You want your kiddo to have a bike that is well made and has all of the same features that you would look for in an adult dirt jump bike. Luckily, there are some industry leaders that are going to be able to offer you a number of great choices.

Far too often companies that make children’s bikes sacrifice quality to be able to ensure that they are cheap. They are made with materials that are far too heavy for dirt jumping or tricks. The majority of kids bikes have poor quality components.

How to Teach Your Child to Dirt Jump Like a Pro

There are so many off ramp sculpted landing ramps and dirt jumps that are amazing fun and quality today. If your child has seen them, chances are that he/shes mouth is watering to jump them. The biggest thing to remember is that your child has to start with the basics and take things slow.

Different Types of Dirt Jumps

The firsts thing that you need to know is all of the different skills that your child should know before attempting dirt jumps. Here is a short list of them.

The Manual

The Manual is sometimes confused with other tricks like the coaster wheelie or the wheelie. These are a great first trick to learn as it is simple. To perform this trick you simply need to combine a few different elements. The first of these is heavy pedaling. Then there is the rear brake feathering and weight shifting. By learning how to do the Manual, your child will soon be ready to move on to bigger and better tricks. The coaster wheelie is very similar, but that requires you to stop pedaling and balance. However, with the Manual, your child will learn to shift their weight back and forth effortlessly.

Most of the time the Manual is a stunt that is used in street riding and is something where riders can perform tricks on rails and ledges. The Manual teaches a technique that is crucial for being able to double jump. The manual forces a dip in between jumps and uses additional pumping to increase the speed. The best thing about the Manual is that it teaches riders how to increase control and speed at the same time making it crucial for those who are wanting to start dirt jumping.

When approaching the first mount, your child will want to have their preferred foot in the forward position. They will need to keep their elbows and knees in a bent position while staying relaxed. Staying relaxed is key because if you stiffen, you are not going to be able to move the bike underneath you.

By staying loose, your child is going to be able to relax through the takeoff which will, in turn, help them to learn how to nail jumps later on. This is a trick that will help you to be able to keep moving forward when you are focusing on the jump. Additionally, by keeping your weight towards the back, you will be able to lift that front wheel up and perform tricks.

If your child wants more of a challenge, they can actually straighten their legs to extend their feet out in front of themselves. When they do this, they can even stand upright to show off some skill. Another thing that they should be doing to master skills is to extend their arms. Then they just need to pump the backside.

Boosting a Jump

The next skill that your child should learn is how to boost a jump. Boosting a jump is one of the most essential skills to learn before setting off on trails that feature jumps. The best rides will happen when they flow effortlessly with the jump and the moves that are required to land the jump. Your child will learn about depth and speed and how to combine depth and speed for success. They will also learn how much they have to pull up to be able to effectively make the jump. 

Being able to boost a jump is a skill that is great for learning how to make a secure landing and for trail riding hazards to be avoided.  To boost a jump, first, your child will need to learn to stand tall. They need to work with being able to throw their body weight in a forward motion as quickly as possible. They will want to extend their arms and legs to be able to take off successfully.

Next, they need to be able to push the transition, into using their arms and legs into the ground. Then your child can learn to explode off of the lip of the jump fully compressed. Then tuck the bike up and you will be able to ensure that the bike moves forward and makes a huge bunny jump.

The Squash

For times that you are moving and going to be gaining extra height to help you move into a bigger jump, you will find that you want to avoid jumping and landing in the transition. Then you will want to be able to move into different size of jumps. By mastering the squash, your child will be able to enjoy jumps at greater speeds and through different types of terrain. This type of jump is one of the most common types of jumps in racing.

The first thing that your child will do is learn to relax their limbs. This is a skill that is a bit more difficult because when your child is learning jumps they are often nervous and that makes it harder for them to attempt a jump. In addition, you will find that this skill of learning to relax when nervous will carry your child through a lot of sketchy situations, not just in riding.

When they have relaxed completely, they will be ready to absorb the lip. As the front wheel is lifted into the air, the bike will be moving up and away from the jump. Your child will need to keep the knees flexible so that they can raise their position in the air. Extend the arms and the bike will naturally arc through the air and stick the landing. This allows for your child to be able to gain height and even do their first trick.

Each of these skills is the basics that need to be practiced before you attempt any dirt jumping.

Buyer’s Guide for Dirt Jump Bikes

Purchasing a dirt jump bike for your child is a big decision and is something that you will hopefully find to be an enjoyable and healthy experience. You want to ensure that your child is going to be able to enjoy their time on the trails. Of course, it will be important for your child to learn how to be a safe rider to avoid any injury on these rides. You might not be sure about what type of bike you should be looking for, but you simply will want to take some time to consider what will best suit your child’s riding needs when purchasing them a dirt jump bike. 

Tips for What You Should Look For

A Good Frame

The bike frame is measured from the center of the head tube to the center of the seat tube. This measurement is known as the horizontal top tube length. It is an important measurement for anyone who is looking to buy a dirt jump bike. The tube length should coincide with height. If your child is tall, you will want a longer tube length and a shorter tube length if your child is short.

This is how you can be assured that you are finding the right size bike frame. There are typically sizing charts that manufacturers produce. They are typically fine for helping you to ensure that you are purchasing a bike that is the right size.

A Strong Fork

Another part of the dirt jump bike that is very important is the fork. You need a strong fork to be able to ensure that the bike is going to be able to withstand the abuse that it will take from the jumps. Most of the bikes that have a strong fork will be able to fully withstand any abuse that you can throw their way. The best way that you can test this is to approach the bike from the front and you can put the wheel between your legs. You then turn the handles from side to side and if you can see the fork twisting, it is not a strong enough fork. If you cannot be rough with a bike, you are not going to be able to ride it to withstand the abuse that it will take from dirt jumps.

What You Should Know About the Wheels

The wheels are another important part of the bike that you have to consider if you want the bike to be able to handle the jumps that it will endure when your child is riding and doing tricks. The wheels need to be sturdy. This is so that you can still allow your child to train on the bike. Bikes that are used for training on dirt jumps are often exposed to far more pressure and abuse than the wheels that are used otherwise. Bikes are put through additional strain when they are used for learning to dirt jump. This means that it is extra important when shopping for a kid that you choose a bike with sturdy wheels to withstand all of the pressure. In addition to this, you will want to make sure that you look at how many spokes are on the wheels. You want enough spokes for the wheels to be extra sturdy. A good number to aim for is 36. With 36 spokes the wheels are going to be far more sturdy than you will ever need. Plus, you should make sure that the tires are filled to 45 psi.

What to Look for with Chain Retention

Another thing that you should consider is the chain retention. This is more important with the single speed bikes because you want to ensure that the chains are tense enough to function properly during drop-offs and hard landings.

Make sure that you know some information about the frame and the material that it is manufactured from. Frames can be made from aluminum (also known as alloy), carbon fiber, or steel. A bike that has an aluminum or alloy frame is one that is going to be the most affordable option. If you have to stick to a budget this is a good choice. Additionally, the steel frame is a more solid choice and is much stiffer than the alternative. There is also a new mixture of aluminum and steel that is called Chromoly steel. This is a great choice as well as it is material that is going to be stronger than traditional alloy and lighter than traditional steel.

It is never going to be an easy task choosing a dirt jump bike for your child, but you will be able to tackle this with the right information. By having the right information, you will be able to easily skim through all of the options as well as how each of the safety features works. Additionally, by watching them on the track, you can watch how your child rides and figure out the best choices for a bike that is going to work with them and their skill level.

Safety Tips for Dirt Jumps

When your child is learning to ride a mountain bike and is going to be doing jumps. It is important for them to be able to learn how to do so safely. This can all be done with ease and the following tips are going to help you to have the highest safety standards.

Wear a Helmet

The first safety tip is one that should really be a given, but we are going to state it anyway. You want to make sure that your child is wearing a helmet that is in compliance with DOT standards.

Wear Protective Clothing and Gear

However, you are going to need more than a helmet to keep your child’s body protected. Some of this additional equipment includes safety goggles that are in DOT compliance standards. Having long sleeves, long pants, gloves and over the ankle boots are also important. These are available with DOT compliance standards as well.

Riding on Pavement

Most mountain bikes are not made for pavement. If you are learning to dirt jump, do not jump on the pavement. You always need to make sure that you are jumping safely and that you are permitted by law to do so. Another vehicle could hit your child if they are riding in areas where they are not supposed to be. This is why you should stay off of the highway and busy streets.

Supervision is Important

It is important to make sure that your child is going to be supervised if they are under the age of 16. This is because you do not want your child to be injured and not have someone there to help them. Dirt jump bikes are a nice piece of equipment and although they can be a lot of fun, they are not a toy. This is very important to note as so many parents do not feel the need to supervise their children.

Make Sure The Bike Fits Your Child’s Height

You want to make sure that your child has a bike that is the right height for them. If your child is trying to ride a dirt jump bike that is too tall, they are likely to have an injury or have problems. So, you will want to follow size guidelines when you are purchasing a bike for your child. This is one of the most important factors and something that will certainly assure that your child is able to ride safely.

Know the Power Your Child Can Handle

You need to assess your child and know the amount of power that they can handle. By doing this you will rest assured that your child is able to ride well without problems. They are going to be less likely to be injured or have problems. It is important to know and understand how much power a bike has and to make sure that your child is riding a bike that they can control completely.

Don’t Allow Your Child to Ride Alone

The most dangerous thing that your child can do when they are riding is on the trails alone. Being alone on the trails is not safe for a number of reasons. If your child is injured, you might not be able to find them.

Stay on a Safe Trail

Make sure that you are teaching your child to stay on safe trails. You want to ensure that your child is not used to riding in crazy places and that you are teaching him to ride in a way that is safe and going to be safe when he or she is an adult and venturing out on their own.

Ride at a Safe Speed

Trying to go through trails too fast is the number one reason that people end up with injuries. Make sure that your child is traveling at speeds that they can handle. If they ride too fast, they are more likely to end up with a serious injury.
