  • The adjustable seat allows you to move the saddle forward and backward with ease, which will help your child avoid knee injuries while riding long distances
  • Not only does the aluminum frame make it lighter but also pretty resistant to scratches and damages

Things to Consider

When your child has outgrown their 12 or 14-inch bicycle, it might be time to consider a 20-inch mountain bike. These bikes are designed for rugged off-road use, with durable parts that can stand up to plenty of abuse.
Of course, there are so many different types of 20-inch mountain bikes out there in the market today, so it might be hard to decide which ones would be best suited for your child. If that’s the case, then not fret! We’ve done our research into finding the best bikes for your child! But if you are still looking for the best 16-inch bikes for your growing child, check our guide for more information.

Things to Consider When Choosing the Best 20-inch Mountain Bike

7 Best 20-Inch Mountain Bikes for Kids – Develop a Great Sense of Adventure in Your Kid! (Spring 2022)

Mountain bikes with a diameter of 20 inches are usually suitable for kids aged between 8 to 10.

Most importantly of all, though, look for a  20-inch mountain bike that fits your child, with good stand-over height (the distance from the top tube down to their crotch) that allows them to comfortably straddle the frame while standing flat-footed on the ground. Fit is more important than a mountain bike’s name brand or popularity with other kids at school, so spend some time making sure your child is comfortable and can easily reach all of their controls before you buy one!

These things are the ease of balancing, the brake system, whether it is for boys or girls, its size and weight. Additionally, it’s quite important to know the best time to buy bikes to save your time and money.

Bike Weight

Mountain bikes, especially the smaller ones, are often quite heavy. This is because they’re designed for off-road use, where the added weight can help to keep them stable on rough terrain. While many 20-inch mountain bikes weigh in at around 30 pounds or more, some lighter models are also available. If your child is young or has trouble with heavier bikes, you might want to consider a lighter option.

Braking System

Most 20-inch mountain bikes come with either V-brakes or disc brakes. V-brakes are the standard brake system for mountain bikes, and they’re usually quite reliable. However, disc brakes offer more stopping power and are less likely to fade in extreme conditions. If your child is going to be using their bike for serious off-road riding, then disc brakes are the best option.

Gearing

7 Best 20-Inch Mountain Bikes for Kids – Develop a Great Sense of Adventure in Your Kid! (Spring 2022)

The 7-speed is adequate for most riders, which is why many people choose the slower option.

The gearing on a 20-inch mountain bike can vary greatly, depending on the model. Some bikes come with a single gear, while others have as many as 10 gears. If your child is just starting out or isn’t planning on doing any serious mountain biking, then a bike with fewer gears will be fine. However, if your child is an experienced rider who wants to take their bike on tougher trails, then they’ll need a bike with more gears.

Handlebar Height

The handlebar height on a 20-inch mountain bike can also vary, depending on the model. Some bikes come with adjustable handlebars, while others have fixed heights. If your child is still growing, then it’s a good idea to choose a bike with adjustable handlebars so they can keep riding it for a few years. If they’re already the right height, then a bike with fixed handlebars will be fine. Also, make sure you measure their inseam to determine a proper fit for a bicycle because there are plenty of bikes out there that give the option to change out handlebars and seats.

Suspension Type

7 Best 20-Inch Mountain Bikes for Kids – Develop a Great Sense of Adventure in Your Kid! (Spring 2022)

A full-suspension mountain bike features both a suspension fork up front and a rear shock, whereas a hardtail bike has only a suspension fork. The type of suspension a mountain bike has will affect the bike’s control, traction, and comfort.

20-inch mountain bikes come with either front or full suspension. Front suspension is more common and is found on most entry-level mountain bikes. It helps to absorb the shock from bumps and obstacles, making the ride more comfortable for the rider. Full suspension is found on more expensive mountain bikes and provides even better shock absorption. If your child is planning on doing a lot of mountain biking, then they’ll need a bike with full suspension.

Frame Material

Most 20-inch mountain bikes are made from either aluminum or steel. Aluminum frames are lighter and more durable than steel, while steel frames are a little heavier but can withstand more abuse. If your child is going to be doing a lot of mountain biking, then an aluminum frame is the best option. If they’re just starting out, or you’re not sure how much riding they’ll be doing, then a steel frame will be fine.

Durability

When choosing a 20-inch mountain bike, it’s important to choose one that’s going to be durable and withstand the abuse of kids. You don’t want to replace the bike every year because it can’t handle the rough treatment. Look for a bike that has a strong frame and high-quality components. If your child is going to be using their bike for everyday riding, then it’s worth spending a little extra money on a bike that’s built to last.

Other Features

There are a few other features to consider when choosing a 20-inch mountain bike. For example, some bikes come with front and rear disc brakes, which provide better stopping power than traditional brakes. Others come with lockout suspension, which allows you to lock out the suspension for climbing or sprinting temporarily. If your child is going to be doing a lot of different types of riding, then it’s a good idea to choose a bike with these features.

Price

The price of a 20-inch mountain bike can vary greatly, depending on the brand and quality of the bike. It’s possible to find a good quality bike for as little as $200, but it’s also possible to spend over $1,000. If your child is just starting out and you’re not sure if they’re going to stick with mountain biking, then it might be a good idea to choose a cheaper model. However, if your child is an experienced rider and you know they’re going to be doing a lot of mountain biking, then it’s worth investing in a higher-quality bike.

Age and Experience

Children grow and develop at different rates, so it’s hard to put an exact age on when a child is ready for a 20-inch mountain bike. Some kids might be ready as young as 8 or 9, while others might not be ready until they’re 11 or 12. The best way to determine if your child is ready is to watch them ride their current bike and see how they handle it. If they’re constantly scraping their knees on the ground or struggling to stay upright, it might be time to move up to a bigger bike. Try one of the best 24-inch mountain bikes to make your child a more experienced rider.

If your child has some experience riding mountain bikes, then they’ll be able to handle a 20-inch model with no problems. However, if they’re just starting out, it might be a good idea to choose a bike that’s a little smaller and easier to control. This will help them build their skills before moving up to a bigger bike.

Girls’ vs. Boys’ 20-Inch Mountain Bikes

There isn’t much difference between girls’ and boys’ 20-inch mountain bikes. The main difference is the color and design of the bike. Girls’ bikes typically have more pink and flowers, while boys’ bikes are more sporty and masculine. Other than that, the specs of the bike are pretty much the same. So, if you’re not sure whether your child is a boy or a girl, then it’s best just to choose a bike that’s unisex.

Safety Tips When Riding on a  20-Inch Mountain Bikes

  1. Always wear a helmet. A helmet is essential for protecting your child’s head in the event of a fall or accident.
  2. Make sure your child wears clothes that are appropriate for riding a bike. Jeans or other baggy clothing can get caught in the spokes or chain, causing the child to fall.
  3. Teach your child the basics of riding a bike before going on a mountain biking trail. This includes how to brake and how to use the gears.
  4. Stay hydrated while riding. Bring along a water bottle and make sure your child drinks plenty of water while riding.
  5. Beware of obstacles and hazards on the trail. Teach your child to be aware of their surroundings and to avoid any obstacles that could cause them to fall.
  6. Never ride alone. Always ride with a friend or family member in case of an accident.
  7. Be respectful of other riders and trail users. Remember, this is a shared space, so please be courteous to others when using the trails.

With these tips in mind, your child will be able to enjoy riding their 20-inch mountain bike safely and responsibly.
