If you’ve ever dreamed of a vehicle that blends the raw power of a mini dirt bike with the legal convenience of an e-bike, your dream just rolled into reality—and it’s called the Ghostcat F4X.
Forget everything you thought you knew about electric bikes. The Ghostcat F4X isn’t your average commuter cruiser or fitness-focused pedal-assist machine. This is a high-octane, throttle-only beast wrapped in sleek, aggressive styling that turns heads, crushes trails, and blurs the line between e-bike and e-moto.
After riding it around Colorado’s legendary Lake Dylan trail—through rain, rocky off-road sections, steep climbs, and sweeping S-curves—we’re ready to deliver the most honest, detailed, and human-centered review of the Ghostcat F4X you’ll find anywhere.
Let’s dive in.
First Impressions: A Fusion of Form and Function
From the moment you lay eyes on the Ghostcat F4X, one thing becomes clear: this isn’t trying to be subtle.
With massive 20x4-inch Maxxis Maxx Venture tires, dual 120mm KKK suspension forks, a 2200W Hangtech motor, and a 60V 25Ah LG battery, the F4X looks more like a scaled-down electric motocross bike than a traditional e-bike. And that’s exactly the point.
The design screams performance. The front features a plastic fairing with the Ghostcat logo, a star-union LED headlight (one of the brightest we’ve tested), and a minimalist cockpit with a full twist throttle and XOD hydraulic brake controls. There’s no clutter—just clean lines, purposeful components, and a vibe that says, “I’m here to have fun.”
Even the pedals feel like an afterthought—but that’s intentional. More on that later.
Power & Performance: 40+ MPH in 22 Seconds? Yes, Please.
Let’s cut to the chase: How fast is it?
On a cold 50°F morning, with a rider weight of ~200 lbs and a fully charged 66.7V battery, the Ghostcat F4X hit 41 mph—and held it.
Here’s the acceleration breakdown:
- 0–10 mph: 1.72 seconds
- 0–20 mph: 4.05 seconds
- 0–30 mph: 7.77 seconds
- 0–40 mph: 17.97 seconds
- 0–41 mph: 22.83 seconds
That’s superbike-level acceleration for an 86-lb vehicle. And it’s not just fast in a straight line—it climbs steep hills at 32+ mph without breaking a sweat, thanks to 160 Nm of torque from the Hangtech rear hub motor.
The 55A controller paired with the 60V LG battery delivers consistent, responsive power. During our ride, we saw peak outputs of 3,234W—just shy of the advertised 3,300W peak, which is impressive in real-world conditions.
Ride Quality: Plush, Playful, and Surprisingly Capable Off-Road
Despite its compact size, the F4X handles like a dream.
Suspension That Actually Works
The dual KKK suspension system (front and rear) offers 120mm of travel with adjustable compression and rebound. On chunky, rocky trails that would rattle your teeth on a rigid e-bike, the F4X absorbs impacts like a champ. We even caught air off a small bump—unintentionally—and landed smoothly.
Tires That Grip Like Glue
The Maxxis Maxx Venture 20x4” tires are a game-changer. Unlike the generic CST BFT tires found on most fat-tire e-bikes, these use a soft, grippy polymer compound with deep, aggressive treads. They corner confidently, even on wet, muddy trails, and provide excellent traction on loose gravel.
Braking Power That Inspires Confidence
Equipped with 203mm rotors and 4-piston hydraulic brakes front and rear, stopping power is exceptional. Whether you’re bombing downhill at 35 mph or navigating tight switchbacks, the brakes respond instantly and modulate beautifully.
💡 Pro Tip: The brake and throttle are reversed (left-hand brake, right-hand throttle)—just like on a dirt bike. This setup makes it easier to do wheelies (yes, really) and feels natural once you adjust.
Range Reality Check: How Far Can You Really Go?
Ghostcat claims 25–35 miles of range on throttle-only mode. After a 23.77-mile loop around Lake Dylan—with constant throttle use, hill climbs, and off-road detours—we ended with 53.8V remaining (out of a 66.7V max).
Given that the battery cuts off around 49V, we estimate ~30 miles of real-world range under aggressive riding conditions. That’s spot-on with Ghostcat’s claim—a rarity in the e-bike world, where inflated range estimates are all too common.
For context:
- Average speed: 20.4 mph
- Total ride time: 1 hour 10 minutes
- Conditions: Cold (50°F), light rain, mixed terrain
Cold weather and rain slightly reduce efficiency, so in ideal conditions, 35 miles is absolutely achievable.
Design & Practicality: Sleek, But With Quirks
What We Loved
- Stunning aesthetics: The F4X stands out in a sea of cookie-cutter fat-tire e-bikes.
- Dual-passenger ready: Comes with rear foot pegs and a long saddle—perfect for sharing the fun.
- Bright, readable display: Crisp LCD screen with USB port, easy to read in direct sunlight.
- Ultra-bright headlight: One of the brightest we’ve seen on any e-bike—great for dawn/dusk rides.
- US-based customer support: Ghostcat’s team actually answers the phone and helped early adopters upgrade controllers for free.
What Could Be Improved
Pedals Are Purely Cosmetic
Let’s be honest: you can’t realistically pedal this bike. The single-speed drivetrain, high bottom bracket, and cramped geometry make pedaling feel like “a clown trying to ride a unicycle.” It’s clearly there only for legal classification—so you can ride on bike paths in places like California or Colorado.Throttle Delay & Jerkiness
There’s a noticeable stutter or lag when you first twist the throttle from a stop. It jerks slightly before launching. Not dangerous, but not smooth.Poor Fenders
The rear fender is tiny and ineffective—we got soaked from wheel spray. The front fender also wobbles side-to-side due to loose mounting.
- Battery Straps Over the Logo
The battery uses external straps to prevent shifting—a functional fix, but it covers the sleek Ghostcat branding. A cleaner integrated solution would be better.
No Official Water Resistance Rating
We rode in light rain with no issues, but without an IPX rating, it’s hard to know the limits. An IPX5 would give peace of mind.Mediocre Included Tools
Assembly requires installing handlebars, kickstand, suspension linkages, and fenders. The included tools are soft and prone to stripping bolts—bring your own.
Who Is the Ghostcat F4X For? (And Who Should Skip It)
✅ Perfect For:
- Thrill-seekers who want e-moto performance without a license or registration.
- Trail riders in states that require pedals for legal trail access (like Colorado).
- Urban adventurers who crave speed, style, and off-road capability.
- Couples or friends who want to share rides (thanks to the dual-seat design).
- Early adopters who appreciate US-based support and iterative improvements.
❌ Not For:
- Commuters needing pedal-assist for exercise or efficiency.
- Tall riders (over 6')—the cockpit feels cramped.
- Range maximizers—this is a throttle-first machine, not an efficiency king.
- Rain riders—without a water resistance rating, heavy downpours are risky.
Final Verdict: A Fun-First Machine That Delivers
The Ghostcat F4X isn’t trying to be everything to everyone—and that’s its greatest strength.
It’s not an e-bike in the traditional sense. It’s a throttle-powered joy machine disguised as one, designed for riders who prioritize grins per mile over pedal strokes.
With 40+ mph speeds, plush suspension, premium Maxxis tires, beefy brakes, and jaw-dropping looks, it’s one of the most unique and exhilarating electric rides we’ve tested.
Yes, it has quirks—the pedal setup, throttle lag, and fender flaws are real. But none of them ruin the experience. In fact, they’re easy to overlook when you’re flying down a forest trail, wind in your face, with a hawk circling overhead.
If you want an e-bike that feels like a pit bike, looks like a concept vehicle, and rides like pure freedom—the Ghostcat F4X is calling your name.

The Bottom Line
The Ghostcat F4X proves that electric mobility doesn’t have to be boring. It’s a bold, playful, and surprisingly capable machine that redefines what an “e-bike” can be.
Whether you’re carving mountain trails, cruising lakeside paths, or just want to feel like a kid again, this bike delivers pure, unfiltered fun—with just enough legal compliance to keep the authorities off your back.
Rating: 9/10
Docked one point for pedal impracticality and fender flaws—but the joy factor more than makes up for it.
