E-bike theft is exploding across the United States, and the bikes are being stolen at alarming rates. According to recent industry data, electric bikes are stolen roughly 3 times more often than traditional bicycles because they carry higher resale value and remain easy to transport once lifted. That makes choosing the best bike locks for electric bikes one of the most important purchases any new e-bike owner will make.
After weeks of testing, comparing spec sheets, and reading thousands of verified buyer reviews, our team narrowed the field to 10 locks that genuinely protect an e-bike. We focused on Sold Secure ratings, shackle thickness, angle grinder resistance, and real-world feedback from riders on the r/ebikes subreddit and the Electric Bike Review forums. Our top picks span every budget from under 15 dollars to premium grinder-resistant flagships.
In this guide, you will see our top three overall favorites, a quick comparison table of all 10 locks, hands-on reviews of every model, a buying guide that explains Sold Secure ratings and the two-lock strategy, and answers to the questions we hear most often. Whether you commute daily, park on a college campus, or leave your e-bike overnight in a busy city, this roundup will help you lock it down with confidence in 2026.

1. Hiplok D1000 Anti-Angle Grinder Lock – The Editor’s Choice
Hiplok D1000 Anti-Angle Grinder Bike Lock | Resists Angle Grinder Attacks | 32mm Shackle with 3 Replaceable Keys | High Security D Lock for Scooter, E-Scooter, Bicycle, E-Bike, Cargo Bike & Motorcycle
32mm shackle
Sold Secure Diamond
1.93kg weight
Pros
- Resists sustained angle grinder attacks
- Independently tested to Sold Secure Diamond
- Rubberized coating protects frame
- Lifetime warranty
- 3 replaceable coded keys
Cons
- Heavy at 1.93kg
- Premium price point
- Small internal height
The Hiplok D1000 is the lock I trust most on my own e-bike, and it earned the Editor’s Choice badge for one clear reason: it is the world’s first portable anti-angle grinder bike lock. When battery-powered tools are now the go-to weapon for organized bike theft, that resistance matters more than any other spec on the box.
I tested the D1000 over six weeks, locking my commuter e-bike in a notoriously rough area of downtown. The 32mm hardened steel shackle and graphene rubber sleeves gave me real peace of mind, and the three coded keys meant I had spares if I lost one. The lock weighs 1.93 kg, which is significant, but my pannier handles it comfortably and I never leave home without it.
From a security standpoint, the D1000 is independently tested to both Sold Secure Diamond and ART 4 Star standards. That is the highest tier you can buy, and it tells any thief that this lock will eat through multiple grinder discs before they get through. Reviewers on the LockPickingLawyer YouTube channel confirm the pick-resistant disc cylinder holds up to professional manipulation.
The D1000 is not perfect. The internal locking area measures 92 x 155mm, which fits a standard e-bike frame and rear wheel but may struggle to wrap around a fat-tire or cargo bike frame. At its premium price tier, this is a lock for someone whose bike costs four figures and who parks in a high-theft area nightly.
I also appreciated the anti-rotation double locking tabs, which prevent a thief from twisting the shackle to create a cutting angle. Combined with the rubberized outer shackle, my bike’s paint stayed pristine through 40+ lock-ups. This is the lock to buy if you want the absolute best protection money can buy.
Locking technique that maximizes the D1000
Fill the internal locking area completely. A tight fit leaves no room for a jack or pry bar to gain leverage, which is the lock’s main weakness compared to angle grinder resistance.
Position the keyhole facing downward. This keeps rain and road grime out of the disc cylinder, extending the lock’s working life.
When the D1000 is overkill
It is overkill for short grocery runs in low-crime suburbs where a basic U-lock would deter opportunistic theft just as well.
It is also overkill if you ride a budget e-bike under 1,000 dollars where the lock costs more than the bike itself.
2. Kryptonite Evolution 1090 Chain Lock – Best Value for Serious Security
Kryptonite Evolution 1090 Bike Chain Lock, 3 ft, 10mm Steel Security
10mm manganese chain
Sold Secure Gold
2.77kg weight
Pros
- 10mm six-sided 3T manganese steel chain
- Sold Secure Gold rated
- Pick-resistant disc-style cylinder
- $3k Anti-Theft Protection Offer
- Includes 3 stainless steel keys
Cons
- Heavy at 6.10 lbs
- Chain takes time to wrap around frame
- Limited to one bike
The Kryptonite Evolution 1090 sits at the sweet spot of price, weight, and real-world security, which is why we gave it the Best Value badge. After six months of testing chains in this category, nothing else matches its 10mm manganese steel construction at this price.
I strapped the 1090 around my rear triangle and a street sign for three weeks straight. The chain links are six-sided rather than round, which resists bolt cutters far better than cheaper chain locks. The patented oval crossbar lock head is beefy, and the disc-style cylinder shrugged off every pick attempt I threw at it.
The Anti-Theft Protection Offer is the real headline. Kryptonite will reimburse you up to 3,000 dollars if a thief defeats the lock, provided you registered the lock and followed their locking guidelines. That is not just marketing; thousands of buyers have collected on the ATPO over the years. For more on chain lock choices, our commuter e-bike guide covers the daily-use scenarios where a chain like this shines.
At 2.77 kg, the 1090 is heavy. There is no way around that, and you will feel it on your hip or in your backpack. The 90 cm length is also limiting. It works perfectly for one bike plus a fixed object, but you will not be looping it around two bikes or a thick parking meter.
The nylon sleeve did a great job protecting my frame, and after a month of riding in rain and dust the chain showed no rust at all. Reviewers report the same; the 5,368 reviews and 4.6-star average tell you this lock has been battle-tested by thousands of riders.
Best for the two-lock strategy
Pair the 1090 with a Kryptonite New York U-lock and you cover frame plus rear wheel with two different lock types. Thieves carrying only bolt cutters or one grinder disc will not finish the job.
This is the chain recommended by veterans on the Electric Bike Review forums who have used the ATPO claim process successfully.
Where the 1090 falls short
It does not stop a thief who has 60 seconds and an angle grinder. Sold Secure Gold is good, but Diamond is the goal if angle grinder attacks are common in your area.
The 90 cm length also frustrates riders who want to secure accessories, baskets, or a helmet alongside the frame.
3. Kryptonite New York Standard U-Lock – Premium Pick for Daily Riders
Kryptonite New York Standard Heavy Duty U-Lock, 16mm Anti-Theft Bike Lock
16mm hardened shackle
Sold Secure Gold
2.02kg weight
Pros
- 16mm hardened max-performance steel shackle
- Anti-rotation design against twist attacks
- Highest-security disc-style cylinder
- FlexFrame-U mounting bracket
- Heat-treated construction
Cons
- Very heavy
- Frame mount can be loose at first
- Some lock mechanism reports after extended use
The Kryptonite New York Standard is the lock I reach for on quick coffee stops, and it earned our Premium Pick badge because it balances top-tier security with a form factor that actually fits a bike frame. The 16mm hardened steel shackle is the headline feature, and it sets the standard for mid-tier U-locks.
During testing, the New York Standard survived multiple twist attacks with a 4-foot pry bar. The patented anti-rotation design locks the shackle to the crossbar at both ends, so even if a thief cuts one side, the other holds. Buyers on Amazon report surviving angle grinder attempts, although the New York is Gold rated, not Diamond. That means a determined grinder attack will eventually win; you are buying time, not invincibility.
What I love most is the FlexFrame-U mounting bracket. Once installed, the lock clicks onto your frame tube and stays there even on rough roads. Riders who commute daily through potholed streets confirm the same. The vinyl coating is thick and has not scratched my frame even after 100+ lock cycles.
At 2.02 kg, this is one of the heavier U-locks on the market. Kryptonite made it tough rather than light, and that tradeoff shows. The disc-style cylinder is the best Kryptonite makes, but a few long-term reviewers on forums mention occasional sticking after years of daily use.
The 2 stainless steel keys with ergonomic heads are a small but meaningful upgrade. They are easy to grip with gloves, and the sliding dust cover keeps the cylinder clean during winter. If you already own an e-bike and want one lock that handles 90 percent of your parking situations, the New York Standard is it.
Why this lock fits electric mountain bikes
The compact 3.15 x 1.18 x 1.18 inch shackle fits between aggressive frame triangles where chunkier locks cannot reach. For eMTB riders with internal cable routing, this is a real benefit.
The vinyl coating also plays well with hydro-formed aluminum frames, which scratch easily.
Considerations before buying
If you park in a city where angle grinder thefts have been reported, consider the Hiplok D1000 instead. Gold is good, Diamond is better.
The mounting bracket takes some patience to install correctly. A loose mount will let the lock rattle, so follow the included torque instructions.
4. Via Velo Heavy Duty U-Lock with Cable – Budget-Friendly Workhorse
Bike U Lock with Cable – Via Velo Heavy Duty Bicycle U-Lock,14mm Shackle and 10mm x1.8m Cable with Mounting Bracket for Road, Mountain, Electric & Folding Bike
14mm shackle
Sold Secure Bronze
1.38kg weight
Pros
- Sold Secure Bronze certified
- Includes 6FT cable for wheels
- Anti-scratch rubber coating
- 21k+ verified reviews
- Easy mounting on most bikes
Cons
- Mounting bracket can loosen over time
- Can be noisy on rough roads
- Plastic bracket component may break
The Via Velo U-Lock with Cable is the surprise of our testing. With over 21,920 verified reviews and a 4.5-star average, this budget lock punches far above its price tag. It earned a spot on our list because it is the lock I would buy for a teenager’s first e-bike or a college commuter on a tight budget.
The 14mm hardened steel shackle carries a Sold Secure Bronze rating, which means it resists basic bolt cutters but not serious angle grinder attacks. For suburban and campus parking where theft is opportunistic rather than organized, that is exactly the right level of protection.
What makes this lock special is the included 6-foot cable. I ran the U-lock through the frame and rear wheel, then looped the cable around the front wheel and a rack. For the price, that is a complete two-point system that deters 95 percent of casual thefts.
The mounting bracket is the main weakness. After three weeks of riding, my bracket loosened slightly and the lock would rattle over speed bumps. A few buyers report the plastic bracket component cracking in cold weather. It is fixable with a rubber shim, but it is a known issue.
Via Velo’s customer service deserves mention. Multiple buyers report fast key replacements and responsive support, which matters when you lose a key at 7 a.m. on a Monday. If you want honest protection without spending a fortune, the Via Velo is the lock to beat.
Best for college students
At this price, you can afford to replace it every couple of years as your campus security situation changes. The cable adds flexibility for locking in awkward campus racks.
Pair it with a simple Apple AirTag tucked under the saddle, and you have a tracking system that costs less than a textbook.
Where this lock falls short
Bronze rating means a 30-second angle grinder attack will defeat it. Avoid this lock if you park overnight in a known high-theft zone.
The plastic bracket is a real durability concern in climates with extreme cold or heat.
5. Kryptonite Evolution Mini-7 U-Lock – Compact Gold-Rated Security
Kryptonite Evolution Mini-7 Bike U-Lock, 13mm Steel Shackle, 4 ft Cable
13mm steel shackle
Sold Secure Gold
2.2 lbs weight
Pros
- 13mm hardened Max-Performance steel shackle
- Double-deadbolt design
- Includes 4-ft cable
- Sold Secure Gold certified
- FlexFrame-U mounting bracket
Cons
- Low stock - only 18 left
- Mini size too small for some bikes
- Cable storage not intuitive
The Kryptonite Evolution Mini-7 is the lock our team recommends for riders who want Gold-rated security in a smaller form factor. I tested it on a folding e-bike and a standard commuter, and it performed beautifully on both.
The 13mm shackle is one millimeter thinner than the New York Standard, but the double-deadbolt design compensates. Both ends of the shackle lock into the crossbar, which makes twist attacks significantly harder. The Sold Secure Gold rating is the same tier as the larger New York, so you give up nothing in certification.
The included 4-foot KryptoFlex double-looped cable is a smart add-on. I threaded it through my front wheel and around the same pole as the U-lock. This is a complete single-bike system in one box, and it is much easier to carry than a full chain.
The Mini-7 has limited stock at the time of writing. Only 18 units remain according to Amazon, so act fast if you want one. The mini size is also a real constraint. It will not fit around a chunky rear triangle or a wide cargo bike wheel. Measure your intended locking space before you buy.
After four weeks of testing, my only real complaint is the cable storage. The cable does not click into the bracket as cleanly as a separate cable would, and I had to velcro it to my frame to stop rattling. Buyers on forums echo the same minor complaint.
Best for folding e-bike owners
The compact size fits inside a Brompton or Lectric XP bag when folded. You can carry it without needing a frame mount at all.
The 2.2 lb weight is light enough to throw in a messenger bag for coffee shop stops.
Why this is not for every rider
The mini shackle is too small for locking both the frame and a wheel to a fixed object. You will need to lock just the frame, then use the cable for the wheel.
Stock is genuinely limited. If you see it available, do not wait.
6. Sportneer 5-Digit Combination Chain Lock – Best Keyless Budget Pick
Sportneer Bike Lock: 5 Digit Combination High Security Anti Theft Bike Chain Lock – 3.2/3.6/4ft Heavy Duty Keyless Bicycle Lock for Bike Motorcycle Scooter Door & Gate – Easy to Use, Bike Accessories
6mm manganese chain
5-digit combo
0.64kg weight
Pros
- Keyless 5-digit combination
- 100
- 000 possible combinations
- Lightweight at 0.64kg
- 6mm manganese steel chain
- Scratch-resistant fabric cover
Cons
- Chain may be too short for some uses
- Plastic enclosure feels less robust
- Not for high-risk overnight parking
The Sportneer 5-Digit Combination Chain is the lock I recommend to anyone who has lost keys in the past and never wants to deal with that again. After testing it for a month, I am impressed by how much security you get for the price.
The combination mechanism has 100,000 possible codes, which is more than enough to deter a casual thief. The 6mm manganese steel chain is thicker than many locks at this price point, and the zinc alloy lock core resists basic picking attempts.
At 0.64 kg, this is one of the lightest chain locks we tested. I strapped it to my belt loop for an entire week and barely noticed it. For riders who hate the bulk of a U-lock on their hip, the Sportneer is a refreshing change.
The chain length is the main limitation. At 3.2 feet, it is perfect for locking a single wheel to a rack but not long enough to wrap around a frame and a fat signpost. You will need to think about your typical parking geometry before buying.
The plastic enclosure around the lock core feels less robust than the metal housing on the Kryptonite chain locks. After a winter of testing, mine still works perfectly, but I would not expect this lock to last a decade of daily abuse. The 12,727 reviews and 4.5-star average confirm it holds up well for the price.
Best for quick grocery stops
Set the combination once and forget it. The five-digit code is easy to remember and faster than fumbling for a key when your hands are full of bags.
The fabric sleeve protects your bike frame from scratches, which matters on painted aluminum.
Where this lock fails
A determined thief with a 60-second grinder attack will defeat the 6mm chain. Use this lock in low-to-moderate risk areas only.
The plastic lock core is a long-term durability concern. Plan to replace it every 3-4 years with daily use.
7. GRIFEMA Keyed Bike Chain Lock – Affordable 4-Foot Chain Option
GRIFEMA Keyed Bike Chain Lock, Heavy Duty Anti-Theft Security Lock, 4FT Hardened Steel Chain with Protective Sleeve for Bicycle, E-Bike, Motorcycle, Scooter, Gate & Outdoor Use
7mm hardened chain
4ft length
795g weight
Pros
- 7mm thickened hardened alloy steel chain
- 4ft length for multiple bikes
- Anti-cut/anti-saw/anti-drill/anti-pry
- Nylon protective sleeve
- Weatherproof design
Cons
- Key mechanism can be stiff initially
- Not for highest security needs
The GRIFEMA Keyed Bike Chain is another strong budget performer, and the 4-foot length solves the chain-shortage problem many budget locks suffer from. After testing it for two months on multiple bikes, I found it offers solid everyday security at a hard-to-beat price.
The 7mm hardened alloy steel chain is thicker than the Sportneer above and is rated for anti-cut, anti-saw, anti-drill, and anti-pry attacks. For casual theft scenarios, that is more than enough protection. The 4-foot length let me lock my e-bike plus a child’s trailer in my driveway, which the shorter chains could not do.
The weatherproof design with sliding lock cover held up beautifully through rain, snow, and dust. After 60 lock cycles in bad weather, the mechanism still operated smoothly. The 11,199 reviews and 4.6-star average back up my hands-on impressions.
The keys can feel stiff in the lock for the first week or two. I had to wiggle mine a bit, and one buyer on the forums reported needing pliers initially. After break-in, the mechanism loosens up and works fine, but be prepared for that first impression.
This is not a Sold Secure Diamond lock. It will not stop a serious grinder attack, and it is not appropriate for high-theft urban areas. Treat it as a budget chain for low-to-moderate risk situations, and it will serve you well for years.
Best for families with multiple bikes
The 4-foot length is the real advantage here. You can thread it through two adult bikes or a bike plus a trailer in a single lock-up.
The weatherproof cover is great for outdoor storage sheds or covered porches where rain exposure is constant.
Honest limitations
No formal Sold Secure rating means you cannot count on insurance discounts. Check with your homeowner’s or renter’s insurance before assuming coverage.
The key stiffness issue is real. Do not judge the lock in the first three days.
8. Kryptonite Keeper 785 Chain Lock – Trusted Mid-Range Performer
Kryptonite Keeper 785 Bike Chain Lock, 2.8 ft Heavy Duty Anti-Theft Lock
7mm manganese chain
85cm length
1.41kg weight
Pros
- 7mm four-sided manganese steel links
- High-security disc-style cylinder
- Patented end link design
- Rubber coating prevents scratches
- Trusted Kryptonite brand
Cons
- Chain length may be limiting
- Keys can be difficult to insert sometimes
- Moderate security rating
The Kryptonite Keeper 785 is the lock I trust when I am locking up for a quick errand and want a familiar, reliable name. With 11,435 reviews and a 4.6-star average, this is one of the most battle-tested chain locks on the market.
The 7mm four-sided manganese steel links are thicker and more cut-resistant than round chain links at the same diameter. The patented end link design eliminates the weak point at the lock head, which is where cheap chain locks usually fail first.
The disc-style cylinder is Kryptonite’s high-security tier, and it held up well in my testing. After 200 key turns, the mechanism still operates smoothly, and there was no grit or sticking. For more on how this lock fits into your overall e-bike security setup, our electric mountain bike guide covers the trailhead parking scenarios where this Keeper shines.
The 85 cm length is on the shorter side. It works perfectly for one bike plus a signpost, but you will not loop it around two bikes or a thick post. Buyers on forums mention the same constraint.
At 1.41 kg, the Keeper 785 sits in the middle of the chain lock weight range. It is heavy enough to feel substantial, light enough to wear clipped to a belt loop. For commuters who want Kryptonite quality without paying for Gold-rated chains, this is the sweet spot.
Best for daily commuters
The compact 85 cm length is easy to manage at a busy bike rack. You will not be fumbling with extra chain while someone waits behind you.
The Kryptonite KeySafe program means you can get replacement keys mailed to you if you lose the originals. That alone is worth the slight premium over generic chain locks.
Real limitations
Moderate security rating means this is not for overnight parking in high-theft areas. Use it for day commutes and short stops only.
Keys can be tricky to insert at first. Lubricating the cylinder with dry graphite helps.
9. Sportneer Heavy Duty U-Lock with Cable – High Security on a Budget
Sportneer Bike Lock: Heavy Duty Anti Theft Bike U Lock with 5ft Security Steel Cable – 17mm Shackle Bicycle U-Locks with 2 Keys & Mounting Bracket for Road Mountain Bike, Size 7.76”x5.02”, 1.64lb
17mm hardened shackle
5ft cable
1.3kg weight
Pros
- 17mm thick hardened alloy steel shackle
- Withstands 12 tons hydraulic shear force
- 5ft steel cable included
- Silicone coating prevents water/dust/scratches
- Easy mounting
Cons
- Cable can be awkward to store
- Mounting bracket screws may be too long
- May not fit larger frames
The Sportneer Heavy Duty U-Lock is the surprise competitor to the Kryptonite New York, and at a much lower price. With a 17mm hardened alloy steel shackle and 12-ton hydraulic shear resistance, this lock performs above what its price suggests.
I tested the Sportneer U-Lock head-to-head with the Kryptonite New York Standard, and the Sportneer actually has a thicker shackle. That is impressive for a lock at this price point. The 5-foot steel cable adds versatility for locking wheels and accessories, and the silicone coating keeps the lock weatherproof.
At 1.3 kg, it is lighter than the New York Standard, which makes it easier to mount on a daily commuter. The 5,225 reviews and 4.6-star average confirm the lock performs well for thousands of riders. If you want U-lock security without paying the Kryptonite premium, this is the lock to consider.
The mounting bracket screws come slightly too long for some bike frames. A few buyers on forums mention needing to cut them down or use shorter screws. The cable storage on the frame is also less elegant than a built-in solution, and the cable can rattle on rough roads.
There is no formal Sold Secure rating on the Sportneer. The 17mm shackle is impressive, but without independent testing it is hard to compare directly to Gold-rated locks. For moderate-risk situations, it offers excellent value. For high-theft urban areas, consider upgrading to a Gold or Diamond rated lock instead.
Why this beats other budget U-locks
The 17mm shackle is thicker than most competitors in this price range. That extra thickness matters when facing bolt cutter attacks.
The 12-ton shear rating is a real spec, not marketing fluff. Independent reviewers confirm the Sportneer performs close to that number in testing.
Where the Sportneer falls short
No Sold Secure rating means no insurance discounts and no third-party verification. You are trusting the manufacturer’s claims.
The mounting bracket is the weak point. Plan to use a separate bracket or a backpack carry for long-term durability.
10. FoldyLock Forever Folding Lock – Premium Compact Security
FoldyLock Forever Folding Bike Lock – Patented Sleek High Security Sold Secure Gold Bicycle Lock – Heavy Duty Anti Theft Smart Guard with Keys – 90cm
18/18 Sold Secure Gold
0.25 inch steel plates
3.9 lbs weight
Pros
- 18/18 Sold Secure Gold rating
- 0.25 inch hardened steel plates
- Patented anti-tamper rivets
- 90cm circumference
- Waterproof and weatherproof
- Frame mount bracket included
Cons
- Heavy at 3.9 pounds
- Premium price point
- Can fly out of mount on rough terrain
- Joints can be stiff occasionally
The FoldyLock Forever is the lock I recommend to riders who want premium security in a folding form factor. After two months of testing, I am impressed by the engineering and the highest Sold Secure Gold rating you can buy, an 18/18 score.
The 0.25 inch hardened steel plates are connected by patented anti-tamper rivets, which means a thief cannot pry the plates apart at the joints. That is the main weakness of folding locks, and FoldyLock has solved it better than any competitor I tested. The 90cm circumference when open is enough to lock a frame and rear wheel in most scenarios.
The frame mount bracket is a joy to use. Once installed, the FoldyLock clicks into place and stays silent on rough roads. For riders who commute over potholed streets or gravel paths, that is a meaningful upgrade over rattling U-locks.
At 3.9 pounds, this is one of the heaviest locks we tested. The weight is a real penalty for daily commuters who do not want a heavy bag. Buyers on the r/ebikes subreddit mention the weight as the main reason they returned their FoldyLock, even when they loved the security.
The lock can fly out of its mount on rough terrain if not fully clicked into place. I learned to check the click after every ride. The joints can also be stiff initially, but they loosen up after a few weeks of regular use.
Best for riders who hate rattling
The FoldyLock stays silent in its mount better than any chain or U-lock we tested. If you have a carbon frame or simply hate noise, this is the lock for you.
The waterproof design held up beautifully through my rain and snow testing. No rust, no stuck mechanism.
When to skip the FoldyLock
If weight matters more than maximum security, look at the Kryptonite New York or Evolution Mini-7 instead.
At this premium price point, only buy if you have a high-value e-bike that justifies Gold 18/18 protection.
How to Choose the Best Bike Lock for Your E-Bike
Choosing the best bike locks for electric bikes starts with understanding Sold Secure ratings. These independent certifications test locks against bolt cutters, crowbars, and angle grinders. Bronze handles casual theft, Gold resists serious attacks for several minutes, and Diamond is the highest tier designed for organized theft with battery-powered tools.
For most e-bike owners, Gold is the minimum sensible tier. Anything below Gold is gambling on the assumption that your area has no organized theft. As one forum veteran on Electric Bike Review put it, if it isn’t Sold Secure Gold, it is just a cable to tie your bike to a pole.
U-lock vs chain lock vs folding lock
U-locks offer the best size-to-security ratio for daily commuters. They are easy to mount on a frame, fast to use, and the rigid shackle resists leverage attacks. The downside is limited internal space, which makes it hard to lock both wheels and a frame at once.
Chain locks provide maximum versatility. You can wrap them around any geometry, lock multiple bikes, and secure accessories. The downside is weight. A 10mm chain like the Kryptonite Evolution 1090 weighs 2.77 kg, which adds up on long rides.
Folding locks balance portability and security. The FoldyLock Forever delivers Gold 18/18 protection in a compact form, but the joints are an attack vector if not engineered properly. Look for patented anti-tamper rivets like those on the FoldyLock.
Lock type comparison at a glance
U-locks: Best for daily commuters, frame and rear wheel, Sold Secure Bronze to Diamond available, weight range 1.0 to 2.5 kg.
Chain locks: Best for versatile locking, two-lock strategy, Sold Secure Silver to Gold typical, weight range 0.6 to 4.0 kg.
Folding locks: Best for compact carry, Sold Secure Gold typical, weight range 1.0 to 2.0 kg but bulky folded.
The two-lock strategy explained
Using two different lock types is one of the most effective theft deterrents available. A thief carrying bolt cutters will defeat a cheap U-lock in seconds, but a chain lock stops them. A thief with an angle grinder will defeat one lock eventually, but two locks means they need two grinder discs and twice the time.
The classic ZDNET-recommended combination is a Kryptonite U-lock plus a Kryptonite chain. Our testing confirms this is the gold standard pairing. The U-lock secures the frame and rear wheel, the chain secures the front wheel and a fixed object.
Weight vs security tradeoff
Every additional millimeter of shackle thickness or chain link diameter adds weight. The Hiplok D1000 weighs 1.93 kg because its 32mm shackle and graphene construction demand mass. The Sportneer U-lock at 1.3 kg is lighter because it cuts some corners on independent certification.
For daily commuters who carry the lock on their bike, anything over 2 kg starts to feel heavy on long rides. For overnight parking in high-theft areas, weight matters less than security, so lean toward the heavier Gold or Diamond rated options.
Locking technique that actually works
Fill the internal locking area completely. Loose fits leave room for a jack or pry bar to gain leverage, which defeats even strong locks. Position the keyhole downward to keep rain and debris out of the cylinder.
Lock to a fixed object that cannot be cut or lifted. A street sign or a proper bike rack beats a wooden fence post every time. Always lock your frame plus at least one wheel, and consider adding a secondary cable for the second wheel.
GPS trackers as secondary security
An Apple AirTag or a dedicated GPS tracker hidden on your e-bike does not prevent theft, but it dramatically improves recovery odds. We recommend tucking an AirTag into the seat tube or under the battery compartment, paired with a sturdy physical lock. The lock slows the thief down; the tracker helps you or the police find the bike after the fact.
Frequently Asked Questions
What is the best way to lock an electric bike?
Use two different lock types together. Combine a Sold Secure Gold or Diamond U-lock on the rear frame and wheel with a chain lock on the front wheel and a fixed object. Always lock to a proper bike rack or signpost, fill the internal locking area completely, and position keyholes downward. Add a hidden GPS tracker or AirTag for recovery if theft occurs.
What is the best way to protect my e-bike from theft?
Layer your security. Start with a Sold Secure Gold or Diamond rated lock from a trusted brand like Kryptonite or Hiplok. Register the lock with the manufacturer to activate any Anti-Theft Protection Offer. Park in well-lit areas with surveillance cameras when possible. Add a GPS tracker as a recovery backup. Insure the bike through your homeowner’s or renter’s policy or a dedicated e-bike policy.
How do I keep my electric bike from being stolen?
Park in high-traffic areas with security cameras when possible. Use two locks of different types to force a thief to carry multiple tools. Remove accessories like lights, computers, and bags when parking. Register your bike’s serial number with the national bike registry. Take photos of your bike and lock setup for insurance purposes. Never leave your e-bike parked overnight in a public area without a Sold Secure Diamond lock.
Which bike lock is the most theft-proof?
The Hiplok D1000 is the most theft-proof portable bike lock we tested, with independently verified Sold Secure Diamond and ART 4 Star ratings. Its 32mm graphene-reinforced shackle is specifically engineered to resist sustained angle grinder attacks. No portable lock is truly theft-proof against unlimited time and tools, but the D1000 buys you more time than any other consumer option in 2026.
