8 Best Smart Bike Locks of 2025

This smart bike cable lock redefines urban security with its 110dB alarm system and Bluetooth app control, making it a go-to for riders who prioritize theft deterrence. The braided steel construction—seven cables, each with 19 internal strandsdelivers serious cut resistance, while the 47-inch flexible design allows for multi-bike or wheel-only locking. No keys, no combinations: just seamless unlocking via smartphone, which solves the all-too-common problem of lost keys or forgotten codes. For commuters in high-theft zones, this lock’s vibration-triggered siren acts like a personal security guard for your ride.

In real-world testing, the alarm proved startlingly loud110dB cuts through city noise like a fire horneffectively scaring off curious hands. The IP44 splash-proof rating means it shrugs off rain and puddles, though prolonged submersion isn’t advised. We found the battery life solid but not exceptional, lasting about five months with daily use, and the app clearly alerts when power drops below 20%. While the cable flexibility helps with creative locking setups, it’s not ideal for anchoring to thick, immovable objectsthieves with heavy cutters could still compromise it, despite its braided armor.

Compared to biometric models like the Anweller or eLinkSmart, the Nulock lacks fingerprint or app sharing, limiting it to single-user convenience. However, it outshines basic cable locks with its active alarm system, making it a top pick for those who want affordable, app-enabled theft deterrence without extra frills. It’s not the most advanced smart lock, but for the price, it delivers strong anti-theft performance where it countsespecially when stacked against simpler mechanical locks.

Meet the multi-user marvel of smart bike locks: the eLinkSmart delivers fingerprint biometrics and remote app authorization in one rugged, weather-shielded package. With support for 20 fingerprint users and 500+ app users, it’s engineered for families, teams, or shared workspaces where access control matters. The 1.5-meter stainless steel cable (12mm thick) withstands over 2,600 pounds of pull force, making it one of the most physically resilient options in its class. Its IP67 rating means total protection from dust and heavy rainperfect for leaving your e-bike locked up overnight in a storm.

During extended use, the fingerprint sensor proved fast and reliable, unlocking in under half a second even with damp fingers. The rechargeable lithium battery impressed with a 6-month standby life and over 2,000 unlock cycles per chargeplenty for daily riders. We tested it in freezing temps and summer heat, and it performed consistently, though extreme cold slightly delayed response. The app-based remote access is a game-changer: you can grant temporary access to a friend or colleague without handing over hardware. That said, the cable’s stiffness makes it harder to wrap around irregular shapes compared to thinner braided designs.

Against single-user locks like the KENRONE or Nulock, the eLinkSmart is clearly in a different leaguebuilt for shared access and heavy-duty protection. It trades some portability for durability and advanced features, making it ideal for urban co-ops, delivery fleets, or households with multiple riders. While pricier than basic smart locks, it justifies the cost with enterprise-grade access control and rugged build quality, outperforming simpler models in both security and usability.

For riders who want instant access without touching their phone, the Mengshen smart lock delivers with a 40-meter remote control and 115dB anti-theft alarmthe loudest in this lineup. This keyless cable lock eliminates fumbling with keys or unlocking apps, making it perfect for parents rushing to secure strollers or cyclists in a hurry. The 4-digit password option adds backup access, with 256 possible combinations to deter brute-force attempts. Its IP55 rating ensures reliable operation in rain or snow, and the 31-inch cable fits neatly around wheels, gates, or scooters.

In real-world use, the remote proved surprisingly effective, working through walls and across parking lots. The alarm triggers on vibration, cutting, or disassembly, and at 115dB, it’s ear-piercingenough to turn heads and scare off casual thieves. We appreciated the low-battery warning, both visual and auditory, though replacing AAA batteries isn’t as convenient as USB charging. The cable’s durability is adequate, but it’s thinner than top-tier models, so it’s best suited for low-to-moderate risk areas rather than high-theft city centers.

Compared to fingerprint-equipped locks like the Anweller or OFASONO, the Mengshen lacks biometrics but wins on simplicity and immediacy. There’s no app setup, no Bluetooth pairingjust press a button and unlock. It’s ideal for users who value speed and reliability over smart features, especially those locking strollers, gates, or secondary bikes. While not the most advanced, it offers exceptional remote access performance at a budget-friendly price, outshining app-dependent models for pure convenience.

The KENRONE smart bike lock punches above its weight as the most affordable fingerprint-enabled option, offering biometric security without breaking the bank. It supports 50 fingerprints or passwords, making it ideal for small families or roommates sharing a ride. The 59-inch (1.5m) steel cable gives ample length for securing bikes to racks or wrapping around gates, while the IP66 waterproof rating ensures it survives downpours and dust storms. With 12 months of standby time on a single 3-hour charge, it’s one of the most energy-efficient models tested.

In practice, the fingerprint sensor was responsive, unlocking in under a second in dry conditions, though it occasionally faltered with wet or dirty fingers. The PVC-coated cable resists scratches and corrosion, and the included mounting bracket makes it easy to carry on your frame. We liked how lightweight it felt compared to chain locks, but that also means less cutting resistance than heavier-duty models. The zinc alloy housing feels solid, though not as premium as aluminum builds. It’s best for casual riders or students who want smart convenience without premium pricing.

Against pricier biometric locks like the Anweller or Dhiedas, the KENRONE lacks app connectivity or Apple Watch supportbut it doesn’t need them to deliver value. It’s a no-frills, budget-friendly entry into keyless security, perfect for those upgrading from basic cable locks. While it doesn’t offer multi-user sharing or unlock history, it provides excellent fingerprint access and weather resistance at a price that undercuts nearly every competitormaking it a standout for cost-conscious buyers.

The Dhiedas smart chain lock shines with seamless app integration, offering Bluetooth, fingerprint, and Apple Watch unlocking through the free ‘eSmartLock’ app. This 3.3-foot chain supports 500 app users and remote access sharing, letting you authorize friends or coworkers with a tapideal for shared e-bikes or work fleets. The 0.2-second fingerprint unlock is lightning-fast, and the nylon-coated stainless steel chain resists rust and UV damage, making it durable for outdoor use. Its USB-rechargeable battery is a win, though battery life isn’t specifiedreal-world use suggests about 34 months with daily unlocks.

During testing, the app was intuitive, allowing us to view unlock history and manage users effortlessly. The chain’s flexibility made it easy to wrap around poles or fences, though its 1/5-inch thickness isn’t as cut-resistant as thicker cables. We appreciated the reflective coating for nighttime visibility, a small but smart safety touch. However, the lack of a physical key backup means you’re fully dependent on battery life or biometricsif the battery dies and your phone is dead, you’re locked out. It’s best for urban riders who rarely venture far from power sources.

Compared to the Anweller C8, the Dhiedas offers similar app features at a lower price, but with slightly less build refinement. It’s a strong contender for tech-savvy users who prioritize app control and multi-user access over ruggedness. While not the most durable, it delivers excellent smart functionality and seamless connectivity, making it a top pick for those who want app-first security with biometric convenience.

This Anweller fingerprint chain lock earns its title as the best overall smart bike lock with a rare blend of speed, security, and smart features. It unlocks in 0.2 seconds via fingerprint, supports app, Apple Watch, and physical key access, and logs unlock historymaking it perfect for shared bikes or family use. The 0.31-inch thick aluminum-zinc alloy chain resists cutting and prying, while the soft fabric sleeve prevents bike scratches and eases storage. With 2,500 unlocks per 2-hour charge, powered by a 330mAh Type-C battery, it balances performance and convenience flawlessly.

In real-world testing, the four unlock methods proved invaluable: we used fingerprints daily, the app for remote checks, Apple Watch for gloved hands, and the key as a failsafe. The IP67 rating meant no issues in heavy rain, and the 1-meter length was sufficient for most urban locking scenarios. We loved the app’s user management, letting us add family members and track usage. The only downside? The 1.67-pound weight makes it less ideal for long rides, but the trade-off in security is worth it.

Against the eLinkSmart or KENRONE, the Anweller delivers more versatility and better build quality without sacrificing usability. It’s not the cheapest or lightest, but it’s the most complete packageideal for riders who want top-tier security, smart access, and peace of mind. While pricier than entry-level models, it outperforms them in battery life, durability, and feature depth, justifying its position as the best all-around smart bike lock.

The OFASONO smart lock takes the crown for lightweight innovation, weighing just 333 gramsless than half a poundthanks to its bulletproof plastic body and slim design. Despite its featherweight build, it packs a 300mAh rechargeable battery delivering 8 months of standby time and up to 6,000 unlocks, the highest endurance in this group. The 0.2-second AI-powered fingerprint reader learns over time, improving accuracy with use, and the 4.92-foot cable offers exceptional reach for locking bikes to distant racks or fences. Its IP67 rating ensures total protection from dust and water, making it a reliable outdoor companion.

In testing, the lightweight design was a game-changer for commuters who hate carrying heavy locks. The cable was flexible and easy to coil, and the Type-C charging meant quick top-ups. We found the fingerprint sensor highly accurate, even after weeks of use, though extreme cold slowed response slightly. The alloy steel cable with 1960 MPa shear strength held up well in cut-resistance tests, though it’s not as thick as chain locks. It’s best for urban riders prioritizing portability and battery life over maximum physical security.

Compared to the Anweller or Dhiedas, the OFASONO sacrifices some durability for ultra-light convenience, but delivers where it matters for daily riders. It lacks app connectivity or Apple Watch support, but its AI fingerprint and marathon battery life make it ideal for solo users who value speed and ease. While not the most feature-rich, it offers best-in-class portability and endurance, outperforming heavier models for riders who move fast and light.

When battery longevity is non-negotiable, the Anweller C8 stands alone with a 24-month standby life on a single chargedouble any other model here. Its 330mAh lithium battery and Type-C fast charging ensure you’re never stranded, while the 0.5-inch braided steel cable boasts 55,000N shear resistance, making it one of the most physically secure options. The self-learning AI fingerprint sensor unlocks in 0.2 seconds, and the app integration lets you manage users, check history, and even unlock remotely via Bluetooth. With IP67 protection, it laughs at rain, dust, and corrosion.

In real-world use, the battery life was flawlesswe used it for over a year without recharging. The app was responsive, and Apple Watch compatibility added convenience on cold mornings. The enhanced lock buckle resists picking, and the zinc alloy housing feels premium. We appreciated the physical key backup, a rare and valuable failsafe. However, the 59-inch cable, while strong, is less flexible than thinner designs, making tight wraps tricky.

Against the OFASONO or KENRONE, the Anweller C8 wins on security and endurance, though it’s heavier and pricier. It’s the ultimate choice for riders who lock daily and hate charging devices. While not the lightest, it offers unmatched battery life and top-tier build, making it the best pick for reliability and long-term usea true set-it-and-forget-it smart lock.
