Master Lock 8200EURDPRO

The Master Lock brand bike lock is a security solution that falls at the intersection of the mid-range and advanced price segments. The accessory is positioned as a universal model that can be used not only with bicycles but also with scooters, baby strollers, and affordable personal electric transport. The form factor of the Master Lock 8200EURDPRO resembles handcuffs with two clamps: one locks onto the frame, and the other onto various fixed objects (bike rack stands, railings, etc.).

The cuff length reaches 36 cm, and the segments themselves are made of hardened steel; it is claimed that they are extremely difficult to cut. For storage, the model folds in half, taking up minimal space and fitting not only in a bag or backpack but also in many clothing pockets. A standout feature is the ability to lock without a key (the cuffs snap shut), so there's no need to take it out unnecessarily. The durability of the accessory is confirmed by a limited lifetime warranty, and its decent anti-theft properties are guaranteed by a Bronze certificate from the British organization Sold Secure, which specializes in testing bicycle locks and preventatives.
