Executive Summary
The GhostCat F4X Pro is a high-performance, full-suspension electric motorbike designed for thrill-seekers and off-road enthusiasts. It pushes the boundaries of the e-bike category with a colossal 60V powertrain, featuring a geared hub motor that peaks at over 3,000W and delivers a claimed 160+ Nm of torque. This is a machine built for raw speed and power, boasting a top speed of over 40 mph. Its robust build includes premium KKE suspension and powerful 4-piston hydraulic brakes to manage its performance. While it offers an unparalleled adrenaline rush, its primary focus is on off-road, private property use, as its power and speed far exceed standard e-bike classifications.
Key Takeaways:

Design & Ergonomics
The F4X Pro sports an aggressive and functional e-moto design, clearly inspired by off-road motorcycles. The full-suspension aluminum frame is built to withstand hard riding, and the extended two-seater saddle provides flexibility for rider positioning or carrying a passenger on private property. The ergonomics are centered around a commanding, active riding position with wide handlebars for maximum control. This is not a bike designed for casual pedaling; the full twist throttle and overall geometry make it clear that this is a machine you ride, not pedal.
Performance Review
Motor Performance (Peak W & Torque)
The performance of the F4X Pro is its defining characteristic. The 60V powertrain, paired with a motor peaking at over 3,000 watts, delivers absolutely blistering acceleration. With over 160 Nm of torque on tap, it can conquer the steepest off-road climbs and provides an adrenaline-pumping rush on flat ground. This level of power is far beyond typical e-bikes and places the F4X Pro in direct competition with lightweight electric dirt bikes.
Battery Life & Real-World Range Test
The bike is equipped with a massive 60V 25Ah battery, which translates to a huge 1500Wh capacity. This large energy reserve is necessary to feed the power-hungry motor. The advertised range of 30-45 miles in full-electric mode is a realistic estimate for aggressive off-road riding. For more conservative riding on trails, a range of 50+ miles is certainly possible. The high-capacity battery ensures that the fun lasts for extended off-road sessions.
Ride Quality & Handling
The premium KKE suspension system is a standout feature. The 120mm travel front fork and adjustable rear shock are designed to soak up large bumps, drops, and ruts found on off-road trails, providing a controlled and surprisingly smooth ride. The CST Scout all-terrain tires offer a good compromise between on-road grip and off-road traction. The bike's handling is geared towards high-speed stability, though its weight will make it a handful in very tight, technical singletrack.
Brakes
For a machine capable of 40+ mph, powerful brakes are paramount. The F4X Pro is appropriately equipped with 4-piston hydraulic disc brakes on large 203mm rotors. This setup provides the strong, reliable stopping power needed to manage the bike's extreme speed and weight, ensuring a critical margin of safety for high-performance riding.
Drivetrain
The GhostCat F4X Pro features a single-speed drivetrain. This is a practical choice for a high-power e-moto, as the immense power of the motor makes multiple gears largely redundant. The focus is entirely on throttle control, and the single-speed setup simplifies the bike, increases durability, and reduces maintenance, which is ideal for a machine intended for hard off-road use.
Pros & Cons
Pros
- Extreme Motor Power: 3300W peak output provides breathtaking acceleration and speed.
- High-Quality Suspension: KKE front and rear suspension offers excellent performance on rough terrain.
- Powerful 4-Piston Brakes: Provides the stopping power necessary for a high-speed vehicle.
- Large 1500Wh Battery: Offers substantial range for extended off-road rides.
- Durable Off-Road Build: Designed to withstand the rigors of aggressive riding.
Cons
- Not Street Legal: Explicitly for off-road/private property use only in most areas.
- Very Heavy: Difficult to transport and maneuver at low speeds.
- Impractical for Pedaling: Single-speed drivetrain and moto-style ergonomics make pedaling a non-factor.
- High Price Point: This level of performance comes with a significant investment.
Final Verdict
The GhostCat F4X Pro is for the adrenaline junkie with access to private land or dedicated off-road trails. It is a pure, unapologetic performance machine that blurs the line between an e-bike and a light electric dirt bike. If you are looking for a vehicle that delivers motorcycle-level thrills, can handle aggressive off-road riding, and you understand its legal limitations, the F4X Pro is a phenomenal choice. However, if you need a street-legal e-bike for commuting or casual rides, this is absolutely not the bike for you. The F4X Pro is a specialized hyper-bike for a very specific type of rider who prioritizes raw power above all else.

Frequently Asked Questions (FAQs)
Can I ride the GhostCat F4X Pro on the street? +
In most locations, no. The F4X Pro's motor power (exceeding 750W) and top speed (exceeding 28 mph) mean it does not qualify as a Class 1, 2, or 3 e-bike. It is generally considered an off-road vehicle and should only be ridden on private property or in designated off-road areas. Always check your local laws.
How does the F4X Pro compare to a Sur-Ron or Talaria? +
The F4X Pro occupies a space between high-power e-bikes and dedicated electric dirt bikes like the Sur-Ron. While it has more power than almost any "e-bike," a Sur-Ron typically has a more advanced mid-drive motor and a more dirt-bike-specific frame geometry, making it more capable on highly technical terrain. The F4X Pro is a powerful all-terrain e-moto, while a Sur-Ron is a lightweight electric dirt bike.
Is this a good bike for a beginner? +
No. The extreme acceleration and high top speed make the F4X Pro unsuitable for inexperienced riders. It demands respect and should only be ridden by those comfortable with high-performance motorized vehicles.
Can you pedal the F4X Pro? +
While it has pedals, the bike is not designed to be pedaled. The single-speed gearing and rider ergonomics are optimized for throttle use. The pedals are primarily included for legal classification purposes in some areas and are not a practical means of propulsion.
