How to Choose the Right E-Bike Lock: 2025 Security Guide

With electric bikes representing a significant investment—often $1,500 to $5,000 or more—selecting the right lock is crucial for protecting your valuable ride. The e-bike theft landscape has evolved dramatically in recent years, with thieves increasingly using power tools like angle grinders to defeat traditional locks in seconds.

Fortunately, lock technology has advanced to meet these challenges. This comprehensive guide will help you navigate the complex world of e-bike locks to select the perfect security solution for your specific needs, budget, and riding habits.

Understanding Security Ratings: Your First Decision Factor

When shopping for an e-bike lock, security ratings provide a standardized way to evaluate protection levels. The most widely recognized rating system is from Sold Secure, an independent, not-for-profit organization that rigorously tests locks against various attack methods.

Sold Secure Ratings Explained

Sold Secure categorizes locks into four levels:

1. Bronze: Basic protection against opportunistic theft (not recommended for e-bikes)
2. Silver: Medium security suitable for lower-value bikes in low-risk areas
3. Gold: High security for valuable bikes and moderate-risk areas
4. Diamond: Maximum security, specifically includes testing against angle grinders

For e-bikes specifically, Sold Secure has created a category called "Powered Cycle," which recognizes the higher value of electric bikes compared to traditional bicycles.

Here's what you need to know about these ratings in relation to e-bike security:

• Sold Secure Powered Cycle Gold is equivalent to Sold Secure Pedal Cycle Diamond - both provide the same level of protection
• Most insurance policies require at least a Sold Secure Gold-rated lock for e-bikes
• The Diamond rating was introduced specifically to address the growing threat of angle grinder attacks

According to security experts, e-bike owners should invest in locks rated at a minimum of Sold Secure Gold, with Diamond being preferable for high-value e-bikes or high-risk areas.

Other Important Security Certifications

While Sold Secure is the most common standard in the US and UK, other certifications to look for include:

• ART Rating (Netherlands): Rates locks from 1-5 stars, with 4-5 stars providing excellent security
• VdS (Germany): A rigorous testing standard similar to Sold Secure
• Manufacturer Security Scales: Some manufacturers like ABUS and Kryptonite use their own 1-10 security scales

Types of E-Bike Locks: Strengths and Weaknesses

Different lock types offer varying levels of security, convenience, and usability. Here's a breakdown of your main options:

U-Locks/D-Locks

Pros:

• Rigid construction resistant to leverage attacks
• Compact and relatively easy to transport
• Usually provide the best security-to-weight ratio
• Many newer models offer angle grinder resistance

Cons:

• Limited locking area may make securing both wheels challenging
• Less versatile for oddly shaped bike racks or posts

For e-bikes, look for U-locks with shackles at least 14mm thick, with 16mm or thicker providing better security. Diamond-rated options like the MoVcan Guardian U-Lock or equivalents from brands like Kryptonite, ABUS, or LiteLok offer the highest security.

Chain Locks

Pros:

• Flexible for securing around awkward objects
• Can often secure both wheels and frame with a single lock
• Available in various lengths for different security needs
• Good chain locks are extremely difficult to cut

Cons:

• Heavier than other lock types
• Can be cumbersome to transport
• Quality chains with hardened links are expensive

For e-bikes, choose chains with links at least 10mm thick made of hardened steel, preferably with a protective sleeve to prevent damage to your bike's finish. Our MoVcan Fortress Chain provides Diamond-rated security while being optimized for e-bike frames.

Folding Locks

Pros:

• Compact when folded for easy transport
• More flexible than U-locks but more rigid than chains
• Often come with frame mounts for convenient carrying
• Newer models offer impressive security ratings

Cons:

• Traditionally less secure than quality U-locks or chains
• Pivot points can be vulnerable to certain attacks
• Higher-security versions tend to be heavier

Folding locks have improved significantly in recent years, with some now achieving Gold ratings. However, for primary e-bike security, they're best used as secondary locks unless you select a high-security model like the ABUS Bordo Granit X-Plus.

Cable Locks

Pros:

• Lightweight and highly flexible
• Inexpensive compared to other options
• Useful as secondary security for wheels or accessories

Cons:

• Easily defeated with basic cutting tools
• Not suitable as primary security for e-bikes
• Few models achieve even Bronze security ratings

Cable locks should never be used as the primary security for an e-bike. They can be useful as secondary locks to secure wheels or as a deterrent during very brief stops when you maintain visual contact with your bike.

Angle Grinder Resistance: The Game-Changer for 2025

The biggest advancement in e-bike security for 2025 is the development of locks specifically designed to resist angle grinder attacks. These attacks had rendered even the strongest traditional locks vulnerable in just seconds.

How Angle Grinder-Resistant Locks Work

The newest generation of high-security locks utilize innovative materials and designs to dramatically extend the time required to cut through them:

1. Composite Materials: Locks like the LiteLok X1 and X3 use a ceramic composite material called Barronium that wears down grinder discs as they attempt to cut through
2. Graphene Reinforcement: The Hiplok D1000 incorporates graphene, one of the strongest materials known, to resist cutting
3. Tungsten Carbide Coatings: Some locks use the same hardened material found in cutting tools themselves to resist grinder attacks
4. Multiple Layers: By combining different materials, manufacturers create locks that may require multiple discs to cut through

Top Angle Grinder-Resistant Options for 2025

Based on extensive testing by security experts, the following locks have proven most effective against angle grinder attacks:

1. OnGuard RockSolid 8590: Despite its relatively light weight (1.3kg), this lock has consistently performed extraordinarily well against angle grinders, requiring multiple discs to cut through
2. LiteLok X3: This Diamond-rated lock offers excellent reach and consistently strong performance against grinder attacks
3. Hiplok D1000: Utilizing a graphene composite material, this lock has defeated multiple grinder discs in tests
4. ABUS Granit Super Extreme 2500: Features a tungsten carbide shell specifically designed to deflect angle grinders

Practical Considerations: Beyond Security Ratings

While security is paramount, several practical factors should influence your lock selection:

Size and Weight

E-bikes are already heavier than traditional bicycles, so lock weight matters. Balance these considerations:

• Heavier locks generally offer better security but are more cumbersome to carry
• Consider where you'll store the lock while riding (frame mount, pannier, backpack)
• For commuters, leaving a heavy lock at your regular destination can be practical

Usability and Convenience

The best lock is one you'll actually use every time. Consider:

• Ease of operation, especially in cold weather (keyless or covered keyways help)
• Whether the lock comes with a frame mount or carrying solution
• Key vs. combination mechanisms (keys offer better security but can be lost)

Multiple Lock Strategy

Security experts recommend using at least two different types of locks for maximum protection:

1. Primary Lock: A high-security U-lock or chain to secure the frame and rear wheel to an immovable object
2. Secondary Lock: A second lock to secure the front wheel and any other removable components

This approach significantly increases the time and tools required for theft, making your bike a less attractive target.

Insurance Requirements: Protecting Your Investment

Most e-bike insurance policies specify minimum lock requirements for coverage to apply in case of theft. Typically:

• E-bikes valued under $1,500: Minimum Sold Secure Silver or equivalent
• E-bikes valued $1,500-$3,000: Minimum Sold Secure Gold or equivalent
• E-bikes valued over $3,000: Sold Secure Diamond/Powered Cycle Gold or equivalent

Always check your specific policy requirements before purchasing a lock, as insurance companies may also maintain lists of approved lock models. Review your MoVcan warranty and protection plan for our specific security recommendations.

Proper Locking Technique: Making the Most of Your Lock

Even the best lock provides minimal protection if used incorrectly. Follow these best practices:

1. Lock to something immovable that cannot be easily cut or removed
2. Position the lock off the ground to prevent leverage attacks
3. Minimize space inside the lock to prevent insertion of prying tools
4. Use the "Sheldon Method" - secure rear wheel and seat tube with primary lock
5. Remove or secure easily detachable components like batteries, displays, and lights
6. Vary your parking routine if you regularly park in the same location

Budget Considerations: Value for Money

E-bike security is an area where spending more typically delivers better protection. Industry experts recommend investing 10-15% of your e-bike's value in security.

While smart features offer convenience and additional security, they should complement rather than replace physical security. The best smart locks combine robust physical protection with smart features for comprehensive security.

Conclusion: Making Your Decision

Selecting the right e-bike lock involves balancing security, convenience, and cost based on your specific circumstances:

1. Assess your risk level: Consider your location, parking duration, and bike value
2. Check insurance requirements: Ensure your lock meets policy specifications
3. Consider your usage patterns: Will you carry the lock or leave it at a destination?
4. Prioritize angle grinder resistance: In high-risk areas, this is essential for 2025
5. Plan a multi-lock strategy: Different locks for different scenarios

Remember that no lock can guarantee absolute security, but the right lock used properly will significantly reduce theft risk and provide peace of mind.
