The bikes are truly dirt bikes, and the steel frame makes them last longer and handle rough terrains. Thus, you can take these bikes with you on adventures and vacations without the fear of getting them damaged.

However, the Razor SX500 gives a bulkier look when it comes to the overall look, while the Razor MX500 gives a slim and sleek look.

As we always like sleek and slim electric scooters and bikes, we prefer the Razor MX500 in this case. However, the Razor SX500 isn’t heavier or ugly. It comes with unique geometry and graphics, inspired by the most popular Motorcross rider, Jeremy McGrath. The choice depends on your preference.


Razor MX500.

Using Time

As dirt bikes are usually meant for adventures and fun purposes instead of going to the office or school, they typically have less using time and a much longer charging time.

Luckily, both the Razor MX500 and SX500 dirt bikes have a using time of 40 minutes.

Compared to other electric scooters, this using time is much better. Generally, we see electric scooters will a using time between 15 and 30 minutes. Thus, the 40 minutes using time is a bonus for you to enjoy your day on the hills and go on adventures.

Although the company mentions providing 40 minutes using time, it can be extended if you are lightweight. The rider’s weight also depends on battery life. Thus, light individuals can enjoy a longer using time, approximately an hour.


As both the Razor MX500 and SX500 have the same using time, it’s a tie!

Motor Power

As dirt bikes have to handle rough terrains and bumpy hills, we expect them to have robust motors that could handle all of them. The scooter’s performance depends on the motor, and a powerful motor means that it will work well in harsh conditions without decreasing the scooter’s life.

The Razor MX500 has a high-torque motor of 650W, which exceptionally delivers high power to operate the scooter at your desired speeds. This power is better than many other electric scooters in the market, as most of them have much less motor power.

The Razor SX500 also comes with a high-torque and powerful motor, delivering power of 500W to the dirt bike. Although less than the Razor MX500, this motor power is enough to help you enjoy a comfortable ride.

Thus, both the dirt bikes have powerful motors which allow them to handle rough terrains so that you can enjoy a comfortable and safe ride.


Razor MX500.


Both the Razor MX500 and SX500 dirt bikes have lead-acid batteries that are included in the package.

When compared to other electric scooters, they have lithium-ion batteries, which are very common among all manufacturers.

Lead-acid batteries are less costly but require regular maintenance. That is why most manufacturers use lithium-ion batteries to reduce replacement and maintenance cost.

Thus, the lead-acid batteries may be the reason for the lower price of both the electric scooters.


As both the electric scooters have lead-acid batteries, it’s a tie!


Adventure-loving kids and teenagers always consider the speed of the electric bike as a priority. If you are one of them, these electric scooters won’t disappoint you!

Both the MX500 and SX500 operate at exceptionally high speeds and can reach top speeds of 15 mph. This speed is much higher than many other electric scooters, which have limited speeds of 10 mph and less.

Thus, the speed of both electric scooters is the same and high enough for you to enjoy a thrilling ride.

With less user weight and when fully charged, the dirt bikes can reach even higher speeds.

However, these speeds are much higher on electric scooters. Thus, we recommend riding at lower speeds and wearing a helmet and knee and elbow pads for safety.


As both the electric scooters have the same top speed, it’s a tie!

Weight and Weight Capacity

The weight of the dirt bike decides its convenience for the users. Many electric scooters are lightweight with a folding mechanism so that you can carry and store them easily.

However, dirt bikes follow a somewhat different mechanism.

They don’t usually come with a folding mechanism, and the seat and large tires make them heavy.

The Razor MX500 dirt bike weighs 50802 Grams (50.8 kg). This weight seems heavy, and you cannot carry or store this dirt bike in small places. However, you can park it inside the house.

Similarly, the Razor SX500 dirt bike weighs 98 pounds (44.4kg). Although it weighs much less than the Razor MX500, it is still heavier than other electric scooters.

The heavier weight of dirt bikes is okay because they have to handle extremely rough surfaces. Thus, the robust frame and tires and battery accounts for heavier weight.

When it comes to weight capacity, it is the same for both dirt bikes. The Razor MX500 and SX500 can accommodate rider weight up to 175 lbs. (79 kg).

In our opinion, this weight capacity is less than other electric scooters. Thus, we do not recommend them for heavy-weight and obese adults.

If you weigh less, you can enjoy rides at higher speeds with longer battery life.


Razor SX500.


For added convenience, both the Razor MX500 and SX500 come with a twist-grip throttle. This feature makes it easy to handle and control, especially for children and teenagers.

With the throttle control, you can quickly operate the dirt without getting into complicated features. In this way, all your focus will be on the road, and you will enjoy a fun and smooth ride.


As both the dirt bikes have a twist-grip throttle, it’s a tie!

Braking System

When riding on bumpy roads and hilly areas, the braking system plays a significant role.

Luckily, both the Razor MX500 and SX500 have dual disc braking systems, making them highly efficient and safe dirt bikes.

The brakes on both the scooters are hand-operated, making you free from getting into complicated settings while riding the dirt bike.

Although both the dirt bikes have a dual rear braking system, we feel it is better to include a front braking system for added safety.

However, the rear braking system is also enough. It helps slow down the ride so you can land smoothly instead of suddenly stopping with a bump.


As both the dirt bikes have the same braking system, it’s a tie!


As the dirt bikes are meant for off-road adventures and riding on bumpy areas, we expect them to have extra-rugged and thick tires.

Luckily, they come up to our expectations!

The Razor MX500 has different-sized tires, the front tire measuring 16-inch and the rear one 14-inch. This tire size is much better than other electric scooters.

The pneumatic nature of the tires and the robust pattern ensures the perfect grip with the ground. Thus, we can call it an all-terrain dirt bike due to the rugged tires.

On the other hand, the Razor SX500 comes with 10-inch tires.

The tire size is less than the Razor MX500 but more than standard electric scooters, with a limited tire size of 6.5-inch. Thus, both the dirt bikes can easily conquer off-road and bumpy roads and hills while ensuring a smooth and comfortable ride.


Razor MX500.


Many electric scooters might not have suspension, but it is a helpful feature to add. However, it may account for the higher price-point of the scooter.

We like that both the Razor MX500 and SX500 dirt bikes have suspension.

But wait.

Both of them have dual suspension!

The dual suspension is definitely one of the best features to add as it makes the scooter much safer than others.

As the dirt bikes tackle bumpy terrains, the dual suspension plays a significant role in providing a smooth and comfortable ride.

They absorb the impact and shocks that could disturb you can cause you to lose balance. Thus, you stay safe and enjoy a comfortable ride regardless of the terrain you are riding.


As both the dirt bikes have dual suspension, it’s a tie!

Charging Time

The charging time of the electric scooter determines whether it is ideal for long-distance travelling or not. However, that does not apply to dirt bikes.

Dirt bikes are most commonly meant for outdoor adventures and fun purposes instead of commuting long distances.

Both the Razor MX500 and SX500 dirt bikes have an equal charging time of 12 hours. It seems too much, but many off-road scooters and dirt bikes have the same charging time.

As they offer 40 minutes using time and a 12-hour charging time, we usually recommend them for fun purposes and adventures.


As both the dirt bikes have the same charging time, it’s a tie!


The water-resistance capability plays a significant role in the durability and practicality of an electric scooter.

Unfortunately, the Razor MX500 and SX500 do not have any water-resistance capability.

Thus, we can say that they aren’t suitable for all weather conditions.

If you ride it in the rain or mud, water and dirt will seep into the bike and damage its internal parts.


As both the scooters aren’t water-resistant, it’s a tie!


Bluetooth is a new feature primarily seen in advanced hoverboards and electric scooters to provide a fun and thrilling ride. Most of them also offer app compatibility so that you have all the information in front of you.

However, Razor MX500 and SX500 do not have Bluetooth or app compatibility.

In our opinion, it isn’t something bad. You won’t have to spend time getting into complicated features and understanding them.

As both the dirt bikes come with hand-operated features, they make it super-easy to ride and learn, especially for children and teenagers.

In this way, you will focus on your ride and enjoy it to the full!


As none of the dirt bikes has Bluetooth, it’s a tie!

Recommended Age

Both the Razor MX500 and SX500 have a recommended age of 14 years and above.

It means that they aren’t suitable to ride for children below 14 years of age.

Teenagers and adults can easily ride them and enjoy a thrilling ride at high speeds.

However, if you want your child to ride these dirt bikes, make sure that they ride them under your supervision, and with all the safety precautions, like a helmet, knee and elbow pads, etc.


As both the dirt bikes have the same recommended age, it’s a tie!
