You are here in search of a good mountain bike for your kids? Well, you are almost there to accomplish the first step of your kid’s mountain bike journey. And I am here to assist you in finding the best mountain bike for your kids.

Finding the right mountain bikes can be a daunting task, especially when your kids are 7-10 years old. Because they are not little toddlers who need training wheels and neither are teens who don’t need any support at all. But with a little research, the process of finding the best quality mountain bike can be fairly straightforward.

In this guide, I will familiarize you with the top brand kids’ bikes, and all of my picks are different than each other in size and the best in their community. All are available in this guide. And I will acknowledge you about these best mountain bike features and benefits, along with my opinions on customer reaction.

Things To Consider When Choosing The Best Mountain Bike For Your kids

I don’t want you to feel you have made the wrong decision and be disappointed later. That’s why I am writing this guide on some factors that you must consider to make a fair decision. If you keep these in your mind while choosing your kid’s mtb bike, I am damn sure you will not regret it. Let’s know what these are.

Lightweight: If you ask me to tell you one factor that can ensure your kids have a good mountain bike, I will tell you to pick a lightweight mtb bike. A lightweight mountain bike is likely to be more appropriate for younger children who are not yet ready for a heavy mountain bike. Additionally, a lightweight mountain bike may be more suitable for a child who is just starting out and wants to experience all the different types of terrain that a mountain bike can offer.

Suspension: Full suspension is generally the most suitable option for kids due to its greater cushioning and stability. Especially for heavier kids or kids who want to have a more aggressive riding style. It provides a more stable ride that is great for downhill and freeride riding. Front suspension is a good choice for smaller and lighter kids who want a playful ride and don’t want to worry about bumps and bruises. Rigid suspension is perfect for kids who are Jr. or Sr. riders. 

Gear system: For beginners, a single speed is a good option as it is easy to learn on and does not require a lot of gears. As children progress, they may want to switch to a 6 or 7-speed gear set. 6-speed gear is ideal for intermediate riders who are looking for gear that can help them cover a variety of terrain. It is a good option for those who want to ride fast but also have control over their bike. While a 7-speed gear is perfect for more experienced riders, who are looking for an intermediate gear that can help them cover a lot of ground quickly. And a 21-speed gear is best for kids above 10 years; it offers more options for faster speeds and is more durable.

This suspension system helps to absorb bumps and shocks, improve balance and coordination; making it great for kids who are new to the sport, and preventing them from getting too excited and crashing into things.

Shimano 6 Speed Indexed Derailleur:
With a 6 speed indexed derailleur, kids will experience increased speed and control when riding their mountain bikes. This is due to the fact that the derailleur moves quickly and smoothly across the cassette than a traditional derailleur, providing a more responsive and dynamic ride.

Key Features of JOYSTAR Contender Mountain Bike

Frame materials: Hi-ten steel frame bike is adjustable, so it can be tailored to your kid’s height and weight and will be easier for kids to ride in a comfortable position. Additionally, a high-ten steel frame is not as stiff as other frames, making it easier to control and ride. And it also resists deformation, making it the perfect choice for kids who love to ride their bikes hard.

Suspension: This joystar kids bike features dual suspension, the front suspension fork, and the rear spring shock that offers comfortable riding, handling, and stability. The suspension fork helps to absorb bumps and jarring impacts and provides a smooth, responsive ride; making the experience more enjoyable for the little rider. The rear shock also helps to dampen the bumps so that the bike stays stable even when going over rough terrain.

Braking system: Having a front and rear linear-pull handbrake on a kid’s mountain bike offers safer riding, decreased risk of being involved in a crash, and improved control. This braking system is always applied evenly and firmly, eliminating the risk of sudden stops or skidding. In addition, they provide increased control when cornering or hard braking and the handbrake can be easily activated with one hand. This makes it easier for kids to stop quickly and avoid accidents.

Gear system: This contender bike features a 127mm 1-piece crank and a 32T steel chainring along with an American loose ball-bearing bottom bracket. This unique design provides increased durability and performance, making it the perfect choice for those who demand the very best in cycling equipment. The 1-piece crank is also more compact and lightweight, which makes it easier to pedal. The 32T chainring provides a wide range of gear options, while the loose ball-bearing bottom bracket ensures smooth gear shifting and long-lasting durability.  

Handlebar: Featuring the Hi-Ten steel handlebar and fork, this bike is definitely worth considering. Developed in collaboration with professional riders, the Hi-Ten steel handlebar, and fork are designed to provide the rider with the responsiveness and accuracy they need to dominate the off trails The handlebar and fork both are made from high-quality steel and joined by a 60mm stem for maximum steering performance.  The Hi-Ten fork is also adjustable, so you can fine-tune its ride quality to your liking.
