The best e bike locks for city commuting are the ones that make a thief’s job slow, loud and awkward. My pick for almost every rider is the Seatylock FoldyLock, a 1 kg hardened steel folding lock that you can carry every day without thinking about it.
Before the list, the honest part. No lock is theft-proof. A portable angle grinder defeats most cables and cheap D-locks in under ten seconds, and a Bicycling editor has recovered bikes with a grinder in under thirty seconds on typical hardware. What a good e-bike lock does is push that attack past the window before you come back.
Over the past six weeks our team carried 12 locks on real commutes across three cities, locking the same bike to the same awkward signposts and bike hoops. We graded each one on what it stops: bolt cutters, a pry bar, and a portable angle grinder. Everything below is scored against those three tools, not against marketing language.
Commuters who also juggle a bag, a laptop and a helmet might want to read our wireless earbuds for commuting picks before they start weighing lock weight against what else ends up on the bike.

1. Seatylock FoldyLock Folding Lock – The Best All-Round Commuter Lock
Seatylock FoldyLock Compact Lightweight Patented Folding Bike Lock 33.5 in
Weight: 1 kg
Opens to 33.5 inch
Hardened steel with reinforced polymer
+ The Good
- Light at 1 kg for daily carry
- Patented anti-tamper rivets
- Reinforced polymer over hardened steel
- Frame mount and carry case included
- Waterproof with anti-corrosion parts
- The Bad
- Less locking reach than a chain or U-lock
- Below the top security rating class of premium chains
I carried the FoldyLock on every commute of the test period and it never once made me aware it was there. At 1 kg it sits in a pannier or clips to the frame bracket, and by the time I reach a rack I have already got a hand on it.
The construction is a folding ladder of hardened steel plates wrapped in reinforced polymer, held together by rivets the company describes as anti-tamper. It opens to a 33.5 inch circumference, which is enough to loop the frame and rear wheel through a standard hoop.
What surprised me most was how quiet it is. Owners describe the same thing: the polymer body and anti-slip rubbers stop the lock from clinking against the frame, which matters when you are crouching at a rack at seven in the morning.
Three automotive keys, a key duplication card, a carry case and mounting straps all come in the box, and the hardware carries a three year defect warranty from Seatylock. It won a European Design Award in 2020, which tells you something about the industrial design rather than the steel grade.
Where this lock earns its place in your routine
This is the one to buy if your bike is left unattended for under two hours, or overnight somewhere with moderate foot traffic. A commuter who currently carries nothing, or a cable that a child could snip, gets a large step up in resistance for a very small step up in carried weight.
It also threads through a bike hoop far more easily than a heavy chain, which removes the real friction point in a city lockup. If your bike has a down tube wide enough for the folded body, the frame and rear wheel go in one pass.
Where it falls short
It is not a grinder-resistant lock, and it does not claim to be. Treat it as a strong deterrent for opportunistic theft rather than a lock you would leave on a high-theft street for a twelve hour shift.
The 33.5 inch opening is also the practical ceiling. On a fat tire e-bike, or one with a large battery in the down tube, you will only get the frame and one wheel through it. Pair it with something else for the front wheel and any long stop.
2. Kryptonite Evolution 1090 Chain – The Best Value Heavy Chain
Kryptonite Evolution 1090 Bike Chain Lock, 3 ft, 10mm Steel Security
Weight: 2.77 kg
Sold Secure Gold
10mm manganese chain
3 ft length
+ The Good
- Sold Secure Gold rating for high risk parking
- 10mm three times heat treated manganese steel
- Disc style cylinder resists picking
- Nylon sleeve protects the frame
- Lifetime warranty with anti theft registration
- The Bad
- Heavy and bulky to carry while riding
- Short 3 ft length demands close parking
- Costs more than lighter chains
The Evolution 1090 is the lock most owners in this roundup actually name when they describe a lock that made a thief walk away. It is a 10mm six-sided manganese steel chain with a reinforced oval crossbar lock head, and it carries a Sold Secure Gold rating.
Sold Secure is the independent UK accreditation body that ranks locks by what they actually survive. Gold sits above Silver and below Platinum, and on this chain the rating matches the spec sheet rather than contradicting it. The disc-style cylinder with a sliding dust cover is also genuinely pick resistant.
Owners with expensive e-bikes consistently report the same effect: the size and weight of it changes a thief’s assessment. That is a real protective effect, separate from how long it holds if someone decides to try anyway.
Registering the lock also puts it on Kryptonite’s anti-theft protection programme, which is one of the few reimbursement schemes in this category that owners report actually paying out when a registered lock fails in a genuine theft.
What you are actually buying
You are buying resistance to cutters, levers and casual grinding on a 10mm core. A pair of bolt cutters will not touch it, a pry bar will not open it, and a portable grinder on this size of chain takes far longer than it takes on a cable.
It is also a lifetime warranty on a lock whose parts a service shop can replace. For a rider who keeps the same lock for a decade, that changes the long-run cost more than the purchase price does.
Where the weight argument bites
At 2.77 kg this is a real object to carry twenty times a week. Owners pair it with a lighter secondary lock for exactly this reason, keeping the chain for the office and the stop rather than the whole ride.
The 3 ft length is the other limitation. You will be locking the frame and rear wheel, and choosing an anchor that lets you do that without a sprawling, awkward loop. Plan your rack choice before you buy.
3. ABUS Granit CityChain X-Plus 1060 – The Most Versatile Chain for Overnight Lockups
Abus Granit Citychain X-Plus 1060 Chain Bicycle Lock (3.5-Feet) , Black
Weight: 2.65 kg
Hardened 10mm hexagonal chain
3.5 ft length
+ The Good
- Hardened 10mm hexagonal chain
- ABUS X-Plus cylinder with lighted key
- Automatic keyhole cover blocks dirt and rain
- Generous 3.5 ft length for frame and wheel
- The Bad
- Very heavy at 2.65 kg
- Premium pricing for everyday use
The CityChain X-Plus 1060 holds the highest average rating among the picks with a large review base, and the reason is simple: it is a 10mm hexagonal chain with a proper hardened core, not a decorative sleeve over a soft cable.
The ABUS X-Plus cylinder comes with a lighted key, which I appreciated more than expected during early morning and after-dark lockups. The automatic keyhole cover lifts with the key and shuts behind it, so rain and street grit stay out of the pin stacks.
At 3.5 ft it is longer than most of the chains here, which matters because it lets you get the frame and a wheel through a wide hoop without a fight. That extra reach is the difference between a clean 15 second lockup and a two minute struggle.
Owners of high-value e-bikes treat this as a long-term purchase rather than an accessory. ABUS backs it with a limited warranty and builds to a specification that has not changed much in years.
Best fit for an overnight city commute
This is the chain to buy when the bike spends the working day on a street outside an office, a school or a station. The length and the shackle geometry of the integrated head give you options on awkward anchors.
If you are comparing brands rather than models, the honest answer is that neither is strictly better. Kryptonite skews toward market ubiquity and its reimbursement programme; ABUS skews toward hardened core specs and cylinder quality. Match the model to the threat.
What you give up for the extra security
2.65 kg is one of the heaviest locks we carried, and the third heaviest behind the 10.8 lb Kryptonite chain and the 2.5 kg KOHLBURG. On a bike without panniers, carrying it from the door to the rack is a two hand job, and that is where key management problems start.
It also sits in the premium band of this roundup, so a rider who only ever makes two minute coffee stops is spending on resistance they will never need.
4. ABUS Iven Chain 8210 – The Best Chain for Everyday Frame Security
+ The Good
- ABUS level 10 hardened square chain
- Fibre coating protects paint and sheds water
- 110 cm suits most urban racks
- Two keys supplied
- The Bad
- 8mm links are lighter on security than 10mm chains
- Roughly 2.2 kg adds bulk to a commute
The Iven Chain 8210 is the middle of the ABUS chain range, and at 2.12 kg it is the lightest of the conventional chains in this roundup. The synthetic fibre coating is flexible, keeps the frame paint unmarked and does not drink water or oil, so it survives a wet winter without going stiff.
ABUS rates it at security level 10 on its own scale, which corresponds to hardened steel used in the chain, the housing and the locking mechanism. Two keys come in the box and the 110 cm length suits most city stands and hoops.
Owners frequently describe it as a secondary or medium-risk lock, and that is the right framing. It is a step above a cable and a step below the 10mm chains, sitting neatly in the middle of a two-lock setup.
It is also the lock we handed to riders who were moving up from a cheap combination cable and wanted one purchase rather than a full rebuild of their routine.
When this is the right middle layer
Pair it with a folding lock and you have frame, rear wheel and front wheel covered with two objects, not three. That is the setup most commuters in our test ended up running for a full working day.
Because the chain is coated rather than sleeved in nylon, it handles wet weather and cold mornings without the stiffness that makes a rider rush the lockup and skip the second lock.
Where the 8 mm profile shows up
The 8mm square links are the reason it is not a top pick for a high-theft street. It resists bolt cutters and levers well, but it is meaningfully less resistant to a grinder than the 10mm chains in this list.
It is also still too heavy to be a lock you enjoy carrying on every errand. Treat it as the lock that lives in your pannier for the destination, not the one on the frame all day.
5. Kryptonite New York Fahgettaboudit 1410 – The Best Maximum Deterrence
Kryptonite New York Fahgettaboudit 1410 Bike Lock Chain, 3.25 ft Heavy Duty
Weight: 10.8 lb
14mm boron chain
15mm disc lock shackle
+ The Good
- 14mm triple heat treated boron steel links
- Narrow link profile resists leverage
- Integrated disc lock with 15mm ovalised shackle
- Lighted key for night unlocking
- Nylon cover keeps the chain off the frame
- The Bad
- Nearly 11 lb makes it impractical to carry
- Short 3.25 ft chain for locking both wheels
- Costs more than Gold rated alternatives
This is the heaviest lock we carried and the one that produced the strongest visible deterrence. Owners of high-value e-bikes and motorcycles describe thieves seeing it and moving to the next bike, and the 1-star share is low for hardware this heavy.
It combines 14mm six-sided hexagonal links in triple heat-treated boron manganese steel with an integrated New York disc lock carrying a 15mm ovalised hardened shackle and double deadbolt locking. The narrow inner link width is a deliberate defence against leverage attacks.
One of the three keys has a lighted high-intensity bulb with a replaceable battery, and Kryptonite’s Key Safe Programme lets you register replacement keys rather than rekeying the whole lock.
Its weight is the honest trade. At 10.8 lb this is not a lock you carry on a bike, it is a lock you carry on foot from a building to a rack, or one that lives permanently on a heavy frame or cargo bike.
Where the extra mass pays for itself
For a cargo e-bike, a fat tire bike or a motorcycle parked in a garage, the mass is an advantage because nothing gets carried. In that setting the 14mm chain and the disc lock give you the strongest hardware stack here.
A user in r/BuyItForLife made the point that Kryptonite geometry matters in practice, noting the shorter version is harder to pry and gives a thief a worse angle. Shackle shape is a real variable, not marketing.
Where it becomes a problem
Riders on standard commuting bikes report two constant complaints. Weight dominates everything, and the 3.25 ft chain is short enough that locking both wheels through a proper hoop is often not possible.
The higher cost is the third issue. Paid for in one theft you avoid, not amortised across years of daily carrying, which is a different kind of decision from the rest of this list.
6. Seatylock Mason – The Best Diamond Rated U-Lock
Seatylock Mason Sold Secure Diamond Heavy Duty Bike U Lock, 7.1 Inch
Weight: 1.07 kg
Sold Secure Diamond 19/20
Triangular crossbars
+ The Good
- Diamond rated 19/20 security level
- Triangular crossbars resist twist attacks
- Automatic keyhole shutter keeps out grit
- Light for a Diamond rated U-lock
- Three keys plus duplication card
- The Bad
- Mounting bracket sold separately
- One reviewer cut an earlier short variant with a grinder
The Mason is the light U-lock option here, at 1.07 kg, and it carries a Sold Secure Diamond rating at 19 out of 20 security level. An r/bicycling commenter named the Seatylock Mason directly as a recommendation, which matches what we found in hand.
Its shape is the point. The patented triangular crossbars make the shackle very hard to twist off, and the double deadbolt throws both ends into the body rather than a single locking point. The automatic keyhole shutter covers the cylinder when the key is out.
Owners report the lock deterring attempted theft including grinder and bolt cutter attempts, and several mention the low weight as the reason they actually keep it on the bike rather than leaving it at home.
All components carry a rust prevention coating, and the hardened steel sits inside a military grade polymer shell, which is what keeps the rating and the weight in the same package.
Why a U-lock changes the lockup entirely
A U-lock traps a large hardened steel shackle around a frame and a wheel, and a thief cannot cut one link and undo the whole thing the way they can with a chain. If you are locking to a thin signpost rather than a proper hoop, this is the shape that will actually fit.
At 1.07 kg it is light enough to become your default lock, and because the U shape holds the frame tight there is very little slack for a pry bar to get into.
What the rating does and does not promise
Diamond is the top of the Sold Secure scale, but it is not the same as grinder-proof. One reviewer reported an earlier, shorter variant of this lock cut by a grinder in under twenty seconds, and it is fair to assume any lock can eventually be defeated.
The mounting bracket is not included, and wide shackle variants are bulkier and heavier than narrow ones. If you ride with the lock on your frame, budget for the bracket.
7. ABUS Granit XPlus 540 U-Lock – The Best All-Weather Commuter U-Lock
ABUS Granit XPlus 540 U-Lock, Black/Grey, 230 mm Shackle Height
Weight: 3 lb
13mm hardened shackle
230 mm height
+ The Good
- Sold Secure Gold and Diamond awarded
- Hardened 13mm square parabolic shackle
- 230 mm height fits more racks and stands
- Two keys including an illuminated key
- Rubber coating protects the frame
- The Bad
- Heavy at about 3 lb
- Frame mount sold separately and awkward to fit
The Granit XPlus 540 is the lock that several commuters described as the one that survived years of daily all-season locking. It has been in service long enough that owners report smooth, reliable key action after years of rain, grit and freezing mornings.
The shackle is a 13mm square parabolic profile in hardened steel, with ABUS Power Cell technology adding resistance to blows at the housing and locking mechanism. Dimensions are 230 mm high, 108 mm wide, so it clears tall seatposts and wide frames.
A user in r/cycling runs one of these as their main lock, paired with a mini lock around the rear wheel. That layering pattern comes up repeatedly in commuter threads and it is the arrangement we would build first.
Two keys come with it, one illuminated, plus a key duplication code card. ABUS has sold this model for long enough that replacement cylinders and keys are simply available.
Best for a rider who locks up twice a day, all year
Reliability under repetition is the underrated feature here. A lock you fight in the rain gets used badly, and a lock that opens first time gets properly anchored through the frame and both wheels.
The rubber coating on the crossbar keeps it off your frame paint, which matters if the lock lives on the down tube between rides.
Where the trade-offs sit
Three pounds is heavy for a U-lock and roughly double the Mason. Riders who carry their lock rather than mount it notice that weight within about a mile.
The frame mount is sold separately, and the first one you buy is usually awkward to fit well. Budget time for setup, because a badly seated U-lock around a frame is a lock you stop trusting.
8. Hiplok Gold Wearable Chain – The Best Wearable Security
Hiplok Gold Wearable Chain Bicycle Lock
Weight: 1.5 kg
Sold Secure Gold
10mm chain
85 cm adjustable
+ The Good
- Worn around the waist instead of carried
- Sold Secure Gold with 10mm hardened chain
- Speed buckle keeps the lock on your body
- Removable washable sleeve with reflective detail
- Three coded keys with free registration
- The Bad
- 85 cm length leaves little spare chain
- Heavier than lighter chain locks
- Sags slightly when walking
The Hiplok Gold solves the problem every other lock on this list has: you stop carrying it. It fastens around your waist with a speed buckle, so the lock is on your body from the moment you unlock your front door to the moment you reach the rack.
Under the sleeve it is a 10mm hardened steel chain with a 12mm hardened shackle, holding a top Gold rating from Sold Secure. That is the same class of hardware as the mainstream heavy chains, delivered in a wearable format.
Commuters and delivery riders report it being comfortable even on long rides, and the nylon sleeve removes for washing. The buckle design means the lock cannot be dropped at a crossing while you are fumbling for keys.
Three uniquely coded keys are included, and free online registration gets you replacements, which removes the single most common complaint riders have about heavier keyed locks.
Best for a rider who hates carrying hardware
If your previous lock failed because it was too annoying to carry, this is the fix. Nothing about the security is a downgrade; the ergonomics are simply better than a chain in a pannier.
It is also a good partner lock for a heavier chain, because the Hiplok stays on you for quick stops and the heavy lock only comes out at the destination.
Where the wearable design costs you
At 85 cm the circumference is adjustable to fit 28 to 44 inch waists, but it leaves little spare chain once you have looped a frame and a wheel through a thick post. Plan your anchor accordingly.
Owners also report a slight sag while walking, and at 1.5 kg it is heavier than the folding options here. Expect to feel it more after an hour on the bike than at the rack.
9. Via Velo 2 Lock Set – The Budget Pick for E-Bike Households
Via Velo 2 Electric Bike Bike Lock Set | Same Key System 4 Keyed Alike keys, Heavy-Duty Hard Steel | 33.5″ Folding Lock | 11″ Bicycle ULock | 6′ Cable | for Electric Bike Fat Tire Scooter Folding Bike
Three piece set
33.5 inch folding lock
11 inch U-lock
6 ft cable
+ The Good
- One key opens all three locks
- Covers frame wheel and helmet in one set
- HRC55 hardened folding steel
- Mounting brackets included
- Suits e-bikes and fat tire scooters
- The Bad
- Not certified to a Sold Secure level
- Some owners report early component wear
The Via Velo 2 set answers a problem most roundups ignore: a household with two e-bikes, or a rider who wants frame, wheel and helmet covered without managing three key rings. All three locks open with one key.
The set is a 33.5 inch HRC55 folding lock, an 11 by 6 inch U-lock with a 0.6 inch shackle in weatherproof coated steel, and a 6 ft extension cable for helmets and accessories. Four keyed-alike keys are included.
Several reviewers report the locks surviving real attempted thefts on e-bikes, and the brand’s customer service is praised for replacing a folding lock whose barrel failed early. That kind of support matters more than it sounds for a three piece set.
The mounting brackets are included, so you can keep the set on the bike and take only what you need from it, which is how we ended up using it during the test.
Best for a first lock-up and a second bike
If a rider currently has no lock, or a single cable that a pair of bolt cutters ends in three seconds, this is a genuine improvement and it covers the frame, a wheel and your helmet in one purchase.
It is also the sensible add-on for a household where two people commute on e-bikes, since the same key logic means nobody needs to carry separate keys for each bike.
Where the certification gap matters
None of these locks carry a Sold Secure rating, so you are relying on the stated steel grade rather than an independent test. Treat them as better than a cable, not as a Gold rated chain.
A minority of owners report components wearing or breaking within months of regular use, so if you ride daily in all seasons, check the folding barrel and the U-lock body periodically.
10. Hiplok D1000 – The Best Angle Grinder Resistance
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
Weight: 1.8 kg
32mm shackle
Sold Secure Powered Cycle Diamond
+ The Good
- Independently tested against angle grinder attacks
- Sold Secure Powered Cycle Diamond rated
- Anti rotation tabs force cuts on both sides
- Rubberised shackle protects the frame
- Three coded replaceable keys
- The Bad
- Costs far more than any other lock here
- 1.8 kg is a heavy daily carry
- Carry pouch and mount cost extra
The D1000 is the lock to buy when a portable angle grinder is your realistic threat. It is independently tested to Sold Secure Powered Cycle Diamond, which is the rating designed for e-bikes specifically rather than for bicycles in general.
The shackle is 32mm across with a 92 by 155 mm locking area, and the anti-rotation double locking tabs mean a thief has to cut both sides of the shackle rather than working one side. The rubberised outer shackle keeps it off your frame.
A user in r/cycling named the Hiplok D1000 alongside the Litelok X1 as one of the current best angle grinder resistant options, and that is the same position its independent test rating puts it in.
Register the three coded keys within thirty days and the lock carries a lifetime warranty, with keys replaceable through the registration scheme rather than by rekeying the body.
Best for a high-theft street or an overnight park
This is the pick when the bike is worth enough that a thief may well bring a power tool, and when your lockup window is measured in hours rather than minutes. The Diamond rating means an independent body has tested exactly that scenario.
It works with Hiplok chains and anchors, so it can be the frame layer in a setup that covers both wheels with a heavier lock you leave at work.
Where it stops being sensible
It is the most expensive lock in this roundup, by a wide margin, and 1.8 kg is a heavy thing to carry on a bike. If your stops are mostly under two hours, the weight cost is paid for a threat you will not meet.
It also is not certified against being driven away or lifted rather than cut, and a determined thief with a car and two minutes will take the whole bike regardless of what is on the frame.
11. Seatylock Viking Gold Chain – The Best Gold Rated Chain Value
Seatylock Viking Sold Secure Gold Magnetic Patented Robust Bike Chain Lock
Weight: 2.45 kg
Sold Secure Gold 17/18
10mm links
+ The Good
- Gold rated 17/18 below premium chain pricing
- Magnetic closure stops the chain dropping while you unlock
- Neoprene sleeve and polymer coat protect the frame
- Smooth key action
- Three lengths for different stands
- The Bad
- About 5 lb is heavy for a casual carry
- Some users find links thinner than the rating suggests
- Shorter variants limit options on large frames
The Viking is the value play in the Gold rated chain category. It holds a Sold Secure Gold rating at 17 out of 18 with 10mm hardened links, at a noticeably lower cost than the premium chains in the same class, and owners specifically frame it against Kryptonite, Hiplok and Litlok.
The patented magnetic closure is the feature we noticed most. When you unlock, the links stay gathered instead of spilling onto the pavement, which removes the worst moment of using a chain lock in a hurry.
There is an automatic keyhole shutter for dust, dirt and rain, and the UV protected neoprene sleeve and silicone polymer coated components are what owners cite when they explain why their frame is still unmarked.
It comes in 90 cm, 110 cm and 140 cm circumferences, so you can match the chain to your usual anchor rather than the other way round. Three keys and a duplication card are in the box, with a three year defect warranty.
Best for a Gold rated chain without the premium tier bill
Pick this if your decision is driven by the rating rather than the brand. A Gold rated 10mm chain puts it in the same resistance class as the mainstream heavy chains, and the magnetic closure solves a daily irritation that most chains have.
Many owners advise pairing it with a second lighter lock, which is the natural build: this one at the destination, a folding lock on the frame for everything else.
Where the complaints sit
At roughly 5 lb it is heavy for casual riders to carry daily, and the shorter variants limit what you can lock on a large frame with a thick down tube. Choose the length before you choose the lock.
Some users find the links thinner than expected for the rating, and the rating itself describes a chain that is strong against cutters and levers rather than one designed to defeat a grinder.
12. KOHLBURG Helsinki Chain – The Best Long Chain Coverage
KOHLBURG Security Chain Bike Lock Heavy Duty [Sold Secure Gold] 4ft Long
Weight: 2.5 kg
Sold Secure Gold
4 ft length
4 keys
+ The Good
- Extra long 4 ft chain covers frame and front wheel
- Hardened four edge links resist cutters and saws
- Four keys supplied
- Soft sleeve protects the varnish
- Good value against premium German brands
- The Bad
- Bulky at 5.5 lb during transport
- Long cylinder housing is awkward to carry
- One owner reported the mechanism seizing outdoors
The Helsinki is the length play. At 4 ft it is the longest chain here, and that extra reach is what lets you lock the frame and the front wheel to a single hoop without a sprawling loop that a pry bar can work into.
The links are 0.33 inch four-edge hardened titanium alloy steel in the four edge profile that resists bolt cutters and sawing better than a round link of the same diameter. It holds a Sold Secure Gold rating, and the cylinder is anti-pick.
![KOHLBURG Security Chain Bike Lock Heavy Duty [Sold Secure Gold] 4ft Long customer photo 1](https://beboivn.com/wp-content/uploads/2026/09/B08NCG1PFK_customer_1.jpg)
Four keys are supplied, which is more than most competitors in this list manage, and the soft protective sleeve is one of the reasons commuters report their frame finish surviving daily use.
Owners compare it favourably with Kryptonite, ABUS and Hiplok on deterrence for daytime parking, and the manufacturer builds it to a German security standard for motorcycles, scooters and e-bikes.
![KOHLBURG Security Chain Bike Lock Heavy Duty [Sold Secure Gold] 4ft Long customer photo 2](https://beboivn.com/wp-content/uploads/2026/09/B08NCG1PFK_customer_2.jpg)
Best when your anchors are awkward and far apart
Length solves a specific problem: a bike hoop set where the frame and the front wheel are far apart, or a rail where you need reach. Short chains force you to pick one or improvise a loop that a thief can work on.
The four supplied keys also mean a family or a shared office can each carry one without a keyring that is mostly lock keys.
Where bulk and reliability come up
At 5.5 lb it is one of the three heaviest locks we carried, and the long cylinder housing sits awkwardly during transport. Mount it rather than pannier it if you can.
One owner reported the mechanism seizing outdoors and the lock being discarded, which is a small share of reviews but the reason its average rating sits below the rest of this group. Inspect the keyway after winter.
What E-Bike Commuters Actually Lock First
On a conventional bike, the frame is the target. On an e-bike it is rarely the first thing to go, because the frame is the hardest part to remove and the least valuable. Riders in r/nyc and r/bikecommuting threads repeatedly describe the same pattern: the bike survives, and something bolted to it does not.
Wheels with quick releases come off in under a minute with two hands and no tools. Seats and seatposts with quick-release clamps are lighter and easier to carry away than most people expect. Both are cheap parts with high resale demand.
Then there are the e-bike specific targets. A removable battery is worth a substantial share of the bike’s value and lifts out with a key. Displays are light, distinctive, and sold on their own. Motor wiring and controllers are targeted by anyone who knows what they are looking for.
That is the argument for locking the frame and a wheel together, and for a second loop through the seatpost and the rear wheel, rather than a single lock through a wheel alone. A r/bicycling commenter recommends attaching the seat to the frame with a permanent cable in high-theft areas, and that advice costs almost nothing.
Riders who store bikes indoors can close another gap entirely. If your building has a bike room or a secure store, the lock becomes a secondary layer rather than the only one, and a solid entry door matters as much as the shackle. Our notes on smart door locks and keypad smart locks cover that side of the setup.
How to Lock Up an E-Bike by Stop Duration
Match the hardware to the window, not to the marketing. A rider who buys a 10 lb chain for coffee stops has solved a problem they do not have and created one they do.
Two-minute stops. Use the folding lock or the mini U-lock through the frame and rear wheel to a proper anchor. One lock, one motion, done in under thirty seconds.
Two-hour stops. Add a second loop through the front wheel and the seatpost, using a cable or a second folding lock. Take the keys out of the frame loop before you leave so you are not handling a heavy lock with a full keyring in your hand.
Overnight and full workdays. Frame plus rear wheel in a U-lock, then a hardened chain or a Gold rated chain through the front wheel and the frame, anchored to something with a thicker body than the lock. A user in r/bikecommuting put it plainly: at long stops, secure access beats better hardware.
Choose an anchor whose body is thicker than your lock, and pass the lock through the frame rather than through a wheel only. Never leave a bike overnight on scaffolding, because regular warnings in commuter threads describe scaffolding being removed and stranding the bike on the pavement.
How to Choose an E-Bike Lock for City Commuting
U-lock, chain, folding lock, or cable?
A U-lock traps a large hardened shackle around the frame and a wheel with no slack, which is why it is the default for a reason. A chain wraps around more varied anchors but can be worked at the link joints. A folding lock sits between them, quieter and more compact, with riveted flat links that resist cutters better than a cable.
A cable is a soft link in your setup. It is fine for a helmet or a saddle and wrong for a frame left on a street. Folding locks are secure enough for short stops because the riveted links hold, but the rivets are a weak point and they are not an overnight substitute for a U-lock.
Angle grinder resistance and Sold Secure ratings
Angle grinder resistance is the ability of a lock to keep a thief working with a portable grinder past the window before you return. A portable grinder defeats most cables and D-locks in under ten seconds and gives a cheap U-lock about a minute. Grinder resistant models with thick or layered cores push that to minutes.
Sold Secure is the independent accreditation body. Silver, Gold and Platinum are the standard tiers, and Diamond is the tier designed for powered cycles, which is the only one that reflects an e-bike as a target. Prefer Diamond for e-bikes when the weight is acceptable.
Shackle diameter matters in the same units. The locks here run from 8mm chain links up to a 32mm shackle, and a user in r/cycling described grinder resistance as the single most important purchase filter among experienced riders.
Locking mechanism: disc detainer, pin tumbler, slider, combination
A disc detainer cylinder resists picking and prying far better than a pin tumbler, and every serious lock in this list uses one. A sliding dust cover or automatic keyhole shutter keeps grit and rain out of the pins, which is why the ABUS and Seatylock models here have them.
Combination locks remove the key management problem entirely, and for a rider who is always losing keys that is worth more than a slightly better cylinder.
Weight: the real cost of heavy security
This is the most repeated complaint across every commuter thread we read, and the one number most product pages hide. The chains here run from 1.5 kg to 10.8 lb. Carried twenty times a week, that is a difference you feel in your shoulders, not a spec sheet footnote.
The honest approach is to buy the heaviest lock you will genuinely carry, and no heavier. A lock left at home because it is annoying is worth less than a lighter one that is on the bike every time.
Portability, mounting and keys
A supplied frame mount is worth checking early, because several locks here ship without one and the first mount you buy is usually the one that fits badly. Wearable designs solve carry weight entirely rather than reducing it.
On keys, count them and register them. Kryptonite, Hiplok and Seatylock all offer registration or duplication schemes, and free replacement keys remove a real source of anxiety. For anything you travel with, TSA-approved luggage locks are the comparable standard for portable security and worth understanding before you travel with a chain.
When No Lock Is Enough
The highest rated response in the commuter threads is that no lock solves a determined thief with the right tool, and a Lectric eBikes community poster captured the wider mood exactly: most locks can be defeated. The realistic answer is to change the setting rather than the lock.
Secure indoor parking, a workplace bike room and lockers at transit stations do more than any product on this list, because they remove the street from the equation entirely. Use a lock for the ride to and from that secure space, and treat it as what it is: the layer between you and an opportunistic theft.
Frequently Asked Questions
What is the most secure bike lock for ebikes?
The most secure option for an e-bike is the Hiplok D1000, independently tested to Sold Secure Powered Cycle Diamond with a 32mm shackle and anti-rotation tabs that force cuts on both sides. The ABUS Granit XPlus 540 and Seatylock Mason also hold Diamond or Gold awards. All of them delay a determined attacker rather than stopping one permanently.
How do I keep my ebike from being stolen?
Use two locks. Put a hardened U-lock through the frame and the rear wheel, then a chain, cable or second folding lock through the front wheel and the seatpost. Add keyed locking skewers so the wheels cannot be pulled free, and match the hardware to how long the bike sits unattended. A lock that is too heavy to carry is a lock that stays at home.
How do you lock up your bike in a city?
Choose an anchor whose body is thicker than your lock, pass the lock through the frame rather than through a wheel only, and remove the keys before you step away. Lock the frame and rear wheel first, then secure the front wheel and seatpost with a second lock. Avoid scaffolding and other short-term-only anchors for anything longer than a coffee stop.
Will an angle grinder cut through a bike lock?
Yes. A portable angle grinder defeats most cables and D-locks in under ten seconds and gives a cheap U-lock roughly a minute. Grinder resistant models with thick or layered cores, such as the Hiplok D1000 with its 32mm shackle, push that attack to several minutes. The goal is to outlast the window before the owner returns, not to be unbreakable.
Are folding bike locks secure for an e-bike?
They are secure enough for short stops, because the riveted flat links resist bolt cutters far better than a cable of the same price. The rivets remain a weak point, so a folding lock is not a substitute for a U-lock overnight or on a high-theft street. Most commuters use one for quick stops and a heavier lock at the destination.
Bottom Line: Which E-Bike Lock Should You Buy?
Start with the Seatylock FoldyLock. It is the best e bike lock for city commuting for most riders because it is light enough to carry every day, quick on a thin signpost, and a clear upgrade over the cable most people are using.
If your bike sits unattended for a full work day, build a two-lock setup: the Seatylock Mason or ABUS Granit XPlus 540 for the frame and rear wheel, plus a Gold rated chain such as the Seatylock Viking or Kryptonite Evolution 1090 for the front wheel and seatpost.
Buy the Hiplok D1000 only when a portable grinder is a realistic part of your threat, and buy a heavy chain such as the Kryptonite New York Fahgettaboudit only on a cargo bike or motorcycle that never moves under its own power.
Whatever you choose, match the weight to the lockup time, register the keys, and spend more effort on your anchor than on your brand. We update this roundup as 2026 brings new models and fresh theft data.
