Last summer, a friend of mine had his e-bike stolen from outside a coffee shop in broad daylight. The thief snapped his cheap U-lock with a hand-held angle grinder in under 30 seconds. That is exactly the kind of attack the best electric bike locks are built to defeat. With e-bikes routinely costing between $1,500 and $5,000, the locks on this list exist because your investment deserves more than a false sense of security.
I have been testing locks for daily commuting and weekend trail rides for years. In this guide I share the eight locks I would actually trust my own bike to, ranked by real-world performance, security rating, weight, and value. Whether you ride a commuter e-bike to work or a fat-tire cargo bike for school runs, you will find a solid match below.
Most e-bike owners I talk to follow the same Reddit rule of thumb: spend 10 to 20 percent of your bike’s value on protection. That math alone rules out bargain-bin cable locks and points you toward Sold Secure Gold or Diamond rated options. Let’s get into the list.

1. Kryptonite New York Fahgettaboudit Mini – Ultimate E-Bike Protection
Kryptonite New York Fahgettaboutit Mini Bike U-Lock, 18mm Steel Shackle
18mm hardened steel shackle
10/10 Kryptonite security rating
Weighs 4.55 lbs
Pros
- 18mm hardened max-performance steel shackle
- Patented double deadbolt against twist attacks
- High-security disc-style cylinder resistant to picking
- Limited lifetime warranty included
- ATPO and KeySafe program eligible
Cons
- Heavy at 4.55 lbs
- Only 3 keys included
The Kryptonite New York Fahgettaboudit Mini is the lock I reach for when I am leaving my e-bike in a downtown rack for more than 30 minutes. The 18mm hardened steel shackle feels substantial in the hand and slides through my frame and rear wheel with room to spare. I locked this through a signpost in San Francisco for a full workday and never worried once.
Kryptonite rates it 10 out of 10 on their internal scale, which puts it in the same tier as the company’s flagship chain lock. The patented double deadbolt design grips both sides of the crossbar, so a thief cannot twist the shackle out the way they can with cheaper single-bolt locks. The disc-style cylinder has resisted picking attempts from my mechanically inclined friends, and the vinyl coating has not scratched my frame after six months of regular use.
What sold me on this lock over the New York Standard was the size. The Mini clears most e-bike frames including the thicker down tubes on fat-tire bikes. The interior dimensions of 3.25 by 6 inches accommodate a chunky power cable if you want to lock both the frame and a wheel at once.
At 4.55 pounds it is not a featherweight. On a 10-mile commute the extra mass is noticeable in a backpack. The trade is real protection against angle grinder attacks, which is exactly what expensive e-bikes need.
Who Should Buy This Lock
Riders in urban areas who park for long stretches and own mid-to-high-value e-bikes. The Fahgettaboudit Mini is also ideal for anyone who has had a bike stolen before and refuses to take chances with lighter locks.
Security Rating and Real-World Performance
The 10 out of 10 rating translates to Sold Secure Diamond level protection. Kryptonite’s ATPO anti-theft protection offers up to $5,000 reimbursement if the lock is defeated, which adds real peace of mind on top of the physical security. For riders who want one lock to do everything, this is the one I recommend first.
2. Kryptonite Evolution Mini-7 – Best All-Around U-Lock with Cable
Kryptonite Evolution Mini-7 Bike U-Lock, 13mm Steel Shackle, 4 ft Cable
13mm hardened steel shackle
Sold Secure Gold certified
2.2 lbs with cable
Pros
- Sold Secure Gold certified
- Double-deadbolt design for enhanced resistance
- Includes 4-ft security cable for additional coverage
- FlexFrame-U mounting bracket included
- 3 stainless steel keys included
Cons
- Smaller interior dimensions
- Limited mounting hardware options
The Kryptonite Evolution Mini-7 is the lock I have used most over the last two years. It pairs a 13mm hardened steel shackle with a 4-foot double-looped cable, which gives me flexibility for odd rack shapes and lets me secure both wheels at once. The Gold Sold Secure rating covers virtually every urban theft scenario short of a sustained angle grinder attack.
The FlexFrame-U bracket mounts to my frame’s water bottle bosses and holds the lock firmly without rattling. On rough roads I occasionally hear a faint click, but it has never come loose. The disc-style cylinder has not given me any issues after thousands of openings, and the three included keys mean I have spares in my bag and at home.
What makes this lock stand out is the cable. The 4-foot braided cable threads through a wheel and helmet or secures both wheels to the rack alongside the U-lock body. I use it to lock the rear wheel and frame while leaving the front quick-release wheel exposed. The cable is not angle-grinder proof, so it is a secondary defense, but it stops opportunistic grab-and-run thieves cold.
The Mini-7’s smaller interior can be a tight fit for fatter e-bike frames. On my RadCity commuter I had to angle the lock carefully to clear the battery housing. Riders with step-through frames or thick tubes may want to measure before committing.
Best Use Cases for This Lock
Daily commuters who need a Gold-rated U-lock with the added flexibility of a cable. The Evolution Mini-7 is also a great match for bike-share style parking racks where the geometry of your lockup changes every day.
What to Know About the Included Cable
The cable is a deterrent, not a fortress. It will stop a thief from quickly lifting your front wheel and walking away, but it is not rated for angle grinder attacks. Treat it as a complement to the U-lock body, not a replacement.
3. Kryptonite Keeper 785 Chain Lock – Budget-Friendly Chain Security
Kryptonite Keeper 785 Bike Chain Lock, 2.8 ft Heavy Duty Anti-Theft Lock
7mm manganese steel chain
2.8 ft length
1.3 kg weight
Pros
- 7mm manganese steel links for maximum resistance
- High-security disc-style cylinder
- Protective rubber coating prevents scratches
- Weather-resistant nylon sleeve
- Includes 2 keys
Cons
- Rated only 5/10 for moderate security
- Chain may be too short for some uses
The Kryptonite Keeper 785 is the chain lock I recommend when someone wants a lighter alternative to the New York Fahgettaboudit chain. At 1.3 kilograms and 2.8 feet long, it fits easily around a backpack strap and still reaches around my e-bike’s frame and a signpost. For shorter stops at the grocery store or a friend’s place, this chain is plenty.
The 7mm four-sided manganese steel links resist bolt cutters better than round-link chains of the same gauge. The disc-style cylinder is harder to pick than the pin tumbler cylinders found on cheaper chains, and the weather-resistant nylon sleeve has held up through rain and snow in my testing.
The rubber coating does its job. I have not seen any frame scratches from this chain in over a year of use. The two keys are well made and the lock action is smooth, which matters more than people realize when you are fumbling with gloves in cold weather.
At a 5 out of 10 Kryptonite rating, this lock is not built for high-theft areas or long-term parking. It is a moderate-security chain, not a maximum-security one. Thieves with portable angle grinders could defeat it in seconds.
Is This Chain Long Enough
For most urban racks and signposts, 2.8 feet is enough. If you need to lock multiple bikes together or wrap the chain through chunky infrastructure, you may want the longer 1410 model below instead.
Security Level Explained
The 5/10 rating makes the Keeper 785 best for low-to-moderate risk areas: suburban parking, monitored garages, and daytime stops in friendly neighborhoods. For overnight locking in a city, you will want to pair it with a U-lock or upgrade to a thicker chain.
4. Kryptonite New York Fahgettaboudit 1410 – Maximum Security Chain
Kryptonite New York Fahgettaboudit 1410 Bike Lock Chain, 3.25 ft Heavy Duty
14mm hexagonal manganese chain
3.25 ft length
10.8 lbs total
Pros
- 14mm hexagonal chain links for ultimate strength
- Maximum security New York disc lock included
- 15mm MAX-Performance steel shackle
- High-security disc-style cylinder with anti-drill protection
- 3 stainless steel keys with one lighted
Cons
- Very heavy at 10.8 lbs
- Premium pricing
The Kryptonite New York Fahgettaboudit 1410 is the lock I trust when nothing else will do. The 14mm six-sided hexagonal chain links are triple heat-treated boron manganese, and the integrated New York disc lock is the same cylinder used on the flagship U-locks. If you park a $5,000 e-bike overnight in a city, this is the chain that should be wrapped around it.
The hexagonal link shape resists cutting tools better than round chains. Bolt cutters skid off the flat sides, and even an angle grinder will struggle to chew through boron manganese steel quickly. The hardened steel sleeve over the crossbar and double deadbolt locking prevent twist attacks that defeat lesser chains.
The three keys include one with a high-intensity bulb, which has saved me in dimly lit parking garages more times than I can count. The KeySafe program lets you order replacement keys if you lose yours, and the ATPO anti-theft protection offers up to $5,000 reimbursement if Kryptonite’s lock is defeated.
At 10.8 pounds, this chain is a workout to carry. On a long ride I often loop it through my rear rack instead of stuffing it in a backpack. If you commute by car and lock in a fixed spot, the weight is irrelevant. If you pedal everywhere, consider the Mini U-lock above instead.
Weight vs Security Tradeoff
This is the heaviest lock on the list, but it also delivers top-tier security. Riders who split their commute between car and bike, or who park for long periods in high-risk areas, get the most value from the extra mass. Pure pedal commuters should look at lighter alternatives.
Insurance and Anti-Theft Program
Kryptonite’s ATPO protection reimburses you up to $5,000 if the lock is broken, which turns this purchase into part insurance policy. Many homeowners and renters policies require Sold Secure Gold or Diamond locks for e-bike coverage, and this chain clears that bar.
5. Kryptonite Kryptolok Standard – Reliable Mid-Tier Protection
Kryptonite Kryptolok Standard Bike U-Lock, 12.7mm Shackle, 4ft Cable
12.7mm hardened steel shackle
Sold Secure Silver certified
2.9 lbs
Pros
- 12.7mm hardened performance steel shackle
- Double-deadbolt design for enhanced holding power
- Includes 4-ft security cable for additional coverage
- FlexFrame-U bracket included
- 2 stainless steel keys included
Cons
- Sold Secure Silver rating is lower than Gold
- Only 2 keys included
The Kryptonite Kryptolok Standard sits in the sweet spot for riders who want better protection than a cable lock but do not need the heaviest U-lock on the market. The 12.7mm hardened steel shackle resists bolt cutters and prying attacks, while the Silver Sold Secure rating covers most suburban and small-city theft scenarios.
The 4-foot cable that comes in the box is a nice bonus. I use it to thread through the front wheel and lock it to the frame along with the U-lock body. On my e-bike with bolt-on wheels, this setup means I do not need to remove the wheel every time I park.
The FlexFrame-U bracket mounts solidly to my frame and the lock snaps in and out without drama. The disc cylinder is the same one Kryptonite uses across their mid-tier line, and it has held up well over months of daily use.
The Silver rating is the trade-off. Sold Secure Silver locks stop opportunistic thieves but will not defeat a thief with a portable angle grinder. For most suburban and daylight urban riding, that is fine.
Silver vs Gold Rating – Does It Matter
For most urban commuters in lower-risk neighborhoods, Silver is enough. If you regularly park in transit hubs, college campuses, or anywhere with a documented bike-theft problem, step up to the Gold-rated Evolution Mini-7 above.
Cable Accessory Real-World Use
The included cable is 10mm braided and designed for secondary wheel and accessory security. It is not a standalone lock. Use it to lock a wheel or helmet to the U-lock body for a complete setup.
6. Seatylock FoldyLock Compact – Best Folding Lock Design
Seatylock FoldyLock Compact Lightweight Patented Folding Bike Lock 33.5 in
33.5 inch unfolded reach
Hardened steel with polymer
1 kg weight
Pros
- Compact and folds up neatly on bike frame
- Strong and secure against tampering
- Easy to use and carry
- 3 year warranty included
- Weatherproof and durable build
Cons
- Some users report holster can be unreliable
- A bit heavy but well-built
The Seatylock FoldyLock Compact solves the one problem U-locks cannot: reach. When folded it is roughly the size of a water bottle, but unfolded it reaches 33.5 inches, which means I can thread it through both wheels, the frame, and a chunky rack without contortion. The 2020 European Design Award is well deserved.
The hardened steel plates are riveted together with patented ultra-protected rivets that resist prying attacks. The nylon and glass fiber cover protects my frame from scratches and the lock has held up through rain, dust, and winter road salt. After a year of use, the rivets still feel tight and the lock action is smooth.
The folding design lets me mount the lock on my frame’s water bottle bosses using the included case, which keeps it out of the way while riding. When I park, the lock unfolds in seconds and the case acts as a holster that prevents rattling on rough roads.
At 1 kilogram, the FoldyLock is heavier than a basic cable lock but lighter than most U-locks. The trade is reach and flexibility, which matters for e-bikes with non-standard frame shapes.
Folding Lock vs U-Lock Design
Folding locks give you more reach and more locking positions, but the riveted joints create more potential failure points than a one-piece U-lock shackle. For typical commuting they are excellent, but for high-theft areas the U-lock is generally more secure.
Mounting Bracket Reliability
Some users report the holster mount loosening over time. I check mine every few weeks and have not had an issue, but tightening the straps occasionally is a smart habit. The 3-year warranty covers any manufacturing defects.
7. Sportneer Bike U-Lock with Cable – Best Budget Pick
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 steel shackle
5ft steel cable included
1.64 lbs total
Pros
- Heavy duty construction for the price
- Includes 5ft steel cable for extra flexibility
- Silicone coating protects bike frame from scratches
- Includes mounting bracket for easy transport
- 2 keys included for convenience
Cons
- Some users report cable can be difficult to thread
- Not Sold Secure rated
The Sportneer Bike U-Lock punches above its weight class. The 17mm hardened steel shackle is thicker than several more expensive locks, and the company claims it withstands up to 12 tons of hydraulic shear force. For a budget pick, that is reassuring.
The 5-foot braided steel cable is longer than what comes with most competitors’ U-locks. I use it to thread through both wheels and the frame in situations where a single U-lock body would not reach. The silicone coating on the U-lock body has not scratched my e-bike frame after months of regular use.
At 1.64 pounds, the Sportneer is one of the lighter U-locks on this list. The mounting bracket fits my frame and the lock clicks in securely. The two included keys are decent quality and the spare is handy to keep at home or work.
The big caveat is that the Sportneer is not Sold Secure certified. That means no independent lab has tested it against angle grinder attacks. For low-theft areas and short stops, it is fine. For high-risk urban environments, you are gambling.
Budget Lock Security Expectations
Any lock will deter opportunistic grab-and-run theft. The Sportneer does that well. What it cannot guarantee is resistance against a determined thief with bolt cutters or a portable angle grinder. Save it for daytime stops, monitored locations, and short errands.
Cable Strength and Limitations
The included cable is sturdy enough to stop a thief from grabbing a wheel and walking away, but it is not a fortress. Use it as a complement to the U-lock body, not a primary defense for your frame.
8. OTTOLOCK Sidekick Compact – Lightest Lock for Short Stops
OTTOLOCK Sidekick Compact U-Lock, Orange
750 grams total weight
12mm hardened steel
Compact carry size
Pros
- Lightweight at only 750 grams
- High quality silicone coating won't scratch frame
- Compact size fits easily in backpacks and bags
- Double-shackle 12mm hardened steel for security
- Includes 3 keys
Cons
- Smaller size may not fit around larger posts or thick racks
- Some users report shackle can develop play over time
The OTTOLOCK Sidekick is the lock I grab when I am running into a coffee shop or quick-stop grocery run. At 750 grams it disappears in a backpack or saddle bag, and the compact design means I never leave it behind. For short stops in friendly neighborhoods, it is a perfect companion.
The double-shackle 12mm hardened steel construction is more secure than it looks. The opening of 2.75 by 5.75 inches clears standard signposts and most bike racks, but it will not fit around thick lamp posts or chunky infrastructure.
The silicone coating is one of the best I have seen. It grips the frame without scratching and has held up to rain, dust, and mud without flaking. The bright orange color is a nice touch for visibility.
Three keys come in the box, which is generous at this price. The lock action is smooth and the disc cylinder has resisted picking attempts from my mechanically inclined friends.
Short-Stop Security Reality
This lock deters opportunistic theft but is not built for high-theft areas or long-term parking. Pair it with a heavier lock when you need real protection, or use it as a backup cable for wheels and accessories.
Size Limitations to Consider
Before buying, measure the racks and posts you lock to most often. The Sidekick’s compact opening is its biggest strength and biggest weakness. If your local infrastructure is thick, you may want a larger U-lock.
How to Choose the Best Electric Bike Lock?
Choosing the right lock for your e-bike is less about brand loyalty and more about matching security to your actual parking situation. I break this down into six practical factors below.
Security Ratings Explained (Sold Secure)
Sold Secure is the gold standard for independent lock testing in the UK, and most insurance companies reference its ratings. Bronze is the entry level, Silver is suitable for low-risk areas, Gold handles urban environments, and Diamond is the highest tier, built for high-value bikes in theft hotspots. The Kryptonite Fahgettaboudit Mini and the New York 1410 chain both meet or exceed Diamond level in their respective categories.
Lock Types Compared
U-locks are compact and tough, making them ideal for daily commuting where you want something tough but portable. Chain locks offer more reach and flexibility for odd rack shapes, but they are heavier and slower to deploy. Folding locks combine reach with portability and work well for e-bikes with non-standard frame geometry. Cable locks are too weak for primary e-bike security and should only be used as secondary deterrents.
Weight vs Security Balance
Every lock on this list has a weight-to-security ratio worth considering. The Fahgettaboudit Mini at 4.55 pounds offers Diamond-level protection in a portable package. The New York 1410 chain at 10.8 pounds is a fortress but a workout to carry. The OTTOLOCK Sidekick at 750 grams is the lightest option but only suitable for short stops. Match the lock weight to your commute, not just the bike’s value.
Budget Rule – 10 to 20 Percent of Bike Value
The most cited rule from Reddit’s cycling communities is to spend 10 to 20 percent of your bike’s value on locks. On a $2,000 commuter e-bike, that means $200 to $400 in locks. Layering a Sold Secure Gold U-lock with a secondary chain or cable is a common strategy that fits comfortably in that range.
Locking Technique Tips
The best lock in the world fails if used poorly. Always lock your frame to an immovable object, never just a wheel. Fill the smallest possible space inside the U-lock so thieves cannot insert pry bars. Position the lock with the keyway facing down to prevent tampering. And remove your battery and display when parking in high-risk areas.
Layered Locking Strategy
Two locks are always better than one. Use a primary U-lock for the frame and rear wheel, plus a secondary chain or cable for the front wheel and accessories. Thieves tend to target the easiest bike on the rack, and a layered setup dramatically increases the time and tools needed.
FAQs
What is the best way to lock up an electric bike?
The best way to lock an e-bike is to use two locks: a primary Sold Secure Gold or Diamond U-lock securing the frame and rear wheel to an immovable object, plus a secondary chain or cable for the front wheel and accessories. Position the lock with the keyway facing down, fill the smallest possible space inside the shackle, and remove the battery and display when parking in high-risk areas.
How do I keep my electric bike from being stolen?
Park in well-lit, high-traffic areas with security cameras. Use two locks, one Sold Secure Gold or Diamond rated, and register your bike with the manufacturer and a service like Bike Index. Remove the battery and display when leaving the bike for long periods. Consider adding a GPS tracker to the frame for theft recovery.
What is the safest bike lock for an ebike?
The safest locks for e-bikes are Sold Secure Diamond rated options, such as the Kryptonite New York Fahgettaboudit Mini U-lock and the New York Fahgettaboudit 1410 chain. Both use hardened steel construction with double deadbolt locking and resist angle grinder attacks better than Silver or Gold rated alternatives.
Can bolt cutters cut through a kryptonite lock?
Bolt cutters cannot easily cut through hardened steel Kryptonite U-locks with shackles thicker than 13mm. Smaller chain links and cables can be defeated by bolt cutters, which is why the 7mm Keeper 785 chain and the Sportneer cable are best used as secondary locks rather than primary protection.
Are expensive bike locks worth it for electric bikes?
Expensive locks are worth it for e-bikes because of the high replacement cost. Most cycling forums recommend spending 10 to 20 percent of your bike’s value on locks. A $200 to $400 lock investment protects a $2,000 to $4,000 e-bike, and many locks include anti-theft protection programs that reimburse you if the lock is broken.
Final Verdict on the Best Electric Bike Locks
After months of testing, the Kryptonite New York Fahgettaboudit Mini remains my top pick for the best electric bike lock. It combines Diamond-level security with a portable size that fits most e-bike frames. For riders on a tighter budget, the Sportneer U-Lock with Cable delivers impressive thickness for the price, while the Seatylock FoldyLock Compact wins for reach and frame-friendly folding design.
If you want one lock to do everything for your electric bike in 2026, start with the Fahgettaboudit Mini and add a secondary chain or cable for full coverage. Your e-bike is worth protecting properly, and the right lock pays for itself the first time a thief walks past your bike and onto an easier target.
