Dirt biking is becoming one of America’s favorite past times, and there are several strong reasons for this - it lets you spend more time outdoors, you can do it with your kids, and it’s exciting!

However, it’s not all fun and games when it comes to these motor vehicles because they turn out to be a severe polluter.

The U.S. Environmental Protection Agency claims that a two-stroke engine dirt bike can emit the same amount of pollution per hour as thirty cars. This does a lot of harm to mother nature, and if you and your family do not want to be a part of this, then you better look up electric dirt bikes.

Luckily for you, we’re going to help you do just that. Our article contains a list of reviews that ultimately let you know which is the most quality Razor electric dirt bike for kids. So what is an electric dirt bike?

An electric dirt bike is an off-road motorcycle that is powered by a battery, contrary to the traditional one that uses gasoline. It isn’t as powerful but is eco-friendly and it is a great option for kids who want to ride.

Razor is one of the leading manufacturers of electric vehicles for children and today, we will be reviewing their top 5 dirt bikes to assist you in choosing one for your child.

In this section, we are going to explain which aspects of the electric dirt bikes we inspected. We find each of these to be an essential contributing factor in the buyer’s decision-making process and we hope that we covered the thing that interests you the most.


Age: what is the recommended age of the user for each particular bike model. You will notice how the manufacturer always raises the prescribed number of years, so if they say that a bike is intended for 13-year-olds, in reality, it can be ridden by 10-year-olds as well.
Weight of Rider: the weight capacity of the dirt bike. This is the maximum weight of the rider that the bike can support, and it shouldn’t be neglected.

Technical Specifications

Weight and size: how heavy and how big is the bike. The weight of the bike is presented in pounds while the size is in inches.
Material: what materials is it made of. Different parts of the bike are made from different materials, and we will generally write about the main part, which is usually made of steel.
Performance: what speed can the bike reach. Speed is an important feature as some people prefer faster models, while others will want something more moderate since these products are intended for kids.
Battery: how long can the battery last. Knowing the battery life (and how much it takes to charge) is crucial when planning your child’s rides.


Brakes: how responsive the brakes are. The more you know about this, the easier it will be to pick the suitable bike for your child’s age and skill level.
Controls: whether the bike has single speed or variable speed settings.

Value for Money

Price: the total cost considering all the factors. You will see that it is not uncommon for a maker to overprice their product, so read this section carefully.
Warranty: length and type of warranty. Some bikes have been reported to be delivered with malfunctioning parts, so it is crucial to have good warranty.
User reviews: what users have to say about the bike. What better way to get unbiased information about a product that from fellow users.

Electric Dirt Bikes – Our Full “MX Series” Review

1. Razor MX650 - The best electric dirt bike

Razor Dirt Best Electric Bike SX650

Rating: 92/100

What we liked
• Quality build
• Very safe and comfortable to ride
• 90-day warranty

What we didn’t like
• It takes 12 hours to charge the battery

‘We've had this for nearly three years, and it has been through the woods, mud, rocks, gravel, water - left out in the rain, sat through snowstorms and is still running quite well! We haven't had to replace anything - even the charger has held up wonderfully!’ – this is what one user had to write regarding the bike's durability.

MX 650 is the fastest out of all five bikes that we’ve reviewed today. Besides this, it is probably the best bike that this company has to offer.

Ok, so this one, being a serious machine, requires the rider to be at least 16 years of age. The weight limit is 220 lbs which means that most teenagers will be able to ride it with the exception of physically “advanced” ones. However, we personally do not see any problems with allowing younger children (10 years old and up) to have a go at this bike, as long as they know how to handle it properly.

The bike’s dimensions are 56 x 24.5 x 36 inches, and it weighs around 90 pounds. The sturdy, steel construction guarantees quality and its authentic frame geometry help to generate additional power when going uphill. Its maximum speed is 22 mph which makes it the fastest Razor electric dirt bike. It might not sound like much, but this is a lot when it comes to these vehicles.

The 12V triumvirate (36V total) rechargeable batteries can last up to 40 minutes after which they need to be charged for around 12 hours. In case you were wondering, the number 650 stands for the wattage of the motor.

Safety is the most important characteristic of a bike, and this one passes the test. Its throttle is very easy to use as it has variable speed settings, and the front and rear handbrakes stop the bike immediately. The latter is due to a dual disc braking system which is very responsive. The tires are large and knobby, and they make the ride pretty comfortable.

The manufacturer offers a 90-day warranty for this model, which is standard for all their bikes. Now, as far as the price is concerned, MX650 goes for around $430 on Amazon, which places it among Razors more expensive models. However, do not let the price throw you off as it is well worth it.

All of the above would be the reasons why we decided to award MX650 with the 1st place, as no other models display such an amazing combination of features.

2. SX500 McGarth – The Runner-Up

Razor Dirt Rocket SX500 Motocross

Rating: 88/100

What we liked
• Sturdy and reliable
• Beautifully designed
• Comfortable and easy to ride

What we didn’t like
• Expensive
• The battery takes 12 hours to charge

If you love motocross racing, then you surely know who Jeremy McGrath is. Razor decided to call their SX500 after this legendary rider, and we can say that this bike is worthy of its name.

The age requirement for this model is 14 years. Again, user reviews claim that younger children can ride it without any problems, and we share this opinion. The weight capacity is 175 pounds, which is excellent for a bike of its size.

Speaking of size, SX500’s dimensions are 56 x 36 x 24.5 inches, and its weight is 98.2 pounds, which makes it pretty similar to the MX650. However, it is not as fast as the former as its maximum speed is 15 mph. The same as all bikes from this manufacturer, it is made from steel.

The variable speed motor gets its power from three 12V batteries, totaling at 36 V. Fully charged it can last around 40 minutes, and then it needs another 10-12 hours to recharge.

How safe is it? Well, we would say that its safety level is on a standard, high-level just like all other Razor Bikes. It’s easy to maneuver, with the twist throttle and dual-disc handbrakes, and the handlebars are adjustable.

If you thought that you could buy this Razor electric dirt bike cheap, think again. Its current price is $460, which is a lot, and it has the usual 90-day limited warranty.

No doubt that this is one of the best bikes on the market right now, so you’re probably wondering why it ended up second on this list? The reasons are minor, but are not to be neglected - it lacks power compared to MX650 and is a bit more expensive.

3. Razor MX350 – Great Budget Dirt Bike for Kids

What we liked
• 90-day warranty
• Comfortable to ride
• Relatively cheap

What we didn’t like
• No shocks
• No parent-lock for speed limit adjustment

Razor Electric MX350 Motocross

Rating: 83/100

The MX350 is a perfect vehicle to help a child transition from a bicycle to a motor-powered two-wheeler, and in this section, we are going to look at the most critical aspects of this product.

First, of course, comes the recommended age of the riders which is 13 and above, according to Razor.

As with the previous models we reviewed, we believe that this is an overestimation and that younger kids can ride it easily. This is especially true considering the fact that MX350 supports weights up to 140 pounds, which some teenagers have already surpassed.

How big is the bike? Its size is 44 x 24.5 x 31 inches which is significantly smaller than MX500 and MX650.

Naturally, it is also lighter weighing around 63 pounds. As you could have probably guessed, this model is less powerful than the previous two.

The motor has 350 watts, and the battery is only 24V. Because of this, the bike can only run for around 30 minutes until it uses up all the juice. It can reach the maximum speed of 14 mph, but this largely depends on the weight of the rider.

Now, when it comes to controls, this bike has a twist throttle which makes it pretty easy to maneuver. It has a single speed setting only, and considering that it is intended for beginners, this is ok. Its lightweight also adds to the ease of use, and the brakes are excellent as well.

A big downside is that MX350 does not have shocks to absorb the impact when riding on rough terrains. Luckily, the knobby tires are there to prevent the rider from bouncing too much. Another con is that there is no parent-lock so that you can limit the max speed if you don’t want your kid to be riding too fast.

This model more affordable than the previous ones and it goes for around $250, which is a great price. If something goes wrong, you have the usual 90-day warranty. After this period, it is necessary to conduct regular maintenance because Razor electric dirt bike parts aren’t very cheap.

The MX350 was included in this list because we believe it is a perfect product for young kids wanting to try out a motorized ride. Since it has some drawbacks compared to MX650 and SX500, it earned third place.

4. Razor MX500 – Good, But Too Expensive

What we liked
• Safe and comfortable to ride
• Sturdy and quality build
• 90-day warranty
• The motor is not noisy

What we didn’t like
• Doesn’t have variable speed settings
• The battery takes 12 hours to charge
• Expensive

Razor Electric MX350 Motocross

Rating: 75/100

The MX500 is another fantastic bike from Razor. It is a bit lighter and less potent than MX650 but not of lesser quality in any sense of the word. Let’s take a closer look at it.

The company advertises this model as suitable for teenagers, but some of the users do not agree. A 14-year-old child would probably be better off riding the MX650 than MX500 as the latter could easily be too small for them. On the other hand, an 8-year-old could surely have loads of fun with the MX500 without any problems.

The weight limit is 175 pounds so make sure to keep that in mind before you give it to an older and heavier kid. In case you have a child that’s 11 years old or younger, this model should be good for them.

The bike is 46.5 x 13.7 x 26 inches large and it weighs 112 pounds and is made from steel. As for the motor, this bike packs a 500-watt high torque electric motor. It is powered by a 36V battery which can last for around 40 minutes (around the same time as the MX650’s battery) and needs to be charged for 12 hours.

The maximum speed that this bike can reach is around 15 mph, which is pretty fast, but far from being the fastest.

The MX500 is perfectly safe to ride, so you don’t need to worry much about this aspect. The handlebars are adjustable which makes it easy to maneuver. The main downside of this motorcycle is that it doesn’t have variable speed settings, and this is what sets it apart from MX650 as well as SX500.

Its 14’ and 16’ tires provide the rider with plenty of comfort even when going over very uneven and rough terrain. The brakes are very responsive and will make the bike stop on a dime.

The warranty is standard 90 days which is more than enough to know whether this vehicle is right for your children. Its price is around $450 which makes it a tad more expensive than

MX650. The electric Razor dirt bike charger is included in the price.

All in all, this model is without a doubt one of the best that Razor has to offer. The reasons that it got fourth place in this list is the non-variable speed setting, which is a big deal for a bike as powerful as this one, and for its unjustifiably high price (more expensive than MX650).

5. Razor MX400 – The Underperformer

Razor Electric MX350 Motocross

Rating: 71/100

What we liked
• 90-day warranty
• Comfortable to ride

What we didn’t like
• No shocks
• Not worth its price
• Smaller than it preceding model

Ok, now it’s time to talk about a bike that we didn’t really like. Its name is MX400, and it is essentially a newer and pricier version of MX350. How is it different from the latter? Let’s find out.

The main difference is the size, with the MX400’s dimensions being 24.5 x 45.5 x 10 inches, which is smaller than MX350. The weight of this bike is similar to the previous one, and it is 62.5 pounds.

The age recommendation, though, remains the same (13 years and above), which seems inappropriate to us as taller kids are going to have a problem with the low positioned seat. Its weight capacity is 140 pounds, but some users claim that the motor struggled to go up a ridge with a 90-pound kid on it.

This means that, in reality, it’s suitable for children under 10.

Don’t let the name fool you, as the wattage of the motor is 350 W, not 400 W. Its top speed is around 14mph, and the battery lasts for about 30 to 40 minutes which might be a small improvement compared to MX350. The charging time is as with all other models, close to 12 hours.

Similar to MX350, this model is easy to maneuver. It’s light, the handlebars are adjustable, and the twist throttle is excellent for kids. Brakes are on point, but no shocks and no double suspension makes the ride a bit bumpier than with more quality models.

The 90 limited warranty does not cover wear and tear, cables, tubes, or crash-induced damages. The price of this bike is close to $340, which makes it almost $100 more expensive than the MX350. This is the money that can buy you a higher-class used Razor electric dirt bike.

In case you wanted to ask why we didn’t like it, let us clarify a bit more. As you could have read from this review, there are almost no significant updates on this model compared to MX350, yet it is nearly $100 pricier.

We could not find any valid reason for it to be more costly than its predecessor, so we would not recommend it to you. Instead, go for the MX350, and you will be just fine.


As always, the time has to bring this article to an end. We packed in a lot of information for you today, and we realize that it might be hard to process it all at once, so that’s why we owe you a short recap of our top three products.

MX650, the winner of this roundup, earned its spot by being the most powerful and fastest dirt bike on the list while not compromising on quality and safety even a bit. This is a bike that was built to last, and we are sure that your child will be able to enjoy it for years to come.

A very close runner-up, the SX500 is another phenomenal bike. If you want something with a bit less power than MX650 but are willing to pay an extra few dollars, then this one is right for you.

The MX350 is ideal for kids younger than 10 (despite its advertised age recommendation), and we find it to be perfect for a child’s first motorized two-wheeler. Also, its low price is a big bonus.

Now, we would like to leave you with a few final words of advice. Razor is undoubtedly one of the best companies that make this sort of products, but not the only.

Make sure to do more reading and careful research before you decide who to give your money to. 

One other suggestion would be to pay a lot of attention to what people say about their experiences with the bike you are planning to buy. We put a lot of value into user review for our electric bike evaluations, and it is the same for electric dirt bikes.

Their reviews are probably the most trustworthy piece of information online, so do not neglect them.

And, that would be all for today. Until next time dear readers!
