After meeting TMD Locks at the Bike2Business conference, I was confident in the lock’s protection for my e-bike. The alarm was impressively loud. My pre-order is now confirmed.

After two recent bike thefts in Amsterdam, I was looking for a high quality lock. At the Bike2Business conference, I spoke with TMD Locks and tested the lock myself. In addition to its enhanced security, it opens and closes very smoothly.

As a tech enthusiast, I was immediately impressed by TMD Locks. The combination of smart features, built-in alarm, and overall design made me pre-order right away.
Truly the next generation of locks
A chain lock designed by thinking out-of-the-box. Without restrictions.
A keyless experience
Open the lock with a press of the button when your phone is nearby. No more keys, just fast and secure access.
Intelligent alarm
Rest assured that the built-in 100dB alarm will scare away any thieves that dare to touch your lock.
Don’t be fooled by its soft outside
While the lock body is designed to withstand the harshest conditions and attacks, it is also soft on the outside to prevent your ride from getting damaged.
Soft silicon outside
The soft exterior of the lock body keeps your ride scratch-free, and helps to prevent damage from accidental droppings, while providing a comfortable feel.
Hardened steel enclosure
All the lock's vital components are protected by a steel hardened enclosure within the lock body, which ensures that it's resistant against brute force attacks.
Luxury & security in a sleeve
The sleeve sets a new standard with its light weight, flexibility and soft outside. While the use of innovative materials offers unparalleled protection.
Technical polyester
By double braiding the polyester outer layer, it is very durable and much less prone to tearing.
Dyneema & Kevlar
The use of Dyneema and Kevlar, the same advanced materials used in maritime gear and bulletproof vests, make it both cut and fire resistant.
Hardened steel chain
You can barely feel the specially hardened manganese alloy steel chain. But it really is there.

No matter what kind of ride you have, we have the right lock for you.
