Best E-Bike Lock (2026): Most Secure U-Locks, Chains and Folding Locks

As an Amazon Associate, Gearaffiti earns from qualifying purchases. We did not test these locks in person; this guide is based on maker specifications, independent security ratings, published tests and owner feedback.

An e-bike can cost as much as a used car, and thieves know it. Electric bikes are heavy, so they are rarely carried away in a hurry, but a determined thief with bolt cutters or a battery-powered angle grinder can get through a cheap lock in seconds. The right lock will not make your bike impossible to steal, but it can make it the hardest bike on the rack, which is usually enough for a thief to move on.

This guide compares the best e-bike locks, explains independent security ratings, and shows how to lock an e-bike properly.

Quick Picks

• Best overall: Kryptonite New York Fahgettaboudit Mini
• Best lighter U-lock: ABUS Granit X-Plus 540
• Best angle-grinder resistant: Hiplok D1000
• Best grinder-resistant value: Litelok X1
• Best folding lock: ABUS Bordo Granit X-Plus 6500
• Best chain for home and long stops: Kryptonite New York Fahgettaboudit Chain

Understanding Lock Security Ratings

Brand ratings like “10/10” or “level 15” are useful only for comparing locks from the same maker. Independent ratings are more reliable. The most widely used is Sold Secure, a UK testing body that rates locks Bronze, Silver, Gold and Diamond for pedal cycles, and has separate ratings for powered cycles. Diamond is the highest pedal cycle rating. For an expensive e-bike, aim for Gold at minimum and Diamond if you park in busy cities.

The newest category is angle-grinder resistant locks. Battery grinders can cut through most traditional U-locks, so a few makers now use special materials that slow grinders down dramatically. These locks cost more but are the best protection for high-value bikes in high-theft areas.

1. Kryptonite New York Fahgettaboudit Mini

Best overall. The Fahgettaboudit Mini is one of the most trusted high-security U-locks on the market, and Cyclingnews names it the best overall e-bike lock. It uses a thick 18mm hardened steel shackle and a compact shape that leaves little room for leverage attacks. Retailers list it at around 4.5 pounds, so it is heavy, but it is one of the toughest conventional U-locks you can buy.

Pros: very thick shackle, compact shape resists leverage, proven brand.
Cons: heavy; small shackle can be hard to fit around thick posts and e-bike frames.

2. ABUS Granit X-Plus 540

Best lighter U-lock. ABUS’s Granit X-Plus 540 is a favourite of commuters who want high security without the weight of the Kryptonite. Retailer specifications list a 13mm hardened steel shackle, a weight of around 3.3 pounds, a Sold Secure Pedal Cycle Diamond rating and a powered cycle Gold rating. Its X-Plus disc cylinder is highly resistant to picking and drilling, and it comes with a frame mounting bracket.

Pros: excellent security for its weight, frame bracket, high-quality cylinder.
Cons: thinner shackle than the Fahgettaboudit; pricier than basic U-locks.

3. Hiplok D1000

Best angle-grinder resistant. The Hiplok D1000 is built specifically to resist battery angle grinders, the tool behind many modern bike thefts. It carries a Sold Secure Diamond rating and uses a special composite material in the shackle that clogs and wears cutting discs. It is expensive, but for an e-bike worth thousands parked daily in a city, it offers a level of protection standard locks cannot match.

Pros: resists angle grinders, Diamond rated, strong deterrent.
Cons: high price; heavier than standard U-locks.

4. Litelok X1

Best grinder-resistant value. The Litelok X1 is another angle-grinder resistant U-lock, at a lower price than the Hiplok. TheBestBikeLock.com’s testing found it took more than four times as long to cut through one side of the X1 as the Kryptonite Fahgettaboudit, and notes it is only slightly more expensive than the ABUS Granit X-Plus 540 while costing about half as much as the Hiplok D1000. Bikerumor lists it with a Sold Secure Diamond rating.

Pros: strong grinder resistance for the price, practical size, frame mount.
Cons: still costs more than conventional U-locks.

5. ABUS Bordo Granit X-Plus 6500

Best folding lock. Folding locks fold into a compact block that mounts on the frame, then open into a long, flexible shape that reaches around posts more easily than a U-lock. The Bordo Granit X-Plus 6500 is one of the most secure folding locks available, with a Sold Secure Gold rating. It is a good choice for shorter stops and lower-risk areas, or as a second lock alongside a U-lock.

Pros: easy to carry, flexible shape, good security for a folding lock.
Cons: not as strong as Diamond-rated U-locks.

6. Kryptonite New York Fahgettaboudit Chain

Best chain for home and long stops. Kryptonite’s Fahgettaboudit chains use thick hardened links and a separate disc lock. Bikerumor lists the 1410 chain at a Sold Secure Diamond rating. Chains are too heavy for daily carrying, but they are ideal for locking e-bikes at home, in a garage, or at a workplace where you can leave the lock in place, and they wrap around large objects that U-locks cannot reach.

Pros: very strong, reaches big posts, can secure multiple bikes.
Cons: very heavy; best left at a fixed location.

U-Lock vs Chain vs Folding Lock

U-locks offer the best security for their weight and are the first choice for most riders. Pick a size that fits around your frame and common bike racks.

Chains are flexible and reach awkward objects, but heavy chains are hard to carry. Use them at home or work.

Folding locks are compact and easy to mount on the bike, but generally less secure than top U-locks.

How to Lock an E-Bike Properly

1. Lock the frame: always pass the lock through the frame, not just a wheel, and around a solid, fixed object.
2. Use two locks: combine two different types, such as a U-lock and a chain or folding lock. Thieves usually carry one type of tool.
3. Remove the battery and display: batteries are expensive and easy to resell. Take them with you if they are removable.
4. Fill the lock: position the lock so there is little empty space inside, leaving no room for jacks or bars.
5. Keep the lock off the ground: a lock resting on the ground is easier to smash or cut.
6. Park smart: choose busy, well-lit, camera-covered spots, and never leave an e-bike locked outside overnight.
7. Register and record: note your bike’s serial number, take photos, and register it with a bike registry and your insurer.

Extra Ways to Protect Your E-Bike

• GPS tracker: a hidden tracker can help police recover a stolen bike. See bike trackers.
• Alarm: some locks and add-on devices sound a loud alarm when disturbed.
• Locking skewers: security skewers or bolts make wheels and seats harder to steal.
• Insurance: check whether your home or renters insurance covers your e-bike, or buy dedicated bike insurance.

Budget Option: OnGuard Brute

If the top locks are beyond your budget, OnGuard’s Brute U-lock is a common recommendation for good security at a lower price. It uses a thick hardened steel shackle and a sturdy locking mechanism. It is not angle-grinder resistant, so pair it with smart parking habits and a second lock in higher-risk areas. See the OnGuard Brute.

Choosing the Right Lock Size

E-bikes often have thicker frame tubes, larger batteries and wider tyres than regular bikes, so a small U-lock may not fit. Measure the thickest part of your frame where you plan to lock it, then add the width of a typical bike rack or post. Compact “mini” U-locks are more secure because they leave less room for tools, but they can be hard to use on fat-tyre or step-through e-bikes. If you ride a fat-tyre bike like those in our guide to the best fat bikes under $2,000, a standard-size U-lock or a chain may be easier.

Where E-Bikes Are Most Often Stolen

• Outside homes and apartment buildings: bikes left on porches, in shared hallways or in communal bike rooms are frequent targets.
• Train stations and transit hubs: long, predictable parking times give thieves time to work.
• Quiet streets at night: fewer witnesses make it easier to use noisy tools.
• Garages and sheds: without an anchor point, a bike inside a garage can still be taken if the door is forced.

For home storage, consider a ground or wall anchor bolted into concrete or a stud, and lock the bike to it with a heavy chain. Keep garage doors closed and bikes out of view from the street.

Lock Care and Maintenance

A lock that is hard to open is a lock you stop using. Spray a little dry lubricant into the keyway every few months, especially after riding in rain or salty winter conditions. Keep spare keys somewhere safe at home, and register your key number with the maker if they offer a replacement service. Check mounting brackets regularly so the lock does not rattle loose on rough roads.

What To Do If Your E-Bike Is Stolen

1. Report it to the police right away and get a report number. Insurers usually require it.
2. Share the serial number and photos with bike registries and local cycling groups, and post on community social media pages.
3. Check resale sites such as online marketplaces for listings that match your bike, and alert police rather than confronting a seller yourself.
4. Use your tracker if you have one, and pass the location to police.
5. Contact your insurer with your report number, receipts and photos.

Many locks, including some Kryptonite models, come with an anti-theft protection offer that may contribute toward a replacement if a bike is stolen because the lock was defeated. Register the lock with the maker soon after buying it, and read the terms, since coverage is often limited to certain regions and conditions.

Frequently Asked Questions

What lock rating do I need for an e-bike?

For most e-bikes, choose at least a Sold Secure Gold lock, and Diamond if you park in a city or leave the bike for long periods.

Can an angle grinder cut through any bike lock?

Given enough time, yes. Angle-grinder resistant locks like the Hiplok D1000 and Litelok X1 slow thieves down significantly, often enough to make them give up.

Is a heavy lock really necessary?

Generally, heavier locks with thicker shackles are harder to cut. Mount the lock on the frame so the weight is easier to live with.

Should I use two locks?

Yes, if you can. Two different lock types force a thief to carry two kinds of tools and spend more time.

Do I need a special lock for an electric scooter?

Many of the same locks work for scooters. Check the shackle size fits around the scooter’s stem or deck. See our guide to electric scooters for heavy adults for larger scooters that benefit from strong locks.

How much should I spend on an e-bike lock?

A common rule of thumb is to spend around 10% of your bike’s value on security. For a $1,500 e-bike, that means a lock or lock combination around $150, which buys a Diamond-rated U-lock or a good U-lock plus a second lock.

Are combination locks safe for e-bikes?

Most combination locks offer lower security than good keyed locks. They are fine for very short stops in low-risk places, but use a keyed Gold or Diamond-rated lock for regular parking.

Final Verdict

The Kryptonite New York Fahgettaboudit Mini is our top pick for most e-bike owners. Choose the ABUS Granit X-Plus 540 for a lighter Diamond-rated U-lock, the Hiplok D1000 or Litelok X1 for angle-grinder resistance, the ABUS Bordo 6500 for a compact folding lock, and a Fahgettaboudit chain for home or workplace parking. Pair a good lock with smart parking habits and your e-bike will be a much less tempting target.
