Kryptonite Evolution 1090 Integrated Bicycle Chain Lock, 3-Foot Heavy-Duty 10mm Manganese Steel Security with Sold Secure Gold Rating, Weather-Resistant Nylon Sleeve, and 3 Keys for E-Bikes, Scooters, and Motorcycles

Product Overview

The Kryptonite Evolution 1090 is a 3‑foot integrated bicycle chain lock designed for use with e‑bikes, scooters, and motorcycles. It features a heavy‑duty chain constructed from 10 mm manganese steel, a material known for its strength and resistance to cutting tools. The lock includes a weather‑resistant nylon sleeve that protects the chain from environmental exposure. Three keys are supplied, allowing the chain to be engaged and disengaged in multiple configurations.

Chain and Construction

The chain is composed of 10 mm manganese steel links, each link forged into a profile that resists shear and impact. The steel’s composition enhances toughness while keeping the chain’s weight manageable for everyday handling. The integrated lock design incorporates a central lock body that mates securely with the chain, eliminating the need for an external keyring or padlock. The lock body is engineered to interface directly with the chain links, creating a single, continuous security system.

• Chain Length: 3 feet
• Link Diameter: 10 mm
• Material: Manganese steel
• Lock Body: Integrated with chain

Security Certification

The lock carries a Sold Secure Gold rating, a designation that reflects compliance with the Sold Secure standard for lock security. This rating is awarded based on tests that evaluate the lock’s resistance to common burglary tools and techniques. The rating provides an objective measure of the lock’s performance relative to the standard’s criteria.

Weather‑Resistant Sleeve

Enclosed within the lock’s housing is a weather‑resistant nylon sleeve. The sleeve’s coating prevents moisture from reaching the steel links, thereby reducing the likelihood of rust and corrosion. The sleeve also offers a degree of protection against abrasion caused by contact with rough surfaces. Because it is made of nylon, the sleeve remains flexible and does not compromise the lock’s structural integrity.

Key Set

Three distinct keys are included with the lock. Each key is designed to interact with a different locking point on the integrated lock body, providing versatility in how the chain can be secured. Users can choose the key that best suits their locking configuration, whether that involves securing a bike to a single stand or attaching multiple vehicles to a common anchor point.

Compatibility

The lock’s specifications make it suitable for securing electric bicycles, scooters, and motorcycles. Its 3‑foot length allows a range of anchor points, while the 10 mm steel links can accommodate the larger frame sizes that are common among these vehicle types. Users should confirm that their vehicle’s frame and anchor points are compatible with a chain of this length and diameter.

Installation and Use

To install the lock, the user first threads the 3‑foot chain through the chosen anchor point. The integrated lock body is then engaged with the chain links by inserting the appropriate key and turning the key to lock the mechanism. The lock body remains fixed to the chain, so the user can move the vehicle without removing the lock. When the vehicle is to be moved, the user selects the matching key to unlock the lock body, disengaging the chain.

Maintenance

Regular inspection of the chain and lock body is recommended. Look for visible signs of wear on the chain links or the lock body’s locking surfaces. If any link appears worn or bent, it should be replaced to maintain the chain’s integrity. The nylon sleeve can be wiped clean with a damp cloth; avoid harsh chemicals that may degrade the sleeve material. Because the chain is made of manganese steel, occasional lubrication of the chain links can reduce friction, though it is not required for operation.

Summary

The Kryptonite Evolution 1090 provides a 3‑foot, heavy‑duty chain lock with 10 mm manganese steel links, a weather‑resistant nylon sleeve, a Sold Secure Gold rating, and a set of three keys. Its design is tailored for e‑bikes, scooters, and motorcycles, offering a secure, integrated solution for vehicles that require a robust locking system. The lock’s construction and certification deliver a clear understanding of its security level, while the accompanying key set allows flexible deployment across a range of vehicle types.
