Bicycle Lock: FAQ

How do I choose the right size lock for my bike frame?

Measure your frame clearance and the typical objects you lock to. U-locks need specific shackle lengths to minimize leverage attacks, while folding locks offer more flexibility for awkward angles.

How can I tell if the lock material is truly cut-resistant?

Look specifically for 'heat-treated hardened steel' or 'manganese steel' in the specifications. Avoid generic zinc alloys for primary security as they are easily cut with bolt cutters.

What locking mechanism is hardest to pick?

Disc detainer cylinders are superior to standard pin tumblers and offer higher resistance against picking. Double-locking bolt mechanisms also prevent the shackle from being twisted open if cut once.

Are heavy chain locks expensive to ship due to weight?

Heavy-duty chains are weighty, which can affect logistics, but many top sellers absorb this cost. Always filter for 'Free Shipping' to ensure the total price remains competitive.

Recommendations for buyers

✓
Shackle Thickness
For high-risk areas, ensure the shackle or chain link diameter is at least 13mm-16mm to resist manual bolt cutters.
✓
Core Mechanism
Prioritize locks with 'C-grade' or disc detainer cylinders, which are significantly harder to pick than standard keys.
✓
Mounting Options
Heavy locks are a burden to carry in a backpack; look for models that include a sturdy, rattle-free frame bracket.
✓
Weatherproofing
Check for a dust cover over the keyhole and a rubberized or silicone coating on the shackle to prevent rusting and scratching your bike frame.
