If there’s one factor in a kids bike that’s more important than all others, it’s bike weight. It makes the biggest difference and is worth every extra dollar you spend.

For years, we bought our kids nice bikes, but never focused on weight. It wasn’t until we were shopping for a little 12″ bike for my 3-year-old that I realized that all of these tiny bikes weighed as much as my adult bike, and many of them weighed more than he did. Since then, we’ve been on a quest to find the lightest bikes we can for our kids while still not breaking the bank.

The effort to get our kids lightweight bikes has paid off immensely. Not only have lightweight kids bikes allowed our kids to ride longer, and get less tired, but it’s also enabled them to have the strength to try more technical features on mountain bike trails.

Since getting our kids lightweight bikes, our teens have gotten into mountain bike racing (it’s so much easier on a bike that’s 23 pounds instead of 35 pounds), and our younger kids have become just as comfortable biking everywhere as they are with walking!

Shopping for lightweight kids bikes can be confusing and frustrating for most parents because the options seem endless. As we know, the world of kids’ bikes has been turned upside down in the past decade. Training wheels are out, balance bikes are in. And even basic bikes have evolved to make riding easier to learn, more fun, and safer.

Since your child will be on the bike often, you want to make sure you choose an option that is safe and durable. Some brands of lightweight kids’ bikes are much better than others. 

In this post, we review some of the best lightweight bikes for kids, so you can make the best decision for your child.

Why Lightweight Bikes for Kids are Important

An ordinary steel bicycle can be anywhere from 2/3 or more of the bodyweight of the child. Even some aluminum bicycles for kids can be 1/2 of the child’s body weight. Imagine what that feels like when it falls on top of you? Even more, imagine just how hard it is to steer a bike or ride up a hill on a bike that’s that heavy?

The best kids bikes should be lightweight. Because a lightweight bike is safer for kids to ride, not to mention easier to handle.

With a lightweight kids bike, your child can ride longer distances, get on more easily, start faster, can cycle faster and more easily bike up a hill.

For example, the Woom children’s bicycle that’s 16 inches weighs 11.8 lbs (5.7 kg) which makes it one of the best lightweight bikes for kids and allows them to move faster with more confidence. In comparison, we weighed one of the neighbor kids 16″ bikes (from a reputable bike brand), and the bike weighed 28 pounds. The weight difference is SHOCKING!

Lightweight bikes for kids have the regular dimension and geometry of a traditional bike, the’yre just built with lightweight, and often better, components.

Best Brands for Lightweight Kids Bikes

There are several brands that now make lightweight kids bikes, but our personal favorites are Woom and Guardian. Woom is the gold standard for lightweight kids bikes. They function well, are designed perfectly with kids bodies in mind and they can stand up to lots of abuse (we have one on it’s third kid and it’s still in great shape). Woom has bikes that can handle any condition and even lightweight mountain bikes that fit kids up to age 14.

Woom and Guardian bikes on the trail side by side

Guardian is our next favorite brand because they offer lightweight bikes for kids at an affordable price. These are the bikes I recommend for timid or new riders because the sure stop brake system takes all the uncertainty out of braking. The brake system is awesome for the road, though can get tricky on technical dirt trails. Overall, it’s an awesome bike company that provides lightweight ibkes for kids at a very affordable price.

Biky Lightweight Bikes for Kids

Biky Bikes are new to the US market, and we’ve been testing them out for a while. They are the lightest kids bikes we’ve found and the quality is really great.

Biky bikes all have internally routed hand brakes for safe braking and so that kids have more control. We love that this is a standard feature for all of their pedal bikes. Another great feature of Biky bikes is the chain cover. This prevents the chain from getting caught on clothing, getting grease all over clothing and helps preserve the life of the chain.

Biky 14

Cost: $349
Weight: 10.9 pounds
Size: 14″ wheel
Kids Height 37″-43″
Ages: 3-5 years

We love the Biky 14 bike for kids just learning how to bike. It’s the lightest pedal bike we’ve found for kids and that combined with a low stepthrough make it fantastic for kids just learning how to ride a pedal bike. There is also a steering limiter to help prevent kids from overcorrecting and crashing, which is one of the biggest reasons that new riders crash on their bike.

Our almost 3-year-old got this bike and after just a few tries, she had figured out how to ride it, and within a week, she had learned how to fully ride it and start by herself. This did wonders for her confidence! We highly recommend this bike for young kids learning how to ride a bike!

Biky 16

Cost: $399
Weight: 11.9 pounds
Size: 16″ wheel
Kids Height 40-46″
Ages: 4-6 years

Biky 16 kids bike

What immediately stands out about the BIky 16 is its lightweight design- at only 11.9 pounds it makes it very easy for beginners to handle and maneuver. My five-year-old can easily pick this bike up all by herself. The low center bar on the frame is thoughtfully made, allowing even smaller children to get on and off the bike with ease, which is essential during those early learning stages. This feature not only boosts confidence but also enhances safety, minimizing the risk of falls. Moreover, the high-quality materials used in the construction of the Biky 16″ ensure durability and longevity, promising many years of enjoyable rides. Having experienced the benefits of such well-designed features firsthand, I can confidently say that this bike is an excellent choice for any parent looking for their kids a lightweight and durable bike.  

Guardian Lightweight Bikes for Kids

All guardian’s bikes are lightweight with a sure-stop system. The guardian bikes are award-winning in safety for children’s bikes. With any guardian bike, you can be sure that your child is safe no matter the speed or place they are riding. 

Guardians unique Sure Stop braking system is unbelievable and is a game changer for young kids or children who are more timid on their bikes. All of their bike just have 1 hand brake and it controls both front and back brakes. The brakes are designed to sense where your childs weight is so that each brake gets the right amount of pressure so that the tires both stay firmly on the ground. I was skeptical at first, but we’ve put it to the test over and over again, and it’s incredible!

We first were introduced to Guardian bikes 3 years ago when we wre looking for an affordable lightweight bike for our 4-year-old. He was a pretty confident rider, but as he was always trying to keep up with is 4 older siblings, he wasn’t always safety minded. We instantly fell in love with lightweight Guardian bikes for kids. Our son got the safety of the sure stop system, but he was able to fit into a 20″ small bike, and the bigger tires on the smaller frame made it easier to keep up with his older siblings. We recommend Guardian Bikes to everyone with young kids!

Prevelo Kids Lightweight Bikes

prevelo kids bikes

We absolutely LOVE Prevelo bikes, and highly recommend them as a great lightweight bike option for kids.  Prevelo makes both and Alpha and a Zulu line, so that different riders have different options. 

The Prevelo Alpha line is the most lightweight and is designed for neighborhood and street riding.  The bikes are all incredibly lightweight and they have narrower tires to make the bike even lighter (while still being stable).  

prevelo kids bikes

The area where Prevelo really shines is with their kids lightweight mountain bikes.  Our 11-year-old is riding the Prevelo Zulu Five right now and it’s absolutely incredible.  We love that all of the components are designed with kids in mind to help make mountain biking easier and more comfortable for kids.  The kid sized crank and wide range of gearing have made a huge difference in my son’s technical skills as well as his confidence on the trail.  Previously he was riding an adult xs bike and it’s incredible what a difference a kids-engineered bike makes.  The frame fits him better, the components are easier for him to use (meaning he lasts longer out on the trail), and he has so much more control thanks to the shorter chainstay and the frame geometry.  Truthfully, riding a Prevelo Zulu Five has taken his riding to the next level. His shifting has improved thanks to the 1×10 drivetrain with a larger span, the kid-sized cranks, and the fantastic components.

prevelo kids bikes

Of course, his younger brother snuck it out for a few rides, and I was surprised that it fit my petite 9-year-old great as well. Even though the bike looked a little big on him, the geometry and components gave him solid control, so both kids could easily have a gear fit with the same sized bike.  My recommendation would be to get your child into the bigger size as soon as the Prevelo size guide says that they’ll fit.  The advantage of having bigger wheels is always really helpful out on the trail, and since the geometry is so well designed, the Prevelo Zulu mountain bikes don’t feel too big even for kids who are on the smaller side of the fit. If you want to read our full review of the Prevelo Zulu Five read here.

Final Thoughts 

Ideally, a kid’s bike should be less than 40% of their weight. While all kids can benefit from lightweight bikes, a few pounds can make a big difference for young, timid, and beginner riders.

Start your child with a small bike. It helps build confidence when riding.
