Electric bikes represent a significant investment, and securing them effectively is more crucial than ever. Unlike traditional bicycles, ebikes often have unique locking needs due to their heavier frames and integrated electronics. This guide reviews the top ebike locks available in 2026, including those designed to resist even angle grinder attacks.
Why Ebike Security Matters
Ebikes are increasingly targeted by thieves because of their value. While some look like ordinary bikes, their components and motors make them more expensive to replace. Traditional bike locks may not be sufficient against determined thieves using power tools. Choosing the right lock is not just about deterring casual theft; it’s about protecting a substantial financial asset.
Best Grinder-Resistant Lock: Abus Granit Super Extreme 2500
The Abus Granit Super Extreme 2500 ($330) stands out as one of the most formidable U-locks on the market. Its intimidating design and heavy-duty construction deter casual thieves, while the tungsten carbide-coated shackle offers exceptional resistance to cutting tools. The lock’s dimensions (9.16″ x 4″) accommodate most ebike frames, including those with thicker tubes or unusual shapes.
While no lock is entirely foolproof, the Granit Super Extreme has proven difficult to defeat even in controlled testing. Abus also provides a well-designed mounting bracket, making it easier to carry the 5.03-pound lock without significant inconvenience.
Best Ultra-Secure Bike Lock: Kryptonite New York Diamond
Kryptonite’s New York Diamond Bike U-Lock ($350) is an iconic choice for serious security. Certified with a Powered Cycle Diamond rating, it is among the few locks that have met the highest standards for grinder resistance. The 1-inch double-layer steel shackle, coated with diamond-hard material, forces thieves to burn through multiple discs.
The lock weighs 5.07 pounds, making it best suited for high-value ebikes where weight is less of a concern. Kryptonite also offers a five-year anti-theft warranty of up to $5,000 if registered and used correctly.
Best Secondary Lock: Ottolock Cinch
To protect wheels or additional components, a secondary lock is recommended. The Ottolock Cinch ($61) is a lightweight and flexible option, ideal for quick stops where removing a wheel is a risk. Its Kevlar-reinforced steel cable and plastic outer layer prevent scratches on bike frames. The combination lock format eliminates the need for carrying extra keys.
A Cheaper Grinder-Resistant Bike Lock: Litelok X1
The Litelok X1 ($200) offers a balance of security and versatility. Constructed with high-strength ceramic composite material, it’s designed to withstand grinder attacks for significantly longer than traditional U-locks. The anti-rotation locking system requires cutting through both sides, making it more difficult to defeat. At 3.7 pounds, it’s lighter than some high-security alternatives.
Lightest, Smallest Grinder-Resistant Lock: OnGuard RockSolid U-Lock
The OnGuard RockSolid U-Lock ($221) is the lightest grinder-resistant option tested, weighing just 3 pounds. While not as heavily vetted as top-tier locks, it has proven effective in informal tests against angle grinders. Its compact size makes it easier to carry, and the lifetime warranty provides added peace of mind.
Best Folding Bike Lock: Abus Bordo Granit 6500K
The Abus Bordo Granit 6500K ($185) is ideal for locking larger ebikes, including cargo models, or multiple bikes simultaneously. Its folding design allows for compact storage when not in use. The 3.68-pound lock is secure and easy to deploy with its included key.
Best Wearable Bike Lock: Hiplok Gold
The Hiplok Gold ($160) offers a unique approach to lock transport. The 5-pound chain integrates a strap, allowing it to be worn as a belt or fannypack. This eliminates the need for mounts or bags while providing Pedal Cycle Gold-level security.
Conclusion
Protecting your ebike requires a strategic approach. From heavy-duty U-locks like the Abus Granit Super Extreme to versatile folding locks like the Abus Bordo, the market offers solutions for every rider’s needs. Pairing a primary lock with a secondary option, such as the Ottolock Cinch, further enhances security. Investing in a quality lock is a small price to pay for the peace of mind knowing your ebike is well-protected.
