Sportneer Bike Lock: 5 Digit Combination High Security Anti Theft Bike Chain Lock - 3.2/3.6/4ft Heavy Duty Keyless Bicycle Lock for Bike

1. Sportneer Bike Lock: 5 Digit Combination High Security Anti Theft Bike Chain Lock – 3.2/3.6/4ft Heavy Duty Keyless Bicycle Lock for Bike

  • Brand: Sportneer
  • Manufacturer: Sportneer

The Sportneer Bike Lock is an affordable, keyless, and highly versatile chain lock that boasts a 5-digit combination system with 100,000 possible combinations. Its manganese steel construction ensures durability and resistance against cutting and sawing, while the scratch-resistant polypropylene cover protects both the lock and your bike’s paint. This model is available in multiple lengths, making it suitable for locking multiple bikes or securing other outdoor equipment. It’s a great choice for cyclists seeking convenience and reliability at a budget-friendly price point.

In testing, the Sportneer lock performed admirably in terms of security and ease of use. The combination mechanism was smooth and intuitive, allowing users to set and reset passwords effortlessly. Its lightweight design makes it portable, though the 4mm thickness may not deter determined thieves as effectively as thicker locks. The dustproof cap is a thoughtful feature, but users should ensure compatibility with their bike frame or tires due to the 1.3-inch lock head diameter. Overall, this lock is ideal for casual cyclists who prioritize convenience and affordability.

Pros

  • Affordable price point
  • Keyless convenience with resettable combination
  • Durable manganese steel construction
  • Scratch-resistant cover and dustproof cap
  • Versatile applications for bikes and other equipment

Cons

  • Thinner chain may not deter professional thieves
  • Lock head diameter may not fit all bikes

Master Lock Cable Lock

2. Master Lock Cable Lock

  • Brand: Master Lock
  • Manufacturer: Master Lock

The Master Lock Cable Lock features a 6-foot braided steel cable with a 4-digit resettable combination mechanism. Its vinyl coating prevents scratches, while the flexibility of the cable makes it easy to secure bikes and other outdoor equipment. As the #1 bestseller in bike cable locks, this product is designed for basic theft deterrence rather than high-security applications. It’s lightweight and portable, making it suitable for casual cyclists who park their bikes in low-risk areas.

During testing, the Master Lock Cable Lock was straightforward to set up and operate. Its 13mm diameter provided moderate resistance against cutting, though it’s not as robust as U-locks or chains. The combination mechanism worked reliably, and its flexibility allowed for versatile locking configurations. However, users seeking maximum security may find this lock insufficient for high-theft areas. It’s best suited for temporary use or as an additional layer of security alongside a more robust lock.

Pros

  • Flexible and lightweight design
  • Resettable combination for convenience
  • Protective vinyl coating prevents scratches
  • Affordable mid-range price

Cons

  • Not suitable for high-theft areas

  • Brand: Sportneer
  • Manufacturer: Sportneer

The Sportneer Heavy Duty U Lock combines robust security with portability. Featuring a 17mm alloy steel shackle and a zinc alloy lock core, this lock resists cutting, smashing, and drilling. It comes with a 5-foot steel cable for securing additional components, making it ideal for urban environments. The silicone coating protects against scratches, while the included mounting bracket ensures convenient transportation. This lock is geared toward cyclists who require heavy-duty protection for their bikes.

In our tests, the Sportneer U Lock stood out for its durability and ease of use. The 17mm shackle provided exceptional resistance against mechanical attacks, and the inclusion of two keys adds a layer of convenience. Its mounting bracket was simple to install, though the weight of the lock (2.86 pounds) may deter some users from carrying it on longer rides. The 5-foot cable is a welcome addition for securing wheels or accessories, making this lock a versatile choice for city commuters and electric bike owners.

Pros

  • Heavy-duty construction resists cutting and smashing
  • Includes 5-foot steel cable for added security
  • Scratch-resistant silicone coating
  • Convenient mounting bracket
  • Two keys for backup

4. Master Lock Bike Lock Cables with Key

  • Brand: Master Lock
  • Manufacturer: Master Lock

The Master Lock 3-Pack Cable Locks offer a budget-friendly solution for cyclists seeking basic security. Each lock features a 6-foot braided steel cable with a vinyl coating to prevent scratches. The keyed-alike design allows one key to open all three locks, making it convenient for families or individuals with multiple bikes. The colorful cables also make identification easier, adding a touch of practicality.

While this set is well-suited for low-risk areas, its 8mm cable diameter provides only basic resistance against cutting. The locks are lightweight and easy to use, but they lack the robust security features of higher-end models. These locks are best for securing bikes in low-theft areas or for temporary use during quick errands. The keyed-alike feature adds convenience, though carrying multiple locks may be cumbersome for some users.

Pros

  • Budget-friendly price
  • Keyed-alike design for convenience
  • Color-coded cables for easy identification
