meaning it’s best suited for riders who prioritize portability and park in low-risk areas or pair it with other deterrents in higher-risk environments. The product’s long-standing Kryptonite branding signals a track record for compatibility and serviceability, though the smaller pin may be easier to defeat by determined attackers compared to heavier pins. The included reminder cable adds a practical deterrent for misplacement and move-away prevention.
Pros
- Very compact and lightweight for easy carry
- 5.5 mm pin suits smaller rotor holes and scooters
- Remindercable included for deterrence and reminders
- Distinctive yellow color improves visibility
- Reputable Kryptonite brand with reliable support
Cons
- Smaller pin diameter offers less resistance to brute force
- Limited rotor compatibility compared to 6 mm pins
- Not ideal for high-risk, high-threat environments without additional measures
