Locking your bike has never felt this good
TMD Chain Lock
A smarter way to lock
Your phone is your key
Unlock with a simple press of the lock’s button when your phone is nearby. No keys, no fumbling.
Built-in alarm
A powerful 100 dB alarm sounds when tampering is detected, adding an active layer of protection that helps deter unwanted attention.
Soft, tough and light
A soft exterior helps prevent scratches, while the strong, lightweight and flexible sleeve makes the lock easy to handle and carry.
Complete control with the app
The TMD Locks app lets you do so much more than just opening your lock. Manage access, keep track of activity and always know where your lock was last seen - all from one simple, intuitive app.
Manage access
Give friends and family access to your lock without handing over a key. Share access directly from the app and stay in control of who can use it.
Activity insights
See when your lock was used and by whom. Keep track of your own activity and any activity from people you’ve shared access with.
Find your lock
See the last known location of your lock directly in the app, so you can keep track of where it was last used.
More locks coming soon
The TMD Ring Lock and TMD U-Lock are coming soon. Each brings the same keyless experience, thoughtful design and uncompromising approach to bike security.
