This set includes two braided, self-coiling cables with a 4-digit resettable combination. The flexible design and self-storage coil make it easy to keep spare locks handy for multiple bikes or gear. Best for price-conscious buyers who need quick, keyless access. Caution: security relies on the strength of the cable; avoid relying on these for high-value, long-term storage in high-risk areas.
Best for: households with multiple bikes or casual riders who want simple, portable security.

It’s positioned as a practical solution for households with children, offering simple, reliable access while preventing unwanted opening.

The laminated housing and anti-theft core increase pry resistance, and the waterproof cap protects the keyhole. Best for outdoor installations where exposure to rain and elements is a concern. Limitation: bulkier than some pocket-friendly options, so it’s heavier to carry for portable use.
Best for: securing outdoor property where weather exposure is a factor and higher security is needed.
RESET-201 4 Digit Combination Padlock
This long-cable design provides 12 inches of flexible reach for awkward latch points, such as trash cans, lockers, and helmets. The 4-digit combination allows keyless access, reducing the need to manage keys. Best for users needing a compact, versatile cable lock with a longer reach for awkward applications. Limitation: suitable for lightweight items; extremely high-value security may require stronger hardware.
Buying Guide
What should you check before buying?
Material quality is central. Look for hardened steel, stainless steel, or weatherproof coatings to prevent rust and cut-through attempts. Measure the length you need to reach latch points without stressing the lock or chain.
Lock type considerations
- Chain vs. cable: Chains offer higher cut resistance but weigh more. Cables provide flexibility and portability but can be cut with a tool if the diameter is small.
- Keyed vs. combination: Keyed locks are simple but require key management. Combinations avoid keys but can be forgotten; resettable options improve usability.
Usage scenarios
For bikes, prioritize length and portability. For cabinets and appliances, consider locks that install quickly and do not damage surfaces. For outdoor gates, choose weatherproof options with robust cores.
Security vs. convenience balance
Stronger materials and thicker chains improve security but reduce portability. Assess where the lock will be used most often and whether you need frequent access or longer-term protection.
Maintenance tips
- Keep locks dry after exposure to rain and wipe away dirt to prevent corrosion.
- Lubricate mechanisms periodically with graphite or light oil, avoiding heavy greases that attract dust.
- Store spare keys or set a memorable combination in a secure location.
Frequently Asked Questions
- What lock is best for bicycles? A compact, heavy-duty chain or braided cable with a hardened core tends to offer strong security for bikes when paired with a reliable U-lock or additional lock.
- Are combination locks safer than keyed ones? It depends. Combination locks eliminate key management but can be forgotten. Keyed locks provide quick access if you carry a key correctly; choose what fits your routine.
- Can a weatherproof coating prevent rust? Yes, protective coatings significantly improve outdoor durability by reducing moisture exposure and wear.
- Should I use multiple locks? Using more than one lock can deter thieves by creating additional barriers and slowing their attempts, especially when targeting different access points.
- Is a longer cable lock better? Longer cables offer reach and flexibility but may be easier to cut if the cable diameter is thin. Choose thickness that matches security needs.
- How do I choose the right length? Measure the points you intend to secure and pick a lock that covers both points with some slack for mounting.
