Smart Disc Lock Review
eLinkSmart 100 Fingerprint Padlock
ADVANTAGES
LIMITATIONS
This heavy-duty smart disc lock redefines access control with its fingerprint recognition, remote authorization, and rugged build tailored for trucks, gates, and outdoor storage. With a 0.8 cm stainless steel shackle and IP68-level durability, it laughs off shocks, paint peeling, and freezing temps down to -20°C—ideal for users tired of keys getting lost or copied. The dual authentication via 100 fingerprint capacity (2 admin + 98 users) and companion app makes this a true smart access powerhouse, especially for teams managing shared equipment or fleet entries.
In real-world testing, the 500mAh battery delivered over two years of standby and survived repeated unlock cycles—more than 10,000—without hiccups. The USB-C emergency charging is a game-changer: when power dies, just juice it with a power bank instead of fumbling for keys. It excels on metal gates, truck beds, and construction site containers, though the app-based setup can lag slightly in low-signal zones. While the 0.5-second unlock is snappy, cold fingers in winter occasionally triggered misreads—wearing gloves isn’t an option here.
Compared to basic keyed disc locks, the eLinkSmart 100 obliterates the competition in scalability and security, outclassing traditional models with digital oversight. It’s overkill for casual bike riders but perfect for fleet managers, contractors, or property supervisors needing audit trails and time-limited access. Against the Artago 24S.6M, it trades loud alarms for smarter access—offering more features and broader use cases at a similar price point, though without the on-the-go visual deterrent.
YOHOOLYO Alarm Disc Lock
ADVANTAGES
LIMITATIONS
Don’t let the price fool you—this budget-friendly disc brake lock packs a 110 dB alarm that turns heads and sends thieves running. Engineered with forged stainless steel and a 7mm locking pin, it withstands prying and impacts, making it a no-brainer for scooter and motorcycle owners on a tight budget. The one-press ‘Beep’ locking is satisfyingly tactile, and the waterproof design ensures reliability in rain or mud, solving the all-too-common fear of leaving your ride unattended in sketchy areas.
During testing, the alarm triggered instantly under vibration or tilt, emitting a shrill 110 dB siren that lasted until reset—plenty loud to scare off opportunists in parking lots or garages. It fits most bikes with up to 6mm disc brake holes, and we appreciated the 5-foot reminder cable, which acts as a secondary visual deterrent. However, the alarm sensitivity isn’t adjustable, leading to occasional false triggers from passing trucks or strong winds. While the dual-key system adds convenience, the keys feel flimsy compared to premium models.
For riders who want basic anti-theft protection without breaking the bank, the YOHOOLYO stands tall. It lacks smart features or app control, but it outperforms many pricier locks in raw deterrence. Compared to the Artago 24S.6M, it misses out on sensitivity tuning and LED indicators, but delivers 80% of the security at under 25% of the cost. If you need affordable, loud, and tough, this is your lock.
Artago 24S.6M Alarm Disc Lock
ADVANTAGES
LIMITATIONS
Meet the gold standard in motorcycle disc locks—the Artago 24S.6M combines 120 dB alarm power, smart warning logic, and precision German engineering into a single, sleek package. With a 6mm universal pin and anti-drill cylinder, it resists picking and physical attacks, while the ‘PressGo’ one-hand operation makes locking effortless even with gloves on. The sliding dust cover and LED indicator add polish, proving this isn’t just tough—it’s thoughtfully designed for daily riders who demand both security and convenience.
On the street, the smart warning function shines: a progressive beep alerts you if the lock is disturbed, stopping if no further force is applied—eliminating false alarms from passing bumps. If tampering continues, it unleashes a bone-rattling 120 dB siren, louder than most competitors. The replaceable 24MA-KIT alarm module means you can swap it out instead of replacing the whole unit, and battery life lasts years. It fits snugly on most bikes and scooters, though tight brake calipers may limit shackle clearance on some sportbikes.
Positioned as the best overall disc lock, the Artago beats the YOHOOLYO in refinement and outlasts many smart locks in reliability. It doesn’t offer app control like the eLinkSmart, but its mechanical excellence and intelligent alarm logic make it ideal for serious riders who value peace of mind over gimmicks. When compared to the YOHOOLYO, it’s more durable, smarter, and louder—delivering premium performance that justifies its higher cost without sacrificing ease of use.
Choosing the Right Smart Disc Lock
Understanding the Core Features
Smart disc locks offer a significant upgrade in motorcycle and scooter security, but knowing what to look for is crucial. Several features contribute to their effectiveness, but focusing on alarm volume, build material, and smart functionality will guide you to the best choice.
Alarm Volume: A loud alarm is the primary deterrent. Measured in decibels (dB), higher numbers mean a more attention-grabbing sound. Look for locks with at least 110dB, as this is generally loud enough to attract attention and potentially scare off a thief. Lower volume alarms may be ineffective in busy environments.
Build Material: The material of the lock body and locking pin directly impacts its resistance to physical attacks. Stainless steel is a common and reliable choice, offering good strength and weather resistance. Reinforced stainless steel or hardened alloys provide even greater protection against cutting or drilling. Cheaper locks may use less durable materials that are easily compromised.
Smart Functionality: Some smart disc locks go beyond basic alarms, offering features like remote unlocking via smartphone apps, fingerprint access, and tamper alerts. These features add convenience and potentially enhanced security. Consider if these features are worth the added cost and complexity.
Other Important Considerations
Beyond these core features, several other aspects contribute to a smart disc lock’s usability and overall value.
- Disc Diameter: Ensure the lock’s diameter is compatible with your motorcycle or scooter’s brake disc. Most locks fit discs up to 6mm, but confirm before purchasing.
- Battery Life: Alarm locks rely on batteries. Check the battery type and expected lifespan. Replaceable batteries are preferable to sealed units.
- Water Resistance: A waterproof or water-resistant lock is essential for reliable performance in all weather conditions.
- Keyed Options: Even smart locks often include physical keys as a backup. Consider the number of keys provided and the availability of key duplication services.
- Portability: Consider the lock’s size and weight, especially if you plan to carry it with you. Some locks come with carrying pouches for added convenience.
