Why should teens and adults have all the fun? An electric dirt bike for kids can be a great way to introduce children to motocross and encourage a love for the trail at an early age.

Getting them out of the house and onto the tracks, electric e-bikes are ideal for helping youngsters to learn balance and throttle whilst also promoting rider readiness and building confidence. 

However, choosing the best children’s electric dirt bike can be a challenge since there are multiple points to consider.  

To make your life easier, I will examine this further, breaking down the basics and concepts that you need to consider when choosing the right one for your child.

What is an electric dirt bike?

Promising power, speed and improved safety and control, electric dirt bikes have been designed for off-road tracks and closed trails. 

In many ways, they are similar to a traditional dirt bike, however they feature a battery and electric motor that generates power.  

Be aware that laws and regulations related to electric bikes on the road do vary by state and country. As a result, it is important to check out the rules in your local area before investing.

How do I choose the best electric dirt bike for my child?

When selecting the ideal battery-powered transport for your mini dirt bike rider, the most important points to consider include:


As with most things, the more money you spend, the better quality your purchase. 

However, the best models can be expensive and seeing your child breaking your expensive pit bike, may be a deal breaker. It can also be quite a significant outlay if they change their mind. 

If your child is just starting out, consider a second-hand or a refurbished motorbike, and make sure to check dirt bike reviews for the best affordable models.

Child’s Age

The best electric dirt bike for kids is one that is age-appropriate. 

It is suggested that once a child is capable of riding a bicycle without training wheels, they are old enough to ride an electric dirt bike. 

Most kid’s dirt bikes are age-specific, and you should also take your child’s size, skill level and experience into consideration. 

For example, you may wish to opt for a lower power dirt bike (350watts) until they have grown in confidence. By contrast, you could a buy 650watt electric dirt bike for a 12 year old rider.

Minimum Safety Measures 

Motocross can be a dangerous sport, and there must be appropriate safety measures in place to avoid an accident. 

Dirt bike riders should always wear a helmet, pads and goggles to protect their eyes from dirt and mud. 

As well as the usual bike safety measures, children also need to be aware of the importance of driving safely. 

Electric dirt bikes can be safer than traditional dirt bikes as they do not have the hot motor and exhaust and do not need petrol.

Give them a safety lesson before they ride to ensure that they know how to handle it and how to sort out unexpected moments.

Motor Power in a Electric Dirt Bike for Kids

motor bikes, kid dirt bikes

The motor power of any electric motorbike dictates the speed and torque (important for this category). 

Typically, electric dirt bikes are usually between 350 to 650 watts, similarly to an e-MTB.

Although speed is very much part of the fun, it can be dangerous. For younger children or newbie dirt riders, a less powerful bike is recommended.

Suspension and Brakes

If you are riding over rough terrain, decent suspension is necessary to ensure safer handling and a smooth ride. 

You should also make sure that the dirt e-bike is equipped with specially designed brakes for motocross sports.

Weight and Size

One of the most important points to consider is the height and weight of the child in relation to the bike you choose. 

Small Kid’s electric dirt bikes often have a weight limit of around 20kgs; therefore it is important to check your child’s weight in line with the manufacturer’s recommendations. 

To check that your purchase is the right one, your child’s hands should easily be able to reach the handle and make sure that their feet can touch the ground.

Electric vs. Traditional Electric Dirt Bikes


  • Safety:  Electric dirt bikes are considered to be much safer when compared to those with petrol engines, with the engines on the latter running much hotter.
  • Suitable for Beginners: Improved ease of use and control means that electric dirt bikes are a great option for kids and beginners.
  • Friendlier Choice: Electric dirt bikes are much quieter than gas bikes, so they are much less likely to annoy the neighbours. Plus, they are much cleaner and better for the environment.
  • Easier for non-mechanical parents to maintain  


  • Limited Battery: Ride time on an electric dirt bike is limited, and as a result, long ride days may not be possible.
  • Decreased Power Delivery: Electric dirt bikes tend not to be quite as powerful as traditional ones.
  • Maintenance has to be more frequent than high-end electric bikes with almost similar characteristics.

Difference between electric dirt bikes and high performance electric mountain bikes 

electric kids motorbikes, motorbikes for kids

At this point, you have learnt most of the basic concepts regarding e-dirt bikes. 

I know I get very excited on how powerful and fun dirt bikes can be, however I have also found that a lot of e-MTB can deliver top quality for kids.

Over my research for trusted electric mountain bike reviews, I landed on a few good alternatives at Electric Bike Advisor.

According to their analysis, most full suspension electric mountain bikes, such as the Giant Trance E+ 3 Pro, are a viable alternative to a kids electric dirt bike. 

Regardless of their opinion, I think that the obvious difference is the size and most likely the final price.

In addition to the above, not all kids would be able to enjoy an e-mountain bike due to their size and weight (roughly 30 kgs).

Wrap Up

Advancements in technology and electric motorsports have meant that the world of electronic bikes is constantly changing.  

Remember to always make sure that children are kitted out in the relevant safety gear, including a quality helmet, goggles and elbow and kneepads.

I know there is more information relevant to this topic, however, this buying guide has examined the basics you should know when selecting the best electric dirt bike for kids.

With a progressive valve system, the front end runs an inverted 37mm Showa open cartridge fork that tunes damping to equalize the strong rear shock. In addition, the RM 85L has 48.3cm front and 40.6cm rear tyres. The wheelbase is 1.280 mm and the seat height is 875mm. The bike comes with graphics to make it look good for competition and a bonus race kit.

Can you Rely on Suzuki RM85L?

Suzuki has chosen to stick with the RM85 lengthy engine production run because it is reliable. It has been tried and tested over time. The RM has been a popular race machine for many young racers for years. People riding the bike have not complained about common mechanical problems. If serviced regularly and kept in good condition, the bike is very reliable. However, if it overheats or if you leave the piston in there for too long without replacement, there can be an engine failure just like other motorcycles.

When should the RM85L be used?

Source: Suzuki

The RM was once a front runner but not anymore. Due to a lack of development, the RM is not up to scratch compared with the industry’s new models. It does not have the same high-quality suspension standards.

It does, however, have its place. While it may not be the best for Australian championships, it may be suitable for an A-grade junior joining the championship. The cheaper price tag is worthwhile for anyone who is on a budget but wants to race competitively. The less aggressive power means it is a good choice for beginners, as it is easier to operate. The RM85L is perfect for kids who enjoy riding with the family, on farms, or just recreationally. While it is not advisable to neglect it, the bike is capable of withstanding a bit more neglect more than most brands do. 

  • Affordable compared to other models
  • Comes with a bonus race kit valued at $1,100 (AUD)
  • Unequalled braking performance that gives excellent feel at the lever
  • Confident and smooth handling on tough terrain
  • It can bog when the revs drop too low
  • Low-quality suspension compared to class leaders
