How To Choose The Best Mountain Bikes for Kids

Similar to the best mountain bikes on a budget, the best mountain bike for kids also have some features that you really need to pay attention to, which are:

Wheel size

The first thing that you should check out is the wheel size. Although the specs are great, the bike that you want is basically useless if it’s too high or low for your kid. So, you should make sure that the one that you want to buy matches your kid’s height. Below is a size guide that you can use when choosing the best mountain bike for children.

Bike WheelChild Height (inches)Approximated Age
12-inch30-392-4
14-inch37-443-5
16-inch39-485-8
20-inch42-526-10
24-inch50-588-12

Brakes

When it comes to brakes, it’s no secret that hydraulic disc brakes are more powerful. It means the lever doesn’t need to be pulled as hard to achieve maximum stopping power. It’s also very important that brake levels have a useable reach adjustment so the lever blade can be moved close enough to the bar to better suit smaller hands.

Gears

Unless your kid is strictly riding on the flat, gears are a must. To keep things simple and reliable for kids, we recommend sticking to a single ring up front matched with an 8, 9, or 10 speed set up at the back. Wide range cassettes that offer a really low gear are great for climbing to the trailhead and preserving energy for long days in the woods.

Suspension

Although less common, some mountain bikes have no suspension. It’s fine for beginners on gentle trails, but your kid will have to sacrifice comfort. Meanwhile, hardtail bikes have suspension on the front forks only that brings down the cost as well as the weight. They’re good for cross-country, trail riding, and some all-mountain tracks. Lastly, there are full-suspension bikes that are great for downhill racing or all-mountain riding. Thankfully, there are many options for kids that have a full-suspension system.

Weight

Obviously, the best mountain bike for kids shouldn’t be too heavy. Having a lightweight bike isn’t only easier to pick up, but it’ll also be way more maneuverable when cornering and conquering obstacles. It’ll be easier to pedal around too, which means your kid won’t have to spend so much energy to keep the bike rolling.

What size bike is good for 10 years old?

Most 10-year-olds will fit on a 24-inch wheel bike. However, keep in mind that if your 10-year-old is smaller, they may still be more comfortable with a 20-inch wheel bike.

Roadmaster Granite Peak Mountain Bike

13

The first model we have on this list is the Roadmaster Granite Peak Mountain Bike. If all you want is a cheap, simple mountain bike for children, then this is the go-to bike. Many parents love this bike because, well, it’s super cheap! But just like some of the best bike helmets and best dirt bike helmets specifically designed for kids, cheap stuff doesn’t always mean that it’s bad. You’ll definitely love this bike even more if your kid only rides this mountain bike once in a blue moon. However, note that everything about this bike is decent, and they’re surely not for serious junior riders.  

Made for both boys and girls, this mountain bike is lightweight and pretty easy to navigate. That’s because it features an aluminum alloy frame that’s sturdy and durable. The alloy rims also offer added durability and stability without extra added weight. Meanwhile, the knobby tire treads provide plenty of security on pavement or dirt roads. However, we don’t recommend tackling rough terrains with this bike.

What We Love

A very cheap option for kids that are curious about mountain biking but won’t be doing it very often.

Pros:

  • Super affordable
  • Easy and quick setup
  • Smooth suspension fork
  • Lightweight and sturdy aluminum frame
