10 Best Kids Bike Locks 2025 in the United States

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.

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.

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.
