This solely depends on what you think is better for your child. To make things easier, let’s have a look at some things you should look at while picking the right mountain bike for your child.

  1. Make sure the bike is the right size for your child.
  2. Determine the weight. It’s crucial because if it’s too heavy, it won’t be enjoyable to ride.
  3. Determine your budget to get what you would pay for. This is important so you don’t end up purchasing anything you don’t like.
  4. Determine whether or not your child requires suspension for the type of riding he or she intends to do.
  5. Examine the gearing to ensure that it is not too difficult but has a sufficient range of gears for climbing hills.
  6. Check the major components of the bike such as tires, frames, brakes, saddles, and several others to know whether they are all working appropriately.

Mountain Bike Weight

If you are new to mountain biking, you may not realize that there are many distinct types to choose from. Downhill mountain biking, cross country mountain biking, freestyle mountain biking, and enduro mountain biking (also known as all-mountain biking) are the most popular names for these activities.

Mountain bikes usually weigh 20 to 45 pounds. But each of the four major mountain biking disciplines affects the mountain bike’s design, as well as how much it weighs. Since certain mountain bike features are interchangeable, you can modify any type of bike to make it heavier or lighter. Some of these modifications are simple to build, but others are much more difficult and costly to do on a mountain bike.

So, in addition to several other factors, you must choose the appropriate mountain bike for your riding style. Making a poor decision in this area could result in your mountain bike breaking down or slowing you down on the road. There are a variety of reasons why the weight of a mountain bike is important. Although the material of the frame is important, the size of the frame has an impact on the weight of the mountain bike. The bigger the frame, the larger the wheels that can be fitted to it. Taller mountain bikers can use bigger frames so that they don’t end up looming over their mountain bike when standing and aren’t scrunched up when getting on and pedaling.

Smaller mountain bikers, on the other hand, can choose a smaller frame size so that they can bring their feet down to hit the ground while standing over their bike. The size of the frame, as well as the material it is made of, are the two deciding factors that will account for the majority of a mountain bike’s weight. The wheel size you should choose is a separate subject, but it is a critical component of mountain bike selection. Simply put, larger wheels can take a little longer to react to sharp turns as well as some of the trail’s technical features.

The weight of a mountain bike can influence your speed to some extent. One of the key reasons why people want to reduce their bike’s weight is that when trying to go uphill, the more you pedal, the more weight you have to carry up the hill. The weight of your mountain bike, on the other hand, is usually just a fraction of what you weigh. As a result, true mountain bikers can reduce their weight as much as possible rather than wasting money on a new bike component that weighs less. In reality, if you’re a big guy, going with lighter parts for your mountain bike may be a bad idea.

The explanation for this is that, in most cases, lighter components are not designed to withstand higher pressures. When you weigh a lot, or even slightly more than you should, you put more weight on the bike, which puts more pressure on it. As a result, if you are heavy, your bike should also be heavy, or you risk losing a component of your bike. Overall, even though you are just going mountain biking, you should consider your weight when selecting a mountain bike.

Frequently Asked Questions

Is it Possible for An 11-Year-Old to Ride a 20-inch bike?

The 24-inch sizes are the most typical bikes for kids aged between 8 to 11 years. If your child is short, a 20-inch bike will be ideal for him/her. To find the right fit, you must first calculate your child’s inseam and height. When doing so, make sure to calculate the bike’s height with the seat completely down

How Do I Know What Size of a Bike to Buy for My Child?

The wheel diameter of a kid’s bike is measured in inches which is between 12, 16, 20, and 24. You should be able to figure out what size of bike will be ideal for your child based on their age. Generally, a 2 to 3-year-old child will ride a 12″ bike, a 4 to 5-year-old child will ride a 16″ bike, a 6 to 8-year-old child will ride a 20″ bike, and an 8 to 12-year-old child will ride a 24″ bike unless they are taller than expected.

What Would I Do to Get My Child Interested in Mountain Biking?

Allow him/her to practice standing without a bike first, then progress to concrete paths and eventually dirt trails. When teaching your kids mountain biking, start with a dirt road or a parking lot so you can ride alongside them to see how well they can navigate and stop the bike.


The performance of your child’s bike is one of the most important factors in knowing how much fun they can have in mountain biking. It doesn’t have to be the most costly or adorable mountain bike for it to be enjoyable, but it must have a lightweight design, fit properly, and function well.

In terms of how well a bike can work for your child, weight, in particular, is a huge differentiator. It is a fact that your kids weigh significantly less than you, implying that the bike-to-body-weight ratio must align appropriately. If your child is riding a mountain bike that is too heavy for them, they may get exhausted quickly, irritated easily, and may abandon the sport altogether.

The appropriate geometry for the child, easy-to-operate brake levers and shifters, and other good components are all features to look for in kids’ mountain bikes. After all, you wouldn’t like to spend a lot of money on a bike that will depreciate in a year or two. Also, you wouldn’t want a bike that is constantly breaking and dropping its chain. So, there is the need to make the right choice when getting mountain bikes for your kids.
