What to Compare Before Buying
- Reach: Compare the 3.2 ft chain length with the route around your bike and the object you intend to secure it to.
- Clearance: The lock head is 1.3 inches in diameter. Check the available gap before relying on threading it through a wheel or other opening.
- Combination use: This lock does not use a key. Consider whether you can keep track of the combination you set.
Compatibility, Size and Fit
The listing describes the lock for bicycles and also names motorcycles, scooters, doors, and gates. Fit depends on the chain reaching around the item and its locking point. If the lock head will not pass through a wheel gap, the listing suggests wrapping the chain around the bike instead.
Setup and Correct Use
The listed initial combination is 00000. To reset it, the listing says to set the wheels to the correct unlocking combination and turn the reset dial 90 degrees. Keep the chosen combination available to you, since the lock is keyless.
Before You Decide
Check that the 3.2 ft chain reaches your intended locking point and that the 1.3-inch lock head fits any opening you plan to use. Confirm that a single lock and a combination mechanism suit your needs.
