The EKXBIKE X21MAX is a high-power electric dirt bike designed around an 8,000W peak motor, 60V 30Ah battery, full suspension, 19-inch off-road tires, and a claimed top speed of 60 MPH. It is aimed more toward experienced adult and teen riders than complete beginners.
The X21MAX stands out because of its combination of high peak power, claimed 240 N·m torque, large battery, full suspension, and 330-pound maximum load. At the same time, some specifications vary between marketplace listings, particularly the bike’s weight, so buyers should verify the exact configuration before ordering.
One owner with several years of electric dirt-bike experience reported approximately 60 MPH on a flat trail, strong hill-climbing ability, and good suspension performance over rocks and roots. That is useful real-world evidence, but it represents one rider’s experience rather than a standardized test.

Motor & Performance
The X21MAX is built around a 3,000W rated motor with an 8,000W peak power claim. The listing also gives a claimed 240 N·m of peak torque and a top speed of approximately 60 MPH.
That puts the X21MAX firmly in the high-performance category of electric dirt bikes.
For an adult rider looking for a bike that can handle faster trail riding and steep terrain, the combination of high peak power and high claimed torque is one of the X21MAX’s main selling points.
However, the 8,000W and 60 MPH figures should be viewed as claimed specifications. Actual performance can change depending on rider weight, battery charge, terrain, temperature, tire pressure, and riding conditions.
How does the X21MAX perform on hills?
One owner with around three years of electric dirt-bike experience reported that the X21MAX was the most powerful electric dirt bike they had owned. They also reported approximately 240 N·m of torque, around 60 MPH on a flat trail, and the ability to handle an approximately 40-degree incline.
That report is interesting because it gives some context around the bike’s real-world performance. However, a single rider’s experience should not be treated as a standardized climbing test.
For our review, we therefore separate the manufacturer’s performance claims from owner-reported results.
Battery & Range
The X21MAX uses a 60V 30Ah lithium battery.
Using the standard voltage × amp-hour calculation:
60V × 30Ah = 1,800Wh
So the battery contains approximately 1.8 kWh of nominal energy.
The listing claims 60+ miles of range, but that number should be treated carefully.
Actual range can be affected by:
- Rider weight
- Riding speed
- Terrain
- Hills
- Acceleration
- Temperature
- Tire pressure
- Battery condition
- Riding mode
- How much throttle is used
A rider traveling aggressively on rough trails is unlikely to get the same range as someone riding more slowly on relatively flat terrain.
Is the X21MAX battery removable?
Yes. The X21MAX listing describes the battery as removable and lockable, which can make charging more convenient when the bike cannot be parked directly beside a suitable power outlet.
Charging time
We did not find sufficiently reliable evidence to assign a specific charging time to the X21MAX. Rather than invent a number, we recommend checking the current Amazon listing and manufacturer’s documentation for the exact charger and charging specification supplied with your configuration.
Suspension & Brakes
The X21MAX uses a full-suspension setup, including a front suspension system and rear shock.
That is important for an electric dirt bike intended for rough trails because the suspension needs to deal with rocks, roots, uneven ground, and repeated impacts.
One experienced owner specifically reported riding the X21MAX over rocks and roots and described the full suspension as performing well in those conditions.
Again, this is an individual owner experience rather than a controlled suspension test.
Hydraulic Brakes
The X21MAX is listed with hydraulic disc brakes, providing the type of braking system expected on a high-power off-road bike.
The product information also identifies hydraulic suspension components and large disc rotors.
Because the bike is capable of high claimed speeds, brake condition is particularly important. Riders should inspect the brake system, pads, rotors, lines, and controls regularly.
Size, Weight & Rider Fit
The X21MAX is a full-size electric dirt bike rather than a compact electric bicycle.
The available product information gives a maximum load of approximately 330 pounds and a recommended rider-height range of roughly 5’5″ to 6’5″.
The weight is less straightforward.
We found:
- Approximately 110 lb in Amazon product information
- Approximately 123 lb in other product information
Because these figures conflict, we recommend treating the X21MAX as approximately 110–123 lb depending on the exact listing or configuration.
That difference is worth checking before purchasing, especially if you plan to transport the bike frequently.
Is the X21MAX suitable for heavier riders?
The listed 330-pound maximum load gives the bike a relatively high stated capacity.
One owner also reported using the bike as a larger rider and described its performance positively. However, maximum load is not the same as a recommendation that every rider at that weight will experience identical handling or suspension performance.
Rider height, riding experience, terrain, and comfort should all be considered.
19-Inch Off-Road Tires
The X21MAX uses 19-inch off-road wheels with 70/100-19 tires according to the product information.
This gives the bike a more traditional dirt-bike appearance and setup than many fat-tire electric bicycles.
The knobby tire design is intended for unpaved terrain, but tire pressure and condition can have a significant effect on traction.
Before riding, check:
- Tire pressure
- Tread condition
- Spoke tension
- Wheel alignment
- Brake clearance
For aggressive trail riding, these checks become particularly important.
Features
The X21MAX includes several features aimed at off-road riding.
7-Speed Drivetrain
The listing identifies a 7-speed drivetrain, giving riders multiple gear options.
However, some Amazon product-information fields contain contradictory drivetrain terminology, so buyers should verify the exact configuration of the current listing.
LCD Display
The X21MAX uses an LCD display for riding information.
The researched instructions also indicate that the display can be switched between MPH and km/h.
Removable & Lockable Battery
The battery can be removed from the bike and is described as lockable.
LED Lighting
The bike includes LED lighting, including a front headlight.
Full Suspension
The combination of front and rear suspension is one of the more important features for its intended off-road use.
Hydraulic Disc Brakes
Hydraulic disc brakes provide the braking system expected for a bike in this power and speed category.
Customer Review Evidence
Customer evidence is particularly useful with the X21MAX because the bike’s headline specifications are aggressive.
Owner Report: Experienced Rider
One owner reported having approximately three years of electric dirt-bike experience and described the X21MAX as the most powerful e-dirt bike they had owned.
The rider reported:
- 8,000W peak power
- Approximately 60 MPH on a flat trail
- 240 N·m claimed torque
- Approximately 40-degree climbing ability
- Full suspension over rocks and roots
Most importantly, the rider explicitly described the X21MAX as not a beginner bike.
That report is useful because it comes with riding experience and specific observations, but it remains an individual experience rather than an independent laboratory test.
Owner Report: Assembly & Easier Trails
Another owner reported that the bike was easy to assemble, arrived well packaged, and rode well on easier trails and roads.
Again, this is an individual experience rather than evidence that every X21MAX will arrive or perform identically.
What to Watch For
Specification differences
The biggest research issue with the X21MAX is that some specifications vary between product-information fields.
The clearest example is weight:
Approximately 110–123 lb depending on source/listing.
Rather than hiding that difference, we recommend checking the exact Amazon configuration before purchasing.
High power
An 8,000W peak claim and 60 MPH claimed speed put the X21MAX well beyond the typical entry-level electric bike category.
This isn’t necessarily a negative, but it means riders need to be comfortable controlling a high-powered off-road machine.
Range claims
The 60+ mile range is a claim rather than a standardized independent test.
If range is particularly important to you, consider your expected speed, terrain, rider weight, and riding style rather than using the headline number alone.
Availability
The Amazon listing we researched was previously shown as unavailable. Amazon availability can change, so verify the current listing before relying on the price or stock status.
Street legality
We would not assume that the X21MAX is street legal.
The presence of an electrical certification claim in a marketplace listing does not automatically establish road legality in every state, country, or jurisdiction.
Check your local requirements for registration, equipment, licensing, age restrictions, and where the bike can legally be operated.

Who Is the X21MAX For?
The X21MAX is primarily interesting for adult and experienced riders looking for a high-power electric dirt bike.
It may make sense for riders who prioritize:
- High peak power
- High claimed torque
- Faster trail riding
- Full suspension
- Large battery capacity
- 19-inch off-road wheels
- Higher rider capacity
- Off-road recreational riding
- Private-property riding
It is less naturally suited to someone looking for a simple, low-speed beginner bike.
The owner evidence we reviewed also supports treating the X21MAX as an experienced-rider-oriented machine, rather than positioning it as a beginner model.
X21MAX vs. TX1
The TX1 is one of the most natural comparisons because both are EKX electric dirt bikes with a 60V 30Ah battery and 19-inch off-road configuration.
| Specification | EKXBIKE X21MAX | EKX TX1 |
|---|---|---|
| Rated Power | 3,000W | 3,000W |
| Peak Power | 8,000W | 7,000W |

| Battery | 60V 30Ah | 60V 30Ah |
| Calculated Energy | 1,800Wh | 1,800Wh |
| Claimed Range | 60+ mi | Up to 60 mi |
| Maximum Load | 330 lb | 330 lb |
| Wheels | 19″ | 19″ |
| Riding Focus | Trail / off-road | Trail / light off-road |
Based on the published figures, the X21MAX has higher claimed peak power, torque, and top speed, while the two bikes have similar battery capacity and maximum load.
For a detailed comparison, the important factors go beyond wattage: weight, suspension setup, rider experience, availability, warranty, parts support, and the specific configuration being sold should also be checked.

Final Thoughts
The EKXBIKE X21MAX is positioned as a high-performance electric dirt bike rather than a basic recreational e-bike.
Its headline specifications are substantial: 8,000W peak power, 240 N·m claimed torque, 60 MPH claimed top speed, a 60V 30Ah battery, full suspension, hydraulic disc brakes, and 19-inch off-road tires.
The bike’s strongest documented appeal is its combination of high power and off-road hardware. Owner feedback also provides some encouraging real-world context, including reports of strong trail performance, hill climbing, and suspension performance.
At the same time, buyers should pay attention to the details behind the headline specifications. Weight varies between sources, the 60+ mile range is a claim rather than a standardized test, charging information is not sufficiently verified, and marketplace listings can contain contradictory product fields.
For an experienced adult rider looking for a powerful electric dirt bike, those details are worth investigating before purchase.
