How to Choose a Bike Lock

To successfully select amongst the best bike locks of 2020, you need to pick one that’s easy enough to use regularly and secure enough to protect your bicycle. When making your choice, emphasis should be placed on the following:

  • Required level of security

  • Type of lock

  • Brand name 

Choosing the Required Level of Security

Ultimately, the lock’s job is to prevent your bike from being stolen. To effectively protect your bike, it needs to provide you with an appropriate level of security. So, to choose the right strength, you’ll need to consider:

  • Where you live

  • Does your bike attract attention

  • How long is your bicycle left unattended

Type of Lock

There are four types of locks to choose from: cable, folding, chain, and U-locks. Choosing one that provides a reasonable balance between security, weight, and practicality is essential. Although your choice will depend on your unique circumstances, it shouldn’t:

  • Be too small or heavy

  • Be difficult to carry

  • Be complicated to secure

  • Limit the places where you can lock your bike

Brand Name

After determining your required level of security and the type of lock you’ll need, your final step will be to decide which brand suits you best. There are various manufacturers on the market. Via Velo, for instance, produces some good quality fasteners, whereas Litelok, Hiplok, and Foldylock have some outstanding innovations.

Review of the Best Bike Locks of 2021

On a positive note, bike thieves tend to be criminals of opportunity.  If you intelligently secure your bicycle with a high-quality fastener, you can significantly reduce your risk of theft. Let’s take a closer look at ten of the best bike locks of 2020.

Best Overall:
Via Velo Heavy Duty Bicycle U-Lock

Bike U Lock with Cable - Via Velo Bike Lock Heavy Duty Bicycle U-Lock,14mm Shackle and 10mm x1.8m Cable with Mounting Bracket for Road Bike Mountain Bike Electric Bike Folding Bike


  • Three-year warranty
  • Comes with two keys
  • Double-locking mechanism
  • Requires power tools to defeat
  • Durable, all-weather protection


  • Small size isn’t versatile
  • Length of the mounting bolts are inadequate for a thick bike frame

What Recent Buyers Report

Consumers who recently purchased this product claim that it’s incredible. It offers exceptional strength and reliability at a very reasonable price. The bike U-lock with cable isn’t too heavy, and it’s easy to fit on the bicycle frame. As an added incentive, Via Velo adds two keys and provides its clients with an easy replacement option through its keyguard registration service.

The company also offers its customers exceptional customer service. They’re typically quick to reply and provide their clients with complete and useful answers.

Why it Stands Out to Us

The Via Velo 2-in-1 bike lock protects your bicycle with robust security in all weather conditions, regardless of where you are. It comes with a 5 ft 10 in (1.8 m) woven steel cable, a 0.55 in (14mm) U-lock that has a pull-, drill-, and pick-resistant double-bolt locking mechanism, bringing performance and convenience together.

Included in the package are two specialized keys, intricately designed to make copying more difficult. The convenient mounting bracket guarantees compact and safe storage when cycling, eliminating the need for a knapsack or carry case.  

Additionally, the debris cover keeps your lock free of dust and dirt and the PVC protective coating protects your bike against scratches. This product is also dirt-, dust-, and water-resistant, which prolongs its lifespan.

Bottom Line

The Via Velo U-lock provides you with excellent all-weather protection that takes power tools to defeat. It comes with two keys and its double-locking mechanism ensures that any thief will have a hard time picking the lock. What’s more, with a three-year warranty, you can’t go wrong.

Kryptonite Evolution Mini-7

Kryptonite Evolution 11-14mm U-Lock with FlexFrame-U Bracket


  • Lifetime warranty
  • Can be used in almost any location
  • Double-deadlock design guarantees maximum security
  • Equipped with a sliding dust cover to resist dust and debris 
  • 13mm hardened steel shackle withstands both leverage attack and bolt cutters


  • Lock’s plastic cover peels away easily
  • A bit bulky, preventing it from fitting well in specific bike racks

What Recent Buyers Report

According to various users, the mounting hardware is simple to install and allows for installation in different positions. They also claim that the lock is sturdy. Unfortunately, most users state that the locking mechanism is difficult to operate, as the keys are gritty and they’re not easy to insert and turn.

Why it Stands Out to Us

The Mini-7 is a max-performance hardened steel shackle U-lock capable of withstanding leverage attacks and all bolt cutters. It comes with three keys, including a LED replaceable key fob. Its “pass-thru” crossbar design incorporates enhanced anti-rotation, increasing protection against single cut and twist style attacks. 

The Mini-7 features higher security, a drill- and pick-resistant disc-style cylinder, and hardened double deadbolts that engage both shackles ends, maximizing holding power. It also comes equipped with a sliding dust cover and a flexframe u-bracket for multi-location lock storage.

Additionally, with their key safe program, Kryptonite will ship your first two keys for free. The company also offers consumers a 12-month and up to $2,500 reimbursement should their bike get stolen and a lifetime warranty on the product.

Bottom Line

Kryptonite’s Mini-7 U-lock provides you with superb all-around security that can only be defeated by power tools. It comes standard with three keys and a locking mechanism that’s both drill- and pick-resistant. The product's lifetime warranty and the company’s reimbursement program make this an outstanding option. 

Best for the Money:
NDakter Bike Lock

NDakter Bike Lock Cable,4 Feet High Security 5 Digit Resettable Combination Coiling Bike Cable Lock,Bicycle Cable Lock for Bicycle Outdoors, 1.2mx12mm


  • Secure and resettable combination lock
  • Comes with a self-coiling and mounting bracket
  • Braided steel and PVC coating available in various colors
  • Quick installation button for convenient installation and removal 
  • Multipurpose four-foot cable capable of locking two to three bikes together


  • No money-back guarantee
  • Ensure size compatibility is adequate before buying

What Recent Buyers Report

Most user reviews state that the keyless system works great. The Ndakter bike lock chain is well-made and the combination is easy to reset. Consumers also claim that this product is a perfect size, the mounting hardware works exceptionally well, and the color variance is a nice addition. 

Why it Stands Out to Us

The Ndakter cable lock is made with a ½ inch thick, four-foot long braided steel cable, making it ideal to secure your bike's wheels and frame (or multiple bicycles) in low-risk settings. It’s coated with vinyl PVC, enabling it to resist rain and preventing scratching. What’s more, the lightweight mounting bracket and self-coiling design make it convenient to transport. 

The Ndakter bike cable features a five-digit resettable combination lock, providing users with 100,000 code possibilities and eliminating the use of keys. It’s also available in various colors, complementing your bicycle frame.  

Even though this lock is a budget-friendly option and doesn't have many features, the overall protection isn’t compromised. 

Bottom Line

If you’re looking for an inexpensive locking mechanism that’ll provide you with reliability and enough protection for low-risk environments, the Ndakter cable lock may be the ideal choice for you. It’s simple to use and exceptionally efficient. Once it’s installed, you can rest assured that any thief will have a hard time trying to steal your bike. 

Best Cheap Bike Lock:
Master Lock 8143D

Master Lock 8143D Bike Lock Cable with Combination


  • Well-priced bike lock
  • Helps to deter thieves
  • Keyless convenience with a four-digit combination lock
  • Versatile - can be used to secure objects other than bikes as well
  • Comes with a protective vinyl coating, protecting your bike against scratches and scrapes


  • Lock tends to get jammed
  • Not exceptionally sturdy and can be cut down easily using bolt cutters

What Recent Buyers Report

In general, consumers agree that the 8143D is an economic and reasonably durable lock for securing your bike in a public place for short periods. However, the cable isn’t thick enough to discourage determined thieves, and locking down your bicycle overnight, or in high-risk areas, with this product isn’t advised.

Why it Stands Out to Us

Master Lock 8143D is one of the cheapest protection options available. However, it’s best suited as a theft deterrent and for basic security. It provides you with keyless convenience through a four-digit combination lock, and it’s made of a 5/16 inch, four-foot self-coiling, braided steel cable for strength and flexibility. 

The cable itself is covered with a protective vinyl coating, preventing scratches and scrapes on your bike's wheel and frame when attaching and removing it. 

The product isn't as robust as other similar locks, it can easily be cut, and the chain may be a bit short for some locking situations. Therefore, it should only be used as a deterrent. It’s, however, the best option to discourage casual thieves if you’re on a strict budget. 

Bottom Line

Being exceptionally reasonably priced makes this preset combination lock well worth the expense. Its braided steel cable, covered with a scratch-resistant vinyl coating, acts as an effective deterrent for would-be thieves. Overall, this lock does an excellent job of providing basic security. 

Best Lightweight Bike Lock:
Allnice ET-152

Allnice ET-152 Mini Portable Anti-Theft Resettable 3 Digit Bike Bicycle Cycling Spring Combination Cable Lock Senior Travel Luggage Locks Helmet Lock, 4mmx 1500mm (Black)


  • Quite portable
  • Highly resistant to corrosion
  • Durable and strong construction
  • Made from high-quality PVC material
  • The lightweight and spring design makes it convenient to carry around


  • Coiled cable tends to get stretched over time
  • Not suitable for prolonged periods of protection

What Recent Buyers Report

People who recently purchased the Allnice ET-152 tend to agree that it’s an inexpensive, lightweight lock that’s easy to use and set up. They also state that this product doesn’t weigh them down while cycling and easily fits into a road bike jersey. However, it’s not heavy-duty enough to stop determined thieves.

Why it Stands Out to Us

If you’re looking for an effective, easy to use bike lock for short periods, the Allnice ET-152 is a great choice. Being one of the best quality locking mechanisms on the market, it’s made from a 1.5 m long spring coil zinc alloy cable (2 mm inner wire) that’s covered with a high-quality PVC coating, making it scratch resistant. The lock is a resettable three-digit keyless combination mechanism.

If you’re looking for an adjustable, lightweight combo fastener, then this product would be ideal for you. It’s inexpensive, easy to use, and convenient to transport, making it perfect for short-term security. You can also use it to secure valued parts and accessories to your bicycle. 

However, it won’t hold up a good thief for long and it’s not robust enough to withstand tool attacks. 

Bottom Line

The Allnice ET-152 is an outstanding lock for use in short-term storage scenarios. It weighs only four ounces and it’s small enough to easily carry around without being weighed down. This convenience makes it the ideal choice if you’re leaving your bicycle unattended for only a few minutes at a time.

Best Bike Cable Lock:
Titanker Bike Lock

Titanker Bike Lock Cable, 4-Feet Bike Cable Basic Self Coiling Resettable Combination Cable Bike Locks with Complimentary Mounting Bracket, 4 Feet x 1/2 Inch


  • Easy to reset
  • Long, versatile cable lock
  • High-strength braided steel cable
  • Self-coiling without being overly resistant and stiff
  • PVC-coated for the prevention of scratches and rust


  • PVC might be overwhelming
  • Lock and cable attachment isn’t very durable

What Recent Buyers Report

Most consumers claim that the lock is big and sturdy enough to do the job, yet small enough to not be a nuisance. The bracket accompanying the product allows for safe storage when not in use, and the cable is the ideal length for securing your bike to a rack or pole or securing the front tire to the frame. It’s also stated that the combination digits rotates freely and without play. 

Why it Stands Out to Us

The Titanker bike cable lock provides consumers with an excellent balance between security, convenience, and affordability. This multipurpose locking mechanism is four feet in length, ½ inch diameter, and weighs 1.15 pounds. The product's versatility allows it to be used to secure bicycles, gardening equipment, and many other items in a wide range of settings.

The self-coiling cable is small and easily portable when not in use, and it comes standard with a mounting bracket for your bike. It’s manufactured from flexible high-strength braided steel and covered with a durable PVC coating, preventing it from causing damage and scratches.

The four-digit combination lock provides users with keyless convenience through a visible, high-contrast dial that’s easily reset to your own desired sequence. Additionally, it comes with a quick-release button, making it straightforward to use.

Bottom Line

The Titanker cable lock is a self-coiling, resettable mechanism enabling it to be bent into various shapes and allowing you to reset it as many times as you like. Even if you don’t have a bicycle, you can still use it to fasten a broad range of other equipment. All-in-all, it provides you with outstanding cost-effective protection. 

Best Bike U Lock:

SIGTUNA Bike locks - 16mm Heavy Duty U Lock with U-Lock Shackle and Bicycle Lock Mount Holder + 1200mm Steel Chain Cable Bike Lock


  • Enhanced cylinder
  • Three-year warranty
  • Comes with three keys
  • Double deadbolt results in extra security
  • Heavy-duty design provides robust security


  • A bit more expensive than other U-locks
  • Weighs more than other similar products

What Recent Buyers Report

Various recent buyers state that the Sigtuna bike lock is well worth its price. Although it may be a bit cumbersome, the mounting bracket allows for easy storage and removal through the push of a button, making this product more manageable. They also claim that the 16 mm steel U-lock is large enough to secure your bicycle to a railing or post without the use of the cable. 

Why it Stands Out to Us

The Sigtuna bike fastener is only available in a combination of silver and black and comes as a 16mm heavy-duty U-lock that’s accompanied by an enhanced shackle and a 12 mm steel woven cable, making it ideal even for foldable bicycles. The lock’s rubber coating and the flex cable’s plastic PVC cover prevents rust and makes the product weatherproof.

As a product of the USA, the Sigtuna fastener features high-performance steel capable of resisting any jacking, prying, or pulling attacks from potential thieves. It comes standard with three keys and a double-bolt design, resulting in it having to be cut through at both ends to free the bicycle. The 16 mm thick steel shackle ensures that this wouldn’t be an easy task.

Additionally, with a 47-inch long cable, you can conveniently and firmly secure your bike helmet as well. 

Bottom Line

All cycling enthusiasts looking for optimal security features when it comes to securing their bikes should consider the Sigtuna U-lock. Featuring the latest industry standards, it’s a robust, easy to use, and affordable solution for both hobbyists and professional bikers.

Best Folding Bike Lock:
Kryptonite Keeper 510

Kryptonite Keeper Folding Bicycle Lock


  • Ideal for mid-level security needs
  • Two sizes available to fit both bag and bike size
  • Sliding cover to prevent debris and dirt build-up
  • Lightweight and compact, making it easy to carry and store
  • Made from 3 mm hardened steel to ensure durability despite its compact size


  • Not suitable for high-risk environments
  • Keys can get sticky and awkward to use at times

What Recent Buyers Report

Most consumers state that the Kryptonite folding lock is good for medium-security and that its compact size makes it easy to securely store in the provided carrier. They also note that the smaller size is large enough to secure the rear wheel and frame, making it the ideal solution for use during the day while shopping or dining.

Why it Stands Out to Us

If you require moderate security, the Kryptonite Keeper 510 is an option you should keep in mind. This folding lock solution is shipped with an easy to install transport bracket, ensuring hassle-free conveyance. It's 1 m in length, making it much more convenient to use than cable, chain, or U-locks, and it features 3 mm hardened steel links for mid-level security lock-up.

The Keeper 510 comes standard with two keys and a dust cover to prevent debris and dust build-up. Although the key can be a bit sticky at times, the lock provides solid protection by easily fitting around the rear wheel and bike frame. 

As it’s a Kryptonite product, you have the opportunity to activate the anti-theft protection offer. This means that the company will reimburse you with a specific amount should your bicycle be stolen while using their product. Additionally, should you lose both your keys, the key safe program registration will ensure that the organization ships your first two replacement keys to you free of charge. 

Bottom Line

The Keeper 510’s compact size and light weight make it the ideal solution for moderate security environments. Its small design, along with its robust protection, makes its cost worth your while and an option all cyclists should consider.

Most Secure Bike Lock:
Sportneer Bicycle Chain Lock

Sportneer Bicycle Chain Lock, 5-Digit Resettable Combination Anti-Theft Bike Locks


  • Well-priced
  • 100% money-back guarantee
  • Versatility allows for multiple locking applications
  • Lightweight, making it easy to carry and transport
  • Five-digit combination pad providing users with a keyless solution


  • Chain isn’t as thick as some other models
  • Initially resetting the lock combination can be tricky

What Recent Buyers Report

Even though several consumers claim that this bicycle chain lock is a bit heavy, they’re satisfied with the quality and agree that it provides robust security. Most also state that the combination is straightforward to reset and the number wheels are easy to read. It’s also mentioned that the padded chain conveniently wraps around the seat post, making it hassle-free to transport. 

Why it Stands Out to Us

The Sportneer bicycle chain lock’s five-digit combination pad provides users with an added layer of security, making it an excellent upgrade from the average four-digit fasteners. This product’s chain is made from 0.27-inch thick manganese steel. Although it’s not the most robust material, the flexible cloth-sleeve covering creates the impression of something more sturdy underneath.

This cover also prevents the chain from rust and your bike’s frame from scratches, ensuring a longer lifespan for both. The total length of the fastener is 3.2 feet, increasing the number of objects you can secure with it, such as gates and toolboxes. Even though the lock is a high-quality product, it’s inadvisable to use it to lock down your bicycle overnight in a bad neighborhood.

Yet, this lock is a favorite amongst cyclists looking for a more affordable solution capable of intimidating thieves during the daytime. 

Bottom Line

If you’re looking for a secure lock on which you can fully rely to protect your bike, the Sportneer bicycle chain cable is an outstanding solution. With 100,000 possible combinations, it provides enough security to discourage most thieves from tampering with your wheels. 

Best Kryptonite Bike Lock:
Kryptonite Keeper 785

Kryptonite Keeper 785 Integrated Bicycle Lock Chain Bike Lock, 33.5-Inch, Black


  • Discreet design
  • Solid chain lock
  • Compatible with Kryptonite D- and U-locks
  • Hardened deadbolt design for extra holding power
  • Durable weather-resistant nylon sleeve available in three colors


  • Keyhole isn’t covered
  • Lock doesn’t provide enough security for high-risk areas on its own 

What Recent Buyers Report

According to various consumers, the Kryptonite Keeper 785 is a formidable-looking lock that acts as an outstanding theft deterrent. They also claim that the heavy-duty locking mechanism is well-tuned, leaving no doubt as to whether it’s locked. Another client also mentioned that the extra key provides you peace of mind in knowing that you’ve got a backup.

Why it Stands Out to Us

The Kryptonite 785 is made from a 7 mm four-sided high performance 3T manganese steel chain, covered with a weather-resistant nylon sleeve to prevent scratching. It’s designed to compactly coil around the bike frame or seat post, ensuring convenient transportation.

This design secures the chain directly to the hardened deadbolt, eliminating the lock’s weak link. It’s fitted with the same disc-style cylinder found in similar Kryptonite products, but, because it's a more cost-effective model, it only comes with two ergonomic keys. However, you’re still eligible to get replacements from the key safe program.

Although Kryptonite is known for manufacturing some of the most solid bike locks, this specific model isn’t suitable for high-crime areas.

Bottom Line

Even though the Keeper 785 doesn’t provide maximum protection, the fastener is well designed, it’s made from high-quality materials, and it’s easy to use and transport. It offers consumers exceptional value for money, making it an option well worth looking into.

Types of Bike Locks 

There are four main types of bike locks available on the market, all tailored to meet different needs. The top three varieties are:

  • D- or U-locks
  • Chain locks
  • Cable locks


U-locks are typically more expensive and heavier than other varieties and usually can’t be defeated without power tools. They make great visual deterrents and provide the most secure solution. High-security models often feature double deadbolts, meaning that any potential thief will need to make two cuts to open it.

Chain Locks

Chain locks are large and durable and can easily be looped around any bicycle. These fasteners feature thick links and heavyweight padlocks, ensuring that any would-be thief will think twice before attempting to break them. These fasteners tend to be extremely tough and provide excellent visual deterrent. Unfortunately, they tend to be heavy and difficult to carry. 

Cable Locks

Cable locks are lightweight fasteners designed for protecting bicycles in low-crime areas. They’re convenient to carry and use and are typically fitted with combination locks, eliminating the risk of losing your keys. It can easily be looped around all types of bicycles, making them uncomplicated to transport. 

However, they provide a poor visual deterrent, the combo lock is less secure, and thieves can effortlessly cut through the cable. 

Comparison Overview

U-Lock vs Cable Lock

Cable locks are the better option when it comes to transportation, weight, flexibility, and storage. Unfortunately, they’re much weaker and provide consumers with poor theft deterrence. They’re easily defeated with bolt cutters, and the combination locks are often figured out in a few minutes.

U-locks, on the other hand, tend to be heavy, but robust fasteners. They make exceptional visual deterrents as thieves will have to use power tools to defeat them as they’re extremely hard and near impossible to open without a key. Unfortunately, they’re often inconvenient to use. 

Photo credit:

Key Lock vs Combination Lock

Many fasteners come with combination locks. If you’ve got a tendency for losing keys, then a combo fastener will be the way to go. Yet, hacking these mechanisms doesn’t pose a problem for experienced thieves. However, key-operated locks can’t be opened without the right key, no matter how much guesswork a criminal does. 

Abus vs Kryptonite

Abus is well known for producing the highest quality and most reliable locks. Their locks are exceptionally well-made, the last longing, and performed exceedingly well under adverse weather conditions. They’re, however, also the most expensive fasteners. 

Although Kryptonite’s locks last a long time, are generally well-made, and perform fairly well under extreme weather conditions, they’re inferior to their Abus counterparts. However, the company’s customer service is unbeatable.

How to Properly Lock a Bike

Regardless of the locking mechanism you’re using, there are a few things to consider when securing your bicycle, these include:

  1. Choose a lock with an appropriate amount of security for your needs and circumstances

  2. Always secure your bicycle to a solid object, ensuring that it can’t be lifted over

  3. Choose a well-lit area with a lot of people 

  4. Be sure that the object you lock your bicycle to can’t be cut

  5. Always secure the most valuable parts first - frame, back wheel, then front wheel, and accessories

  6. Make sure to get a tight fit, leaving as little room as possible within the lock

  7. Always position the lock off of the ground, with the locking mechanism facing downward

Some of the most common methods for securing your bike include:

  • Frame-only lock-up
  • Securing the frame and rear wheel
  • Lock down the frame and both wheels
  • Two U-locks method 

Please feel free to refer to the video below for a comprehensive overview of these methods.

Bike Lock Tips, Tricks, and Hacks for Success

Frame Only Lock-Up

Many instances allow you to secure only part of your bicycle, due to your bike size, lock size, or oddly shaped structure. In this scenario, ensuring that the frame is secure should take priority.

Securing the Frame and Rear Wheel

This is a much better option as you’ll be able to capture the immovable object, rear-wheel, and frame with a single lock.

Lock Down the Frame and Both Wheels

Being one of the most popular methods for securing bicycles, it allows you to capture the immovable object, rear-wheel, and frame with a U-lock and use it as an anchor to lock down the front wheel using a double-looped cable.

Two U-Locks Method

This solution provides the most effective protection. Use a U-lock to secure the rear wheel and frame to an immovable object and a second U-lock to fasten the front wheel to the frame.

When choosing a bike lock, you must choose the correct level of security, type of fastener, and brand. Remember, combination locks aren’t as robust as key-operated ones, and cable fasteners are much weaker than U-locks.

It’s also vital to learn how to properly secure your bike with the lock of your choice. Improper use is often only slightly better than not locking down your bicycle at all. 

People Also Ask

After reading an article like this, people often have several unanswered questions. The most frequently asked ones are resolved below.

Are Any Bike Locks Theft Proof?

Regardless of what you might've been told, there's no such thing as a theft-proof bike lock. Although some fasteners are more robust than others, they’re all breakable. The most durable ones do, however, act as an effective deterrent to would-be thieves, but they’re typically more expensive and heavier.

Where Should You Store Your Bike Lock While Riding?

Bike locks usually come with a mounting bracket, specifically designed for transport convenience. These mounts are useful for storing your fastener while riding. If using these brackets aren’t an option, you can put the lock in your backpack or leave it at your destination.

Is There a Bike Lock That Can’t Be Cut?

There are various chains and U-locks available that can’t be cut through with bolt cutters. However, a determined thief equipped with an angle grinder and given enough time can sever almost any lock.

Should I Use Two Bike Locks?

If you have to secure your bike in a high-risk environment, using two locks, preferably U-locks, is advisable. Utilizing the first mechanism to secure your frame and rear wheel and the second to fasten the front to the bicycle frame will provide you with the most effective protection.

How Do You Break a Bike Lock Without a Tool?

The most uncomplicated way to jimmy a U-lock is by using a ballpoint pen. This process is explained in brief below:

  • Find a standard ballpoint pen
  • Remove the cap from the rear end
  • Insert the pen’s tube into the mechanism’s keyhole
  • Push and twist the tube inside the keyhole until the U-lock unlocks
  • Remove the top bar of the mechanism

How Much is a Bike Lock?

Bike locks vary greatly in price depending on the quality, brand, and type of mechanism. However, the cheapest fasteners start at about $7.64 for the Master Lock 8143D, while the most expensive ones can be as much as $185.95 for the Kryptonite New York Fahgettaboudit 1415. 

When Did Kryptonite Come Out?

Kryptonite was established in 1971 after the entrepreneur Michael Zane read about Stan Kaplan’s U-lock invention. The two entered into a partnership with Zane subsequently traveling across the US to spread the message of the growing need for bike security.
