DIRECT ANSWER

A Tuya Smart chain bicycle lock combines a physical chain and lock body with fingerprint access and Bluetooth functions supported by its Tuya configuration.

C3 application

BioLock C3 is designed to wrap around bicycle frames, gates or shared equipment and a fixed anchor. The chain format offers more positioning flexibility than a short padlock shackle.

Fingerprint access avoids carrying a key during routine use.

Connected does not mean invulnerable

App management can help shared users, but resistance still depends on materials, construction and correct locking. Choose a parking strategy appropriate to the value and local theft risk.
