The Best Kid-Friendly Bike Locks

The 5 Best Bike Locks for Kids

Reader question: Can you recommend a bike lock for my 7 year old?  He rides a few blocks to school, and I want him to be able to lock (and unlock) his bike on his own.

What a tricky question!  The safest bicycle locks are heavy and bulky—not ideal for a child.  On the flip side, easy-to-carry, lightweight locks are easy for thieves to cut.  I’ve tried to balance these two factors – portability and weight – when compiling my favorite kid-friendly bike locks.  That said, I’ve put an emphasis on weight and easy operation; if your child’s school isn’t in a safe area, or if you are looking for a lock for family bike rides, consider a U-Lock instead.

Cable locks aren’t as secure as U-locks or chain locks, but they are light and easy to carry.  If your child is locking up their bike in pretty secure areas, or they are too young to carry a heavier lock, this is a fun one.

Wordlock Kids Bike Lock

I had to include this one because it is just too cute.  Words can be easier for young kids to remember than numbers, but I do worry that it is probably easier for a would-be thief to figure out a word also.  Nonetheless, if you are just looking for a lock for the school bike park, this will probably do the job.

This bike lock looks just like hand-cuffs, and functions the same way.  Kids love it, and you can’t count on them locking as many wrists as bikes with this thing.  It’s also one of the toughest locks out there.  Unfortunately, it’s also one of the heaviest, so save this one for older, stronger kids.

There are a couple of things to consider when choosing the best lock for your child and their particular situation.  If you have two kids biking to school together, you might want a lock that is long enough for two bikes.  If you have an older child who can handle a heavier lock, choose the one with the best security (The Master Lock Street Cuffs).  If you have a kindergartner, go with the lightest lock you can find.
