Folding lock Kryptonite Evolution 790 Black Orange 900 mm Steel

The Kryptonite Evolution 790 Black Orange 900 mm is a folding lock constructed from hardened steel, offering a balance of rigidity and portability. At 900 mm length and approximately 1.5 kg weight, the lock folds compactly for transport and unfolds to secure bikes, scooters or other valuables to fixed objects. The set includes two keys and a durable locking mechanism finished in black and orange, designed for daily urban use and moderate outdoor exposure.

Advantages

This folding lock provides strong cut resistance due to its hardened steel links and reinforced joints while remaining more compact than a comparable U-lock. The articulated folding design reduces rattling in transit and simplifies mounting on a frame or in a bag. Inclusion of two keys ensures a spare for routine use or shared access, and the visible black-and-orange finish supports easy identification.

Suitable for

• Securing city and commuter bicycles to bike racks or posts
• Locking electric scooters, cargo bikes or trailers during short stops
• Protecting equipment in shared residential or workplace storage areas
• Use by riders who require a balance of security and portability

Key specifications

• Material: hardened steel folding links with protective coating
• Length: 900 mm (when unfolded)
• Weight: approximately 1.5 kg
• Finish: black and orange protective coating
• Locking mechanism: cylinder lock with two supplied keys

How to use

Unfold the lock and wrap the steel links around the bicycle frame and a fixed, immovable object such as a bike rack or lamppost. Insert the end of the lock into the cylinder and turn the key to secure; remove the key after locking. Keep one spare key in a safe location. When transporting, fold the lock into its compact form and use the included mounting bracket or place it in a bag to prevent contact with the frame finish.

Usage recommendations

For best results, lock the frame and at least one wheel to an immovable object and position the lock away from the ground to make leverage attacks more difficult. Store the spare key separately from the primary key and periodically clean and lubricate the cylinder to maintain reliable operation.
