Master Lock Cable Lock, Set Your Own Combination Bike Lock, 6 ft. Long, Black, 8122D

The Master Lock Cable Lock offers a combination lock type, which is convenient for kids since it alleviates the need to keep track of keys. Made from braided steel with a vinyl coating, it ensures durability and weather resistance, making it suitable for outdoor use. The cable length of 6 feet is adjustable, providing flexibility to secure different objects, including bicycles.

This can be particularly useful for kids who might struggle with more rigid locks. The lock also features a resettable 4-dial combination, allowing for ease of use and the ability to change the code if needed. However, at 8 x 5.8 x 1.1 inches in size and with a 5/16 inch outside diameter, it may be slightly bulky for smaller kids to handle comfortably.

Additionally, while the braided steel offers strength, the security rating might not be as high as some more robust locks, which could be a concern for higher-value bikes or areas with higher theft rates. Despite these limitations, the Master Lock Cable Lock provides a good balance of security, ease of use, and durability, making it a suitable choice for kids-bike-locks, especially in less risk-prone areas.

NDakter Bike Chain Lock, 5 Digit Combination Heavy Duty Anti Theft Bicycle Chain Lock, 3.2/4.27/5Ft Long Security Resettable Bike Locks for Bike, Bicycle, Scooter, Motorcycle, Door, Gate, Fence

The NDakter Bike Chain Lock offers a secure 5-digit combination lock, which is generally safer than locks with fewer digits. This is ideal for kids who might struggle with managing keys. The lock's zinc alloy cylinder and alloy steel chain provide durability and resistance to tampering, although no lock is entirely theft-proof. The chain is wrapped in a scratch-proof polypropylene fabric that protects the bike's frame and extends the lock's lifespan.

The lock is conveniently keyless, allowing kids to set their own codes from 10,000 combinations, reducing the risk of losing keys. At 3.2 feet long and weighing around 1.5 pounds, it is substantial enough to lock multiple bikes or secure a bike to various objects, albeit potentially cumbersome for younger children to handle. The lock's diameter may not fit through smaller wheel gaps of scooters or e-bikes, but it can still secure them by wrapping around.

It’s a versatile lock suited for bikes, scooters, and more, with a good balance of security and ease of use, making it a strong choice for kids' bike locks. Parents should be aware of its weight and size, which might be difficult for smaller children to manage independently.

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

The Via Velo Heavy Duty Bicycle U-Lock with a cable is a robust choice for securing kids' bikes. It features a 14mm U-shackle and a 10mm x 1.8m cable, both made from hardened steel, which ensures strong cut and impact resistance. The lock is Sold Secure Bronze certified, indicating dependable security for short trips and quick stops but may not be adequate for high-risk areas.

The hexagonal PVC cover provides excellent durability against harsh weather, protecting the lock from water, dust, and dirt, which is great for all-weather use. The U-lock's dimensions (7.68 x 4.56 inches interior) offer a snug fit for most bike frames, though the cable is designed to secure wheels and accessories rather than the bike frame itself. Weighing 3.04 pounds, it’s relatively lightweight for portability without compromising on sturdiness. However, the mounting bracket may not fit larger bike tubes such as those found on fat tire bikes, which limits its use for some bike types.

The inclusion of two keys ensures a backup if one is lost, and its ease of use with a pin tumbler locking system makes it accessible for kids. With a high customer rating of 4.5 stars and a ranking of #3 in Bike U-Locks, it's clearly a popular and reliable choice. Parents should consider the security level and bracket compatibility based on their child's biking environment and bike type.

Buying Guide for the Best Kids Bike Locks

Choosing the right bike lock for your child's bike is crucial to ensure their bike remains safe and secure when not in use. There are various types of bike locks available, each with different features and levels of security. Understanding these features will help you make an informed decision that best suits your child's needs and the environment in which the bike will be stored.
Lock TypeBike locks come in several types, including U-locks, chain locks, cable locks, and folding locks. U-locks are generally the most secure, offering strong resistance against cutting and prying. Chain locks are also robust but can be heavy. Cable locks are lighter and more flexible but offer less security. Folding locks provide a balance between security and portability. Consider where your child will be locking their bike and choose a type that offers the right balance of security and convenience.
MaterialThe material of the lock is important for its durability and security. Hardened steel is commonly used in high-security locks because it is difficult to cut through. Other materials like titanium can offer similar strength with less weight. For kids, a lock made from durable yet lightweight materials can be easier to handle while still providing adequate security.
SizeThe size of the lock should be appropriate for the bike and the objects it will be secured to. A lock that is too small may not fit around larger bike frames or fixed objects like bike racks. Conversely, a lock that is too large can be cumbersome for a child to carry. Measure the bike and typical locking locations to choose a lock size that is practical and easy for your child to use.
WeightWeight is an important consideration, especially for kids. Heavy locks can be difficult for children to carry and manage. Look for locks that offer a good balance between security and weight. Lightweight locks are easier for kids to handle but ensure they still provide adequate protection against theft.
Ease of UseA lock that is easy to use will encourage your child to use it consistently. Look for locks with simple mechanisms that are easy for small hands to operate. Combination locks can be easier for kids to manage than key locks, as they don't have to worry about losing a key. Ensure the lock mechanism is smooth and reliable to avoid frustration.
Security RatingMany locks come with a security rating that indicates their level of protection. Higher-rated locks offer better security but may be heavier or more expensive. Consider the environment where the bike will be stored—high-risk areas may require a higher security rating, while lower-risk areas might be fine with a moderate rating. Choose a lock with a security rating that matches the level of risk in your area.
