Choosing the best lock for cargo bike security depends on your daily habits, where you park, and how much weight you’re willing to carry. Cargo bikes are high-value targets that often require more than one security method to deter theft effectively. While some riders prioritize the extreme resistance of the Hiplok D1000, others prefer the reach and flexibility of the Kryptonite Evolution 1090.
1. Hiplok D1000 Anti-Angle Grinder Bike Lock
Best for: Someone who parks a high-value bike in areas with high theft risk.
This lock is engineered to withstand severe, sustained attacks from angle grinders, a common tool used by thieves in urban settings. Its 32mm shackle and anti-rotation design force a thief to cut through both sides of the lock, which is a significant deterrent for anyone using power tools.
The design is focused on portability at 1.93kg, making it a manageable addition to a cargo bike setup. However, it isn’t for someone who needs to secure their bike to very thick poles or multiple anchor points, as the locking area is limited to 92 x 155mm.
Good if:
- You prioritize resistance against power tool attacks.
- You want a lock with an official Sold Secure Diamond rating.
- You appreciate having a lifetime warranty after registration.
Skip it if:
- You frequently need to lock your bike to very wide objects.
- You prefer a flexible chain over a rigid U-lock.
2. Kryptonite New York Fahgettaboudit 1410 Bike Lock Chain
Best for: A user who needs maximum security and doesn’t mind carrying heavy gear.
This chain is built with 14mm six-sided links made from triple heat-treated boron manganese steel. It’s designed specifically for high-theft areas where standard locks might fail, providing extreme strength against leverage and cutting attacks.
The heavy weight of 15.25 pounds means this is best suited for bikes that stay in one place or for riders who have a dedicated storage setup on their cargo bike. It isn’t for a rider who wants a lightweight or compact solution for quick trips around town.
Good if:
- You’re locking up in a high-risk urban environment.
- You require a chain that resists leverage attempts on the links.
- You want the security of a heavy-duty disc lock.
Skip it if:
- You need to carry your lock in a small bag.
- You want a lightweight setup for daily commuting.
3. KOHLBURG Heavy Duty Anti Theft Chain Lock (Sold Secure Diamond)
Best for: Someone needing extra length to secure a bike to difficult, wide objects.
At 4 feet long, this chain offers significant reach, making it easier to lock a large cargo bike to trees or wide streetlamps. The massive 0.43-inch square links are designed to resist bolt cutters, and the entire system is certified with a Sold Secure Diamond rating.
The weight is a major factor here, as the chain is 10 pounds and intended for heavy-duty use. It isn’t for a rider who needs a portable, lightweight lock for frequent stops throughout the day.
Good if:
- You need extra length to reach distant anchor points.
- You want a lock with a high security rating for insurance.
- You prefer a lock that includes a dust cover for the cylinder.
Skip it if:
- You want a compact lock that fits in a pocket.
- The 10-pound weight is too much for your regular ride.
4. Kryptonite New York Long Shackle Bike U-Lock
Best for: A rider who needs a U-lock that fits around oversized frames or thick posts.
The 16mm hardened steel shackle provides excellent resistance against cutting, while the long 10.25-inch interior length gives you more room to maneuver when locking your bike. It features a double deadbolt design that protects against twist attacks.
This lock is a solid middle ground for security, but its size can make it awkward to carry compared to a standard U-lock. It isn’t for someone who prioritizes a small, tight fit that leaves no room for leverage inside the shackle.
Good if:
- You need extra shackle length to reach around bike racks.
- You want a lock with a high-security disc-style cylinder.
- You value the optional anti-theft protection coverage.
Skip it if:
- You want the most compact lock possible.
- You prefer a chain for more flexibility.
5. Kryptonite New York Standard Heavy Duty U-Lock
Best for: The daily commuter who parks in high-risk areas and wants a reliable U-lock.
This is a classic high-security U-lock with a 16mm shackle that resists prying and cutting. It includes a frame bracket for easier transport, which is a major advantage for cargo bike riders who don’t want to carry the lock in a bag.
The lock is built for durability with a dust cover to keep the cylinder clean. It isn’t for a user who needs a long shackle to reach around thick obstacles, as the standard size has a more limited interior clearance.
Good if:
- You want a proven, heavy-duty U-lock design.
- You need an included frame mount for easy transport.
- You want a lock that’s pick and drill resistant.
Skip it if:
- You need extra reach for locking to wide posts.
- You prefer the flexibility of a chain lock.
6. Kryptonite 1016 Evolution 9.7 Pound Integrated Bike Chain
Best for: Someone who wants a long-reach chain with an integrated locking head.
This 5.25-foot chain offers great versatility for securing a cargo bike, especially if you need to lock the frame and wheels together. The 10mm six-sided links provide a strong balance between weight and security.
The integrated design means you don’t have to carry a separate heavy padlock, which simplifies the process. It isn’t for a rider who wants the absolute highest level of protection against power tools, as the chain links are thinner than the “Fahgettaboudit” model.
Good if:
- You need significant length to lock your bike.
- You prefer an integrated chain and lock system.
- You want a weather-resistant sleeve to protect your bike frame.
Skip it if:
- You require the highest possible security rating for high-risk areas.
- You want a lighter, more portable lock.
7. Seatylock FoldyLock Compact Lightweight Patented Folding Bike Lock 33.5
Best for: A rider who values portability and a neat, rattle-free storage solution.
This folding lock is designed to be lightweight and compact, making it easy to store on the bike frame without adding bulk. It opens to a 33.5-inch circumference, which is enough for most standard locking situations.
While it’s strong, its folding design means it may not match the raw cut resistance of a heavy-duty chain or a thick U-lock. It isn’t for a rider who is leaving their bike in a high-theft area for long periods overnight.
Good if:
- You want a lock that folds up neatly on your frame.
- You need a lightweight option for your daily commute.
- You prefer a lock that includes a rattle-free mounting bracket.
Skip it if:
- You need maximum security for overnight parking.
- You want a lock that reaches around very thick poles.
8. Kryptonite Evolution 1090 Bike Chain Lock
Best for: Someone who wants a balanced, mid-range security chain for urban use.
This 3-foot chain provides a good balance between weight and security, making it versatile for city riding. The 10mm links are hardened steel, and it carries a Sold Secure Gold rating, which is suitable for most urban environments.
It’s a great all-arounder, but it lacks the extreme link thickness of the heavier chains. It isn’t for a rider who needs to lock their bike to multiple wide objects at once, given its 3-foot length.
Good if:
- You want a balance of weight and security.
- You need a lock for university campuses or city errands.
- You want the financial protection offered by the ATPO program.
Skip it if:
- You need a very long chain for awkward locking spots.
- You require maximum security for high-risk, overnight parking.
9. Kryptonite Kryptolok Standard Bike U-Lock
Best for: A rider who wants a versatile U-lock that includes a cable for extra reach.
The U-lock provides the main security, while the 4-foot cable allows you to secure your front wheel or accessories easily. It’s a solid, commuter-friendly choice that’s easy to carry thanks to the included frame bracket.
The 12.7mm shackle is strong, but not as thick as the New York series, meaning it’s better for moderate-risk areas. It isn’t for a rider who needs to leave their bike in a high-risk area for long periods.
Good if:
- You want a U-lock that includes an accessory cable.
- You need a mounting bracket for easy carrying.
- You want a reliable lock for everyday commuting.
Skip it if:
- You’re parking in very high-theft, high-risk areas.
- You need a lock with the thickest possible shackle.
10. Kryptonite Keeper 785 Bike Chain Lock
Best for: A rider who wants a simple, lightweight chain lock for moderate security.
The 7mm links provide a basic level of protection for quick stops or low-risk areas. It’s easy to handle and comes with a protective sleeve, making it a good choice for someone who doesn’t want to wrestle with a heavy, thick chain.
Because of its lower security rating, it isn’t for someone who needs to leave a high-value e-bike or cargo bike unattended in a city center for a long time. It’s best used as a secondary lock or for short stops.
Good if:
- You want a lightweight chain that’s easy to carry.
- You need a simple lock for errands.
- You want the benefit of Kryptonite’s customer support.
Skip it if:
- You’re parking in a high-theft urban area.
- You need the highest security rating for a cargo bike.
Where These Overlap
Most of these locks share similar design goals, such as using hardened steel and pick-resistant cylinders. The Kryptonite models, specifically the Evolution and New York series, offer overlapping benefits like the ATPO program and durable weather-resistant sleeves. The choice often comes down to the specific weight and length requirements of your bike. If you’re choosing between the Kryptonite 1016 Evolution and the Evolution 1090, the main difference is the length and the specific locking head design; both are excellent mid-range security options.
Still Not Sure?
Do I need a chain or a U-lock for my cargo bike?
If you park in tight city spaces where you only lock to standard racks, a U-lock like the Kryptonite New York Standard is often easier to carry. If you need to lock to trees, poles, or wide posts, a chain like the KOHLBURG Heavy Duty Chain is much more flexible.
How much weight is too much to carry?
If you’re commuting every day, a lock over 10 pounds like the Kryptonite New York Fahgettaboudit can become a burden. If you have a dedicated box or rack on your cargo bike to carry it, the weight matters less. If you need something lighter, try the Seatylock FoldyLock Compact.
What is the biggest mistake I can make when buying a lock?
Always measure where you usually park. If you need maximum reach, the Kryptonite 1016 Evolution is a reliable choice that ensures you can always find a secure spot.
Cargo bikes are often left in public, so following the Sold Secure certification guidelines can help you choose a lock that meets the security standards required by many insurance policies.

Frequently Asked Questions
Do I need to replace my keys if they’re lost?
If you lose your keys, you should contact the manufacturer immediately. Kryptonite offers a Key Safe program that allows you to order replacements if you have registered your key code. Keeping your key code in a safe place is essential for this process.
Would a more capable lock have been a better choice?
If you move to a higher-risk area or buy a more expensive bike, your current lock may no longer provide sufficient security. Upgrading to a Sold Secure Diamond-rated lock, such as the Hiplok D1000, is a common step for riders seeking maximum protection against theft.
