Taking up any biking activity at a young age is a good idea. Children who learn to ride a cycle early, tend to have good control over their body balance. They also improve their reflexes as they learn to be quick on their feet while riding a bike. Combine it with an accelerated development of motor functions. By the end you will be well-informed to make a decision regarding which is the best ride-on toy for your kid.

Moreover, if you’re going to teach your kid to ride a bike, it might as well be a mountain bike. They are great for fitness activities and help kids to explore their surroundings properly. However, mountain bikes have evolved a lot from their original model. We will help you to find the best kids mountain bikes.

At the same time it’s crucial when buying a bike for your kid that you get one that best suits them . Besides, there are also a couple of other factors that play a part in deciding what kind of mountain bike a kid should have.

Factors to Consider While Purchasing The Best Kids Mountain Bikes 2020

1. The Right Size

Even if everything else is wrong with the mountain bike, you have to make sure that at the very least, the bike is of the right size. While everything else can be worked around, the size isn’t something that a rider can compromise with.

Plus, it’s always better to let your kid master a bike and then let them progress on to the next stage, instead of immediately handing them something that is bigger than them. As for the used bikes, you can always sell them or give them to another kid, maybe even your kids’ younger sibling.

It’s never fun for a kid to ride a bike when their feet can’t touch the ground while they are sitting, and the brakes too can’t be reached properly because your child’s body doesn’t let them reach that far. It becomes the perfect recipe for an accident. If your kid crashes too frequently while they are on the new bike, they will soon lose all determination that they had to master the art of riding a bike.

Broadly, the bikes can be divided into four categories according to size. For preschool kids, you can look into mountain bikes that are in the sub-16 inch wheel range. As for the kids who are at least 4 to 6 years old, they can handle a 16-inch wheel bike The ages of 6 to 10 are perfect for the 20-inch wheel size, depending on how much the kid has grown during this time. We can safely say a kid from 9 to 12 years old is capable of handling a 24-inch bike.

After that, it’s better to buy small adult mountain bikes for kids.

2. Weight

Weight has more of an impact on the fun and maneuvering of the bike on children than adults. Children are naturally lighter and weaker than adults. What is a 1 pound heavier for an adult can feel like 10 pounds for a kid. If you gift them a bike that they don’t cannot move or have to exert a huge force to move it every time, then they are going to get tired of it and give up learning to bike.

3. Cranks

Similar to adults, the cranks for children should be about 20 percent of the inside of the leg length. Another often followed rule is tenth of overall height rule of thumb. In some cases, the second one does offer inaccurate measurements. This is because some people have inside leg measurements that are overall half of their height. However, overall, it is something that can be trusted.

For manufacturers, they seem to believe the only rule of thumb is to stick to whatever they believe to be the next size of bike on should be. Over long cranks look bad as they are inefficient for the effective handling of a mountain bike. They also have a history of grounding easily if the manufacturer doesn’t put the bracket higher. And the children do not need the bracket to be higher.

So, make sure to be careful while checking for the crank size on the bike.

4. Wheels and Brakes

For small riders, you don’t need to buy big wheels. You only end up scaling them down. We can’t deny that a larger wheel will have a better possibility of absorbing shocks and rolling over bumps, especially if you do plan on letting your kid on rougher terrain. However, it will also be heavier, weighing down the whole bike and steering it will be hard, especially for beginner bike riders.

It’s very likely the kids will have a harder time reaching the bar too, for the distance between the bottom bracket and front axle will increase, and the bottom bracket will naturally be placed higher. All these factors contribute to making a bike that’s a bit too large for the kid making it harder to control than a perfectly fitted one.

For brake levers, scaling down isn’t necessary for the most part. That’s because the alternative option of two fingers adult levers exists. However, it is imperative that they are also within reach of the bars, and the kids don’t have a hard time operating. You can check for an adjustment crew in this case. Make sure your kid’s little fingers on both hands is enough to operate the brakes.

5. Reach

The one measurement that can’t be scaled down for children’s mountain bike is the reach. Most children feel best when they can ride the bike in an upright position. For this, the bars have to be a little higher than an average adult bike and closer. This is why BMX bars are perfect for bikes with 20-inch wheels or the ones that are smaller than them.

6. Suspension Forks

For children, we would recommend going for air-spring forks. These suspension forks are light, and adjustments can be made in accordance with to the growing weight of the rider, as time passes by.

For coil forks, you’re going to need lightweight springs. Sticky forks might be too hard for children to handle, for they lack the mass that is needed to get the forks moving. However, it is better to opt for rigid forks then end up with bad quality suspension forks.

The Age Guide to Buying the Best Kids Mountain Bikes 2020

We have looked through several factors that should play into our decision while we are looking for mountain bikes for kids. However, things will be better understood if we tackle the bike situation from an age perspective too. Which is what we have covered in the next section.

1. For Pre School Kids

If you are searching for bikes for pre school kids, it is most definitely the first bike they will lay their hands on. It is safe to assume they have no previous experience with bike riding, let alone mountain bikes.

The set of wheels at this age is usually either a trike or push along. These are plastic that is prone to breaking, and friction bearings on them are too simple. They are more for a preparation for a kid to get on a proper mountain bike than it is actually suitable to ride the mountain terrain with these wheels.

If you get a decent metal trike, they are likely to last for a long period of time, and you might even get to hand them down to younger kids. For kids of this age, you must look for bikes where the rear wheels are wide-set to provide stability, and a front-wheel axle that you can proudly say is durable. If they have proper ball bearing, all the better.

Most children are capable of learning how to ride a two-wheeler by the time they turn 3, and by 5, you can be certain your kid will be capable of mastering it. If they learn how to at least balance and steer by the time they are 5, bike riding becomes much more fun and an easy sport.

One can use two methods to learn to do so. One is the common two-wheeled scooter, or you can opt for a hobbyhorse. You can add stabilisers to bike, and they will help your child with mobility if they don’t know how to balance. However, stabilisers aren’t helpful for children if you actually want them to learn how to ride the bike.

You can use a starter bike and turn it into a hobbyhorse by removing the pedals and lowering the height of the seat at a level so children find it easy to put their feet on the floor. Look for a gentle slope and let them get on top of it. Now, have them coast down towards you at a gentle and slow pace. Once they get the hang of it, you can attach the pedals back again and coast towards you again, only with the bike properly fitted.

It is best for the first bikes to stick to 12 to 14-inch wheels. The standover height should be low, and it is best if it has ball bearings in the hubs, the bottom bracket, and headset. The cranks should be around 90 mm to 100 mm. The tires should be pneumatic, and at least one brake should work on the bike.

2. The Bikes For Age Four To Six

There are bikes out there with 16-inch wheel and still have training wheels. Do not go for those, and if you do, you can remove the training wheels. For all 16-inch wheel bikes, the gear is always single speed. This is because the chainstays aren’t long enough for derailleur gears, and at this age, different gear options only help to confuse the kids.

Of course, a three speed gear hub is always nice but they are too expensive, and so manufacturers don’t make them. The children don’t travel far at this age anyway, so they should be fine with single-speed ones.

The overall weight of the bike should be low to make maneuvering easier. Let’s do away with suspensions and steel frames that are flat. The thin steel tube frame should be good enough. The bottom bracket should be lower to allow your child to put their feet down from the saddle. As they have better control of riding now, you will have to be raising the saddle too.

Keep the cranks from 100 mm to 120 mm range with more preference towards the lower 100 range. Look for chain guards as they will help you keep the clothing or a finger from catching into the drive train.

Children know how to hurtle through the bike at this age, so a bike that can be easily operated is a must. A v-brake or a side pull is fine on the front, but it’s no good for rear brakes. As the cable line is long, it produces less friction, which makes it hard for children to pull. The best option would be to go for a back pedal coaster bike.

3. The Bikes For Age Six To Nine

For 20-inch wheel bikes, gears are the obvious extra addition. If you can get a three speed hub gear, there is nothing more ideal than that. Kids can get a good grip on it easily, and the gears don’t break easily. But, as we mentioned before since it is expensive, most people settle for five- and six-speed derailleurs.

If it’s just limited to a certain area, you can still fit in single-speed. They are lighter than any other gears, simple and rarely seem to have any problems associated with it.

There are some 20-inch wheel bikes that you will find have suspension forks on them. They are usually on the basic side, and the springs are adjustable. Nevertheless, they are liked by children. They do have some disadvantages associated with them. For starters, more weight is added, and the money you could have spent anywhere else on the bike is forced to be spent on the bike because of the manufacturer’s decision. The front suspension might be good on those, but the rear suspension rarely is.

If there is a rear derailleur on the bike, you will have to get a derailleur guard too for when the bike is lying on its side. It comes with a kickstand, even better. Kids these age rarely take into consideration that propping the bikes up is a viable option.

For the shifters, look for the ones that are easy to operate. The cranks are again elongated. You still want to stick to 120 mm to 130 mm range. At most, you can opt for 140 mm one.

4. The Bikes For Age Nine To Twelve

It’s time to spend a little more on bikes, providing that they are investments that can be passed on to younger siblings. A lightweight aluminum frame mountain bike should be the perfect option. Alternatively, we will love to see your kid with a wheel of 24-inch and a single chainring. If we could get a wide range eight-speed hub, even better. However, those are too expensive.

A seven-speed hub with screw-on freewheel isn’t bad either. Especially if it has a triple chainset on the front. If the chainset is double, try to look for one with a smaller inner ring and not one with a large outer.

At the same price, the specs for this should be comparable to that of an adult bike. An alloy seat-post that your child can adjust to fit his or her height, a bottom bracket made of cartridge, a riser bar, a good set of wheels and branded v brakes should be there from the start. For mountain bikes, off road tyres should excite your kids.

Don’t go looking for disc brakes. Instead, check for disc mounts so you can upgrade it later. The suspension fork should be adjustable and damping, but don’t choose full suspension. The cranks get longer with these bikes and push up to 140 mm or 150 mm. You might even get a 160 mm one.

5. The Bike For The Big Kids

If your kid is over 12 or even some cases if they are young but on the tall side, they are most certainly ready for small framed bikes that are actually for adults. The frame size is shortened down to 14 inch or 15 inch. Some even have it at 13 inch. If your kid is a bit of an expert at mountain biking by this age due to the time they have spent doing it as a kid, they might prefer the one with the smallest frame so they can get a satisfactory level of clearance with the top tube.

Most teenagers would be satisfied at 15 inch though.

This in no way means you should put your 10 year old on an adult mountain bike because they are capable of reaching the pedal. They will work much better on a bike with 24 inch wheel and with a frame within the 12 inch or 13 inch range. The bikes with 24 inch wheels are simply lighter and far more easier to control.

Imagine it for yourself. Would you want to deal with a bike that has 28 inch wheel instead of a 26 inch one? Don’t forget to look for the ones with cranks that are suitable for kids.

At teenage, children have to deal with peer pressure and will automatically have preference towards bikes that makes them look cool. The current trend seems to be a good work with the paint job and a dirt style frame.

Some More Things To Know

Things to note before you start to ride those bikes first. Before you get your kid on the mountain road, here are some tips you should apply.

1. The Preparation

Don’t put your kid on a rocky terrain from the start. Let them get use to the plain, smooth pavement around your house first. Once your child is comfortable handing the bike on a flat plain, you can take them to places with dirt trails with interesting topography.

We have said this again and again, but the bike size needs to be exactly right if you are going on the rough trails. The wrong size will not only lead them to have a harder time while learning the mountain bikes, they are also more prone to accidents.

Choose a short path that you think your kid will have exploring. Better yet, if you choose a path you are familiar with.

Don’t make the bike path too long. Start with short paths that doesn’t take too long to get a round of.

Again, the trail should fit the difficulty level your child is capable of handling. Don’t force them into something they can’t handle.

2. Look For A Bike Park

If you aren’t confident enough to leave them on a rough, rocky terrain, it’s better to start with bike parks. In a bike park, your kid can learn to explore different challenges and yet operate under the assurance that you are there as well the bike park is proofed enough to protect them from injuries.

A child can also go over a single obstacle over and over again until they are confident they can conquer it no matter how many times they try to tackle it. A couple of hours a week spent on the bike park should be enough to get your kid confident in their riding skills. Let your child set the practice goals by themselves and offer them support and encouragement when they need it.

3. The Risks

You will be surprised at how fearless kids generally are. The amount of challenges and obstacles they will go over in such a short amount of time will genuinely amaze you. The level of difficulty they phase also need to be amped up to build up on their confidence.

Offer them trails that has challenges that are a little beyond their level. Be their to coach them through the trail and if possible, offer them a demo on how to do it yourself. If they are hesitant about something, do not force it on them. Instead, you can try to break the options into simpler steps to make it more understandable and even perform it together with them.

The most important advice that we have to offer is this; make it fun. Don’t act like a coach or a trainer. Remember, you started teaching your kid mountain biking because its fun. If you take the fun element and turn it into competition, they will only be put off by it.

4. The Injuries

We all want our children to not get hurt to the best of our abilities. The primary reasons why we are looking for the best mountain bike for kids is this.

Bruises are inevitable though. If the trail you have chosen is for mountain biking and if you have a mountain bike, your kid is bound to come up with some bruises once in a while.

It’s not easy to see but we must understand that it’s fine for kids to get hurt a little. Injuries are a part of the growing up process and kids are way more resilient than us. Falling down will only make them determined to get back up faster.

Of course, that does not mean you grown completely slack. You should be ready with a first aid kit in case the injury is higher than you anticipated. You should also make them wear safety clothing to absorb as much of the shock as possible. Never let a child get on a mountain bike without a helmet.
