1. Best Overall Lock for E-Bikes: Kryptonite Evolution Mini-7 U-Lock with Cable

Key Specifications:

• 13mm hardened steel U-lock shackle + 4ft x 10mm security cable
• Disc-style cylinder with dust cover (pick and drill resistant)
• Dimensions: 3.25″ x 7″ interior lock space
• Weight: 3.55 lbs
• Comes with 3 keys and FlexFrame mount

When we tested the Kryptonite Evolution Mini-7, it immediately stood out as the most well-rounded e-bike lock for everyday riders. 

It’s built like a tank with a thick 13mm shackle that shrugs off bolt cutters, and the included 4ft cable makes it easy to secure your rear wheel or accessories.

What really made this one our “best overall” was the balance of protection, portability, and thoughtful extras. 

The side keyway with a sliding dust cover keeps the elements out, and the mount works well on most e-bike frames. It’s not too bulky but still gives you confidence when parking in public.

It also qualifies for Kryptonite’s Anti-Theft Protection program, which gives some peace of mind, up to $2,500 in coverage if registered. That’s a big bonus, especially for higher-end electric bikes.

The only thing to note? The lock is heavy compared to basic U-locks, and it’s not quite long enough to secure both wheels without using the cable. But for most city riders, this combo does the trick.

Pros:

• Strong resistance to cutting and leverage attacks
• Cable included for extra wheel/frame security
• Secure side keyway with dust cover
• Mounting bracket included for easy transport

Cons:

• A bit on the heavy side
• U-lock length may feel limiting for some frame/wheel combos

2. Best Budget E-Bike Lock: Sportneer U-Lock with 6ft Steel Cable

Key Specifications:

• 18mm thick shackle with zinc alloy lock core
• 6ft steel cable included
• Dimensions: 11.5″ x 6.25″
• Weight: 2.5 lbs
• Comes with 2 keys and a mounting bracket

When we tested the Sportneer lock, we honestly didn’t expect it to punch this far above its price point. At under $30, it feels surprisingly solid, and the 18mm thickness gives you decent resistance against basic theft tools.

The included 6ft cable was long enough to lock both wheels or secure to a post, which came in handy during real-world errands. 

The U-lock itself feels tough, and the silicone coating protects your e-bike’s frame from scratches. You also get a mounting bracket, which isn’t perfect but gets the job done.

That said, it’s not meant for high-theft areas. If you’re locking up overnight or in cities known for bike theft, this might not be the best standalone solution.

But for low- to moderate-risk situations, it’s a steal, literally the best e-bike lock for budget-conscious riders.

Pros:

• Great value for the price
• Thick and rugged feel for a budget lock
• Long 6ft cable for versatile locking
• Protective silicone coating

Cons:

• Not rated for high-theft areas
• Mounting bracket could be sturdier

3. Best Heavy-Duty Lock for High-Theft Areas: Kryptonite New York Long Shackle U-Lock

Key Specifications:

• 16mm hardened steel shackle
• Dimensions: 4″ x 10.25″ interior locking space
• Weighs 4.85 lbs
• Double deadbolt locking system
• Rated 9/10 on Kryptonite’s security scale

If your electric bike is worth thousands and you park it in a high-risk area, this is the lock we trust. The Kryptonite New York U-lock is a beast, both in size and in strength. 

When we tested it, it was clear this thing is designed for one job: stop theft.

The 16mm shackle resists bolt cutters, twist attacks, and most handheld tools. It uses a double deadbolt system and a high-security disc-style cylinder to further beef up resistance to tampering. 

It’s also eligible for up to $4,000 in Anti-Theft Protection if registered, which is the highest in Kryptonite’s lineup.

Downsides? It’s heavy. Nearly 5 lbs, to be exact. And it’s more than most people want to carry every day. 

But for long-term locking or high-theft areas like college campuses or downtown parking, this is one of the best locks for electric bikes you can buy.

Pros:

• Extremely strong and secure
• High rating on Kryptonite’s security scale
• Includes key-safe program and theft protection
• Extra-long shackle gives flexibility

Cons:

• Very heavy to carry
• Overkill for low-risk areas

4. Best Value Lock & Cable Combo: NDakter U-Lock with 6FT Cable

Key Specifications:

• 18mm U-lock shackle + 6ft steel cable
• Double deadbolt locking mechanism
• Lock cylinder made of zinc alloy with dust cover
• Weighs 1.54 kg (~3.4 lbs)
• Comes with 3 keys (no bracket included)

When we were testing mid-range locks, the NDakter stood out for giving you a lot of lock for the money. You get a thick 18mm shackle, a 6-foot cable, and a lock core that resists common tampering methods like prying or drilling.

The cable is long enough to secure both wheels or even multiple bikes. That made it handy for group rides or locking up to bulkier fixtures. 

We also liked the ergonomic lock shape and the smooth key operation, no sticking or jamming during testing.

It’s missing a frame mount, which might be a dealbreaker if you’re someone who rides light. 

But if you don’t mind tossing it into a pannier or bag, this is a solid pick for e-bike owners who want balanced security and convenience without overspending.

Pros:

• Tough and reliable for the price
• Cable adds extra locking options
• Smooth, easy-to-use key system
• More interior space than many U-locks

Cons:

• Doesn’t come with a mounting bracket
• Slightly bulky for minimal setups

5. Best Chain Lock for E-Bikes: Kryptonite Keeper 712 Chain Lock

Key Specifications:

• 7mm four-sided hardened steel chain links
• 47.3″ (120cm) total length
• Weather-resistant nylon sleeve and rubber coating
• High-security disc-style cylinder
• Weighs 3.75 lbs

If you prefer the flexibility of a chain lock over a rigid U-lock, the Kryptonite Keeper 712 is a solid pick. We tested it on a variety of e-bike frames, and the 4-foot length was long enough to wrap around poles, racks, and even fence posts without a fuss.

The 7mm links aren’t as beefy as high-end motorcycle chains, but they’re enough to deter casual thieves. 

What stood out was the protective nylon sleeve; it prevented scratches and held up well in rain and grit. It also includes a disc-style cylinder that feels more secure than most chain locks in this price range.

One thing to note: Kryptonite rates it as moderate (5/10) security, so it’s best for quick stops or lower-risk areas. 

Still, the flexibility and quality make it one of the best electric bike chain locks if you want more locking options.

Pros:

• Flexible design wraps around almost anything
• Durable, weather-resistant construction
• Easy to use and carry in a backpack
• Good balance of weight and protection

Cons:

• Not ideal for high-theft zones
• Slightly slower to lock than U-locks

6. Best Folding Lock for E-Bikes: Seatylock FoldyLock Compact

Key Specifications:

• Opens to 33.5″ circumference
• Hardened steel with anti-tamper rivets
• Ultra-compact and lightweight
• Includes 2 keys and a silent frame mount
• Winner of the 2020 European Design Award

We were really impressed by the Seatylock FoldyLock when we tested it on the go. It’s the perfect balance of compact design and solid protection. 

The folding rivet system opens up like a ruler, making it flexible enough to wrap around racks and poles, while packing down small enough to disappear into the included mount, no rattle, no bulk.

Despite its small size, it’s no toy. The hardened steel plates and protected rivets feel surprisingly sturdy. It’s quiet on the frame, quick to deploy, and ideal for riders who want a low-profile but secure solution.

This isn’t the lock you’d use overnight in a sketchy alley, but for quick city stops and moderate-risk areas, it really nails that sweet spot between portability and peace of mind. 

Easily one of the best folding locks for electric bikes on the market.

Pros:

• Super compact and lightweight
• Mounts silently, no rattle or bounce
• Sturdy design with quality steel and rivets
• Great for urban commuting and quick errands

Cons:

• Locking length is limited
• Not for high-risk theft zones

7. Best Heavy-Duty Budget Lock: Alshaay U-Lock with Steel Cable

Key Specifications:

• 20mm thick shackle, 12-ton hydraulic shear resistant
• Silicone-wrapped exterior to prevent scratches
• Includes 4ft steel cable and mounting bracket
• Dustproof keyhole cover
• Weighs approx. 3 lbs

When we were testing locks in the $30 range, the Alshaay U-lock surprised us. This thing is thick. At 20mm, it’s one of the beefiest shackle sizes we’ve seen at this price. 

Add in the 4ft steel cable and the heavy-duty mount, and you’ve got a lock that looks and feels like it belongs on a more expensive list.

It also stands out for thoughtful design. The screws are hidden inside the silicone wrap, which looks clean and keeps tampering down. 

The keyhole cover works well, and the lock opens smoothly with no jams.

The only real drawback? It’s bulky. If you prefer minimalist setups, this might feel like overkill. 

But for the money, it’s a smart choice for electric bike riders who want heavy-duty protection without stretching the budget.

Pros:

• Extremely thick and durable shackle
• Cable included for extra flexibility
• Well-designed with hidden screws and protective cover
• Good value for heavy-duty protection

Cons:

• Bulky and heavier than other budget locks
• Mount may require careful positioning

What Type of Lock is Best for an E-Bike?

A U-lock with a thick shackle and a steel cable is generally the best type of lock for an e-bike. It offers strong resistance against cutting and leverage while giving you flexibility to secure both the frame and wheels.

Electric bikes are heavier and more expensive than standard bicycles, which makes them prime targets for theft. 

That’s why lock strength matters. U-locks are the most theft-resistant, while cables help protect removable parts. Some riders also prefer folding locks or heavy chains for added reach or flexibility.

Smart locks with GPS and alarms are becoming more popular too, but they often serve best as a second line of defense, not a replacement for a solid U-lock.

U-Lock vs. Chain vs. Folding vs. Smart Locks

U-locks are the most secure and reliable choice for e-bike owners, while chains and folding locks offer more flexibility and reach. Smart locks add convenience and GPS features but often need to be paired with a physical lock for full protection.

How to Choose the Best E-Bike Lock

Picking the right lock for your electric bike depends on more than just price. You want something that fits your riding routine, security needs, and frame style. 

Here are the key things to consider when choosing the best e-bike lock:

Security Rating & Material

The best e-bike locks are made of hardened steel and resist cutting, drilling, or leverage attacks. Look for locks with a security rating from independent sources like Sold Secure or ART. 

A thicker shackle (13mm or more) typically means stronger resistance to bolt cutters.

Electric bikes cost more than traditional bikes, so you’ll want a lock with high-theft resistance, especially if you leave it in public places.

Locking Mechanism

There are a few types to choose from: key locks, combination locks, and smart locks with Bluetooth or GPS. 

Keyed locks are the most secure, but make sure the cylinder is pick-resistant. Combo locks are convenient, but often easier to break into.

Smart locks add GPS tracking and alarms, which help you locate your e-bike or scare off thieves. These work best when combined with a physical lock like a U-lock or heavy chain.

Portability & Mounting

A good e-bike lock should be easy to carry or mount. U-locks often come with frame brackets, while chains and folding locks can fit in bags or wrap around your seatpost.

Just make sure the lock doesn’t bounce or rattle on the frame; over time, that can damage your paint or get annoying during longer rides.

Length & Fit

E-bikes are heavier and bulkier than regular bikes. You need a lock that can reach around your frame and a fixed object, like a post or rack. 

U-locks with a cable give more flexibility, while folding locks offer decent range in a compact form.

If you often lock up in awkward spots, a longer chain or flexible folding lock may be the better choice.

Where Should You Lock Your E-Bike?

You should lock your e-bike to a fixed, immovable object through the frame and at least one wheel. This makes it much harder for thieves to break or lift the bike away.

Where and how you lock matters just as much as the lock itself. Thieves often look for quick wins, so anything that slows them down works in your favor.

Here are some tips to lock up smart:

• Always lock the frame, not just a wheel or seatpost.
• Use a secondary cable to secure the rear or front wheel if your lock is short.
• Avoid street signs or small trees, which can be lifted or cut.
• Choose high-traffic, well-lit areas where theft attempts are more likely to be noticed.
• Keep the lock off the ground, so thieves can’t smash it with a hammer.
• Angle the keyhole down to make tampering harder.

Can You Use a Regular Bike Lock on an E-Bike?

You can use a regular bike lock on an e-bike, but it may not offer enough security. Most e-bikes are heavier and more valuable, which makes them a bigger target for thieves.

A standard cable lock or basic U-lock might work for a quick coffee stop, but it’s risky for daily commuting or overnight storage. 

E-bikes often come with removable batteries or displays too, so you may need additional protection. 

It’s always better to use a high-security U-lock or heavy-duty chain that’s rated for e-bike theft protection.

Final Words

Keeping your e-bike safe starts with the right lock and smart locking habits. 

U-locks are the go-to choice for strength, but folding and chain locks have their place too, especially if you need more flexibility or compact storage.

If you ride daily in an urban area with higher theft risk, go for something like the Kryptonite New York U-Lock. It’s heavy, but the protection is worth it.

If you’re on a tighter budget or just need something for occasional errands, the Sportneer U-Lock with cable gives solid protection without draining your wallet.

Choose what fits your bike, your route, and your comfort level, and always lock like you mean it.

FAQs

What’s the best lock for an expensive e-bike?

A high-security U-lock like the Kryptonite New York or a heavy-duty chain lock is best for expensive e-bikes. These offer strong protection against bolt cutters, leverage attacks, and picking.

Are folding locks good for e-bikes?

Folding locks are a good option for portability and flexibility. They’re best for quick stops or moderate-risk areas, but may not be as secure as U-locks in high-theft zones.

How do I prevent my e-bike battery from being stolen?

Always remove the battery if possible when locking your e-bike in public. If the battery is fixed, use a secondary cable lock to secure it to the frame or park in monitored areas.

Can a lock really stop professional thieves?

No lock is 100% theft-proof, but high-quality locks can slow down or deter most thieves. The goal is to make your e-bike harder to steal than the one next to it.

Should I use two locks on my e-bike?

Yes, using two different types of locks (like a U-lock and a cable or chain) can improve security. It forces thieves to carry more tools and take more time, which reduces your risk.
