Kids’ mountain bikes generally have wider, knobbier tires and can have front shocks to soften the impact when they’re cruising down rough terrain. Plus, they help the bike be more stable, which leads to fewer spills. The more gears a bike has, the more choice the rider gets in terms of speed and climbing up or going down steep hills.
Our picks for the best mountain bikes for kids are light but tough. They come with reliable brakes, smooth shifting, and legit suspensions that add up to a positive introduction to an active, nature-based hobby.
Best Kids’ Mountain Bikes
The SureStop brake system activates both brakes with one lever, greatly reducing both stopping distance and the odds of your kid going head-over-handlebars on a quick stop, making it perfect for wary starter bikers.
At 21.5 pounds, the frame is lightweight, so kids don’t need to pedal as hard to fly down the trail. This bike also arrives almost completely assembled so even the least handy of parents can get their kid up and riding quickly, with just the handlebar and pedals to install. If you have an accident-prone kid, this is the bike for them. It’s billed as the safest bike in the world, which isn’t a claim we can verify, but we can tell you that it’s loaded with features designed to keep kids safe no matter what kind of trail they’re on. It’s engineered to have a lower center of gravity, a feature that makes tip-over accidents less likely.
The 24 inch wheel kids' mountain bike is a great all-around choice for beginners, thanks to its lightweight frame and nicely chunky tires.
This kids’ mountain bike has eight speeds, double-butted aluminum handlebars, and mechanical disc brakes. It’s suitable for riders 4’8″ to 5’6″ tall. And yes, it’s an investment, but on the flip side, it won’t fall apart.
This mountain bike was specifically designed for younger kids who want to transition from more juvenile BMX bikes to a multi-speed bike like this one with larger wheels.
The twist shifter is easy for beginners to master, and two types of brakes—Nexus Inter3 with coaster hub as well as front and rear v-brakes—give parents peace of mind. You can get this bike with either 20 inch wheels or 24 inch wheels, depending on your kid’s size and needs. It has seven speeds, single-wall aluminum rims, and large tires for extra balance and stability.
There are thick tires and then there are the 4-inch bad boys that come standard on this bike, appropriately called a fat bike. Just like a monster truck's tires crush everything that comes in their path, the Oso Niño can roll over whatever comes your kid's way.
It’s not just their size. The tires on this Diamondback mountain bike are low pressure, which means they mold to the terrain and glide more easily on top of snow. This thing also has a steel frame that’s stronger than aluminum and mechanical disc brakes that have plenty of stopping power. There are seven gears and disc brakes built on a solid steel frame. However, the steel frame is way heavier than aluminum options, and it might be harder for smaller kids to propel and control.
This single-speed Raleigh mountain bike couldn't be easier to ride, so it's a great choice for older kids who are learning to ride who want to tackle trails once they get the hang of things. It has 2.125-inch tires for a smooth ride over rough terrain, a low standover frame, and soft PVC grips that make longer rides super comfortable.
Think of it as a mini bike for kids: The low standover frame means it’s easy to mount and dismount this ride, and the lack of gears means that kids still nervous about riding won’t have to worry about shifting. The twisting shifter makes it easy to change gears , and the styling looks like an adult mountain bike in a smaller package. It’s worth noting that we don’t love the neon frame, and the downside of a single-speed bike is that getting up hills can be tricky. Save this one for flat rides.
We like that this mountain bike includes both a rear coaster brake and a front caliper brake, which helps kids transition to a hands-only brake when they're older.
You may be looking for the best entry level mountain bike, especially if you aren’t sure if your kid will get into the sport—if so, this is a solid option for a beginner whose parents don’t want to throw down a ton of cash. This bike is easy to ride and has an adjustable saddle and a slack seat-tube angle that let the bike to grow with your child. It was specifically designed to wobble less, and make kids six and up feel more confident and in control. The bikes range in size from 12 to 20 inch wheels.
