Every kid remembers their favorite bike. Years later, you can still recall how the handle bars felt on your palms, how high the seat sat, and the force of wind and gravity, blowing your hair your hair while you stood on the peddles and rode swiftly downhill. When you’re buying a new bike for your child, you’re inspiring the same sort of memories you made with your bike years ago.
Mountain bike manufacturers have gone to greater lengths in the past 10 years to make the sport more accessible to all types of riders—now junior can ride the trails with mom and dad on a bike that’s as good as one for an adult. Believe it or not, there’s even mountain bikes for toddlers, that the little tikes walk along side.
Check out our Buyers’ Guide for the best kids mountain bike below and then take a look at our Top 3 and see of any of these bikes are right for your child.
When you’re buying a mountain bike for yourself, you’ll be considering different things than when you’re buying a bike for your child. Most obviously, there’s a significant size difference. Also, you want to make sure your child’s bike is the safest available.
Safety is a primary concern when buying a bike for a young rider. It’s important to get a bike with hydraulic breaks (thankfully, the industry standard) to insure the bike is going to stop when your rider tells it to stop. Disc breaks are also a feature to keep an eye out for as these will stop the wheels even quicker. Also, until your child rider is confident, make sure they’re wearing a helmet, pads and long sleeves to avoid injuries. Of course, they’re going to fall. Every kid falls off their bike—even you, remember? But when they do fall, you want to make sure they’re safe.
Adjustability is another major concern when buying a child’s bike as opposed to buying a bike for an adult. For the most part, once you find the optimal seat placement on your bike, you leave it set there. For a growing child, however, this is a major concern. You want to make sure the bike is able to grow with its rider. Otherwise, you’ll be buying a new bike for your child every time they have a growth spurt. Sounds expensive!
Lightweight frames are another consideration for a child rider. Think about it, if a bike is 30 pounds, and your child weighs only 70 pounds, the bike is almost half their weight! So finding a light bike for a child is particularly important because they are so small. Aluminum frame bikes are perfect for young riders as these allow for light weight construction with a high quality frame.
Smaller wheels are going to be more common when looking for children’s bikes. If your child is less than 4 feet tall, they want a bike with 20 inch wheels. If they’re more than 4 feet tall, they want a bike with 24 inch wheels. Eventually, they’ll grow into an adult bike. But keep in mind that child riders will go through bikes faster than adult riders will since they’re always getting taller.
Look for bikes with duel-suspension. While a hardtail bike might be more fun for an older (adult) rider, you want a bike that will absorb a lot of the impact of the trails so your young rider doesn’t take the force head on. Dual-suspension bikes are pretty standard on mountain bikes these days so it won’t be too hard to find. The suspension of a bike is one of the main criteria for determining the bike’s quality, so look for that in reviews you read about different models.
Now, we’ve saved the best for last. The best tip we have for parents picking out a mountain bike for kids is this: ignore suggested age ranges! They don’t mean much at all. They’re going on the average height and weight of children at different age markers. Now, I’ve met plenty of children of all different types and weights—but believe it or not, we’ve rarely met a child who is just “average” for their height or weight. Who likes to think of their kid as average? Instead, measure your child. Use your sewing tape and see how long their legs, arms, and torso is. If there’s a store close to your house (Walmart, for example) measure your child on a mountain bike at the store.
That said, when you go to Walmart notice the prices compared to the quality. You’ll get a cheap bike, but if you buy online you’ll pay less money for a much better bike. Since you can buy online direct from manufacturers, you can choose the best bikes to buy (we listed our Top 3 favorite below)

Budget Choice – Kent Super Boys Bike 20 Inch
For around $100, the Kent makes an excellent budget mountain bike for kids. It’s got a 7 speed twist shift gear system. This is just enough to get young riders used to switching gears while riding the bike. It’s got welded, duel-shock suspension—a feature usually not available on a mountain bike in this price range. The duel-shocks are a feature your little rider will love, as they learn to ride the dirt trails and let the bike take the brunt of the shock. The bike is on the heavy side (36 pounds) and will help with balance for little riders. Sitting on 20 inch wheels, the Kent is perfect for small riders who are less than 4 feet tall. It has hydraulic hand breaks, tested for safety. Now, keep in mind, this bike is on the smaller side, so eventually your child will need another bike. Also, reviews have commented that the sturdiness of this bike may vary. Some users report that the bike broke after heavy use, which might be right around the time your little rider has outgrown this bike. However, the combination of price and features still make this a great budget choice—especially since the lowered durability is outweighed by the fact that your child will grow and need a new bike.
Buying a mountain bike for your kid is a fun experience for the whole family. They’ll be creating great memories on their new bike soon after you buy it. When you’re buying, keep in mind safety, adjustability, shock suspension, frame, wheels, and most importantly the height and size of your rider.
