Resettable combination four foot chain lock

Updated 2026-09-05

This resettable combination lock provides a convenient security solution for e-bike owners and daily commuters. The four foot length offers ample reach for securing frames to various fixed objects. Utilizing a four-digit code, users can easily set and change their personal combination without the need for carrying physical keys during their rides.

Constructed with 7mm four-sided manganese steel links, the chain is designed to resist cutting and prying attempts. The integrated lock head design eliminates the vulnerability of a separate padlock, streamlining the locking process. A durable weather-resistant nylon sleeve covers the metal links to prevent scratches on the bicycle frame or components.

The flexible nature of the chain allows for compact storage when not in use, making it easy to wrap around a seat post or carry in a bag. It is particularly well-suited for quick stops in low to moderate crime areas. This model balances portability with the robust strength required for modern electric bicycles.
