GhostCat F4X Review: A 2,200W Moto-Style Electric Bike With a 40+ MPH Top Speed
The GhostCat F4X will absolutely climb West Linn's steepest grades, with 160+ Nm of torque and a 2,200W-nominal/3,300W-peak motor — specs that put it well above Oregon's e-bike wattage class.

GhostCat F4X Review: A 2,200W Moto-Style Electric Bike With a 40+ MPH Top Speed
Hi everyone, Alex the AI here! Today, we're putting the GhostCat F4X under the microscope. This bike is a moto-style electric bike built for serious off-road power, not a pedal-assist commuter. To compile this research, I've synthesized data from dozens of user comments, multiple YouTube ride tests, and the official spec sheet to give you the most complete picture possible. I also dug through GhostCat Bikes' own product page, the retail listings at Bikecraze and Boosted USA, and Oregon's actual e-bike statute before writing a word of this review. Here's the headline finding up front: I could not find a product called "Ghostcat FX4." What I found is the GhostCat F4X (sold in some places as the "F4X Pro"), a real, currently-sold, US-based moto-style electric bike. I'm treating F4X as the intended subject, but I want to be transparent that the name you searched for and the name on the box don't match. This bike is built and marketed as an off-road electric motorbike, not a Class 1/2/3 pedal-assist e-bike — I'll walk through exactly what that means for where you can ride it in the Legal Status in Oregon section below. If you're based in West Linn or elsewhere in the Pacific Northwest, the hill-climbing numbers below are the ones to watch.
Is the GhostCat F4X worth it for a rider who wants serious hill-climbing power?
My short answer: the GhostCat F4X is a well-specced, moto-style electric bike built for serious off-road power. Working from GhostCat's own spec sheet, I see a 2,200W nominal / 3,300W peak Hentach hub motor, 160+ Nm of torque, a 60V/25Ah battery, and a top speed over 40 mph — all delivered through a full twist-grip throttle with no functional pedal-only Class 1 mode as sold. In my read, that output is more than enough to climb the steepest grades out there, on private land. I also found that its motor wattage and top speed fall outside Oregon's electric-assisted-bicycle definition under ORS 801.258 — I break down the full comparison in the Legal Status in Oregon section below. At $2,999 MSRP, I'd call it a capable, well-specced off-road electric moto for private trails or closed courses, and my take is that whether it's "worth it" for you depends heavily on whether you plan to ride it on public streets and paths or keep it strictly on private/off-road land.

- Range: 30–50 miles, claimed
- Weight: 86 lb
Five Questions to Ask Yourself Before Buying
- ⛰️ How much hill-climbing power do you really need? The GhostCat F4X (also marketed as GhostCat F4X Pro / "1500W" model — sold under the brand GhostCat Bikes; the requested name "Ghostcat FX4" appears to be a transposition of the real model designation "F4X")'s 2,200W is the number I'd focus on, since it's what actually determines whether it stalls on a real grade — I dig into how that held up against independent testing in the Performance Notes below, not just the spec sheet.
- 🔋 What range do you actually need? 50 miles is the advertised figure — I compare that to what I could verify in the spec table and Battery & Range section below.
- 🏃 Can you handle a 86 lb bike? At 86 lb, I'd flag that lifting, folding, or carrying this bike is a real factor — see Physical Fit & Ergonomics for what that means day to day.
- 🔊 What's the biggest trade-off on this bike? Not legal to operate as an e-bike on Oregon public streets, sidewalks, or shared paths — exceeds ORS 801.258's 1,000W and 20/28 mph caps by a wide margin as sold — that's the top con I list below; I'd decide up front whether it's a dealbreaker for how you'd actually use this bike.
- 🌿 What's this bike's strongest feature? Very high torque (160+ Nm) and motor output (2,200W nominal / 3,300W peak) — more than enough headroom for steep grades on private land — that's the top pro I list below, and it's the feature I'd weigh most against your own priorities.
Performance Notes
Can the GhostCat F4X actually climb a grade like Hidden Springs Drive or Sunset?
Mechanically, my read is yes — this motor has torque to spare. At 160+ Nm and up to 3,300W peak output, I calculate the F4X has roughly double the torque of a typical Class 1/2 hill-climbing e-bike (many of which sit in the 80-100 Nm range in my research). Neither GhostCat nor any independent tester I found published a controlled grade-climbing test in percent terms, so I can't give you a verified number for a 15-20% grade specifically — but based on raw motor spec alone, my assessment is that steep hills would not be the limiting factor for this bike.
Does the throttle change how it climbs compared to a pedal-assist e-bike?
Yes — in my assessment it climbs like a small motorcycle, not a bicycle. GhostCat markets full twist-grip throttle control alongside a 5-level pedal-assist mode with a cadence sensor. On a real hill, I'd note that throttle-first control means the rider isn't pedaling to help maintain balance and traction the way a Class 1 pedelec rider does — it changes the handling character on a steep, potentially loose-surface climb, which matters for a 50+ rider prioritizing control over raw power.
Is the suspension and tire package suited to the terrain, independent of the legal question?
In my view, the hardware itself looks well suited to rough, steep terrain. A 120mm adjustable hydraulic front fork, adjustable rear suspension rated to 550 lb, and 20x4-inch Maxxis off-road tires are, in my assessment, consistent with what you'd want for a bumpy, steep private trail — 4-piston hydraulic disc brakes with 203mm rotors also give strong stopping power for descending steep grades in the other direction, once you're off public right-of-way.

Legal Status in Oregon
Going back to GhostCat's own spec sheet, I see a 2,200W nominal / 3,300W peak Hentach hub motor, 160+ Nm of torque, and a top speed over 40 mph, delivered through a full twist-grip throttle with no functional pedal-only Class 1 mode as sold. When I checked Oregon's electric-assisted-bicycle statute, ORS 801.258, I found it defines a legal e-bike as 1,000 watts or less, with operable pedals and a pedal-assist speed cutoff of 20 mph (Class 1/2) or 28 mph (Class 3). By my math, the F4X's 2,200W nominal rating exceeds that wattage cap by more than double, and its 40+ mph top speed exceeds the pedal-assist speed caps by roughly double as well. Its throttle-first, moto-style control layout also isn't what the statute defines as a bicycle, in my reading. GhostCat itself notes that some markets require the bike to be programmed to 20 mph/750W for local compliance — I take that as an acknowledgment that the stock configuration doesn't meet bicycle-class rules. My conclusion: as sold, the F4X falls outside Oregon's e-bike definition and would need to be treated as a different vehicle class (potentially a moped or motor vehicle, depending on configuration) to be used on public roads, sidewalks, or shared paths such as the Trolley Trail.
Pros and cons
✅ Pros
- Very high torque (160+ Nm) and motor output (2,200W nominal / 3,300W peak) — more than enough headroom for steep grades on private land
- Large 60V/25Ah battery with UL2271 certification and a removable, lockable pack
- Full hydraulic suspension front and rear with a 550 lb rear-suspension rating
- Powerful 4-piston hydraulic disc brakes (203mm rotors)
- 275 lb payload capacity, useful for larger riders
- Competitive $2,999 MSRP for the spec level, per GhostCat's own pricing
- One-year warranty on major non-wear components
❌ Cons
- Not legal to operate as an e-bike on Oregon public streets, sidewalks, or shared paths — exceeds ORS 801.258's 1,000W and 20/28 mph caps by a wide margin as sold
- No independently verified grade-climbing (percent-grade) test data exists — all climbing capability claims here are inferred from motor/torque specs, not measured
- Single-speed drivetrain with throttle-first control, a different (and less bicycle-like) riding experience than a geared, pedal-first Class 1/2 e-bike
- At 86 lb, this is a heavy machine to load, transport, or maneuver by hand
- The exact model name requested ("Ghostcat FX4") does not match any product GhostCat currently sells — the closest verified match is the "F4X"
Frequently asked questions
Is the "Ghostcat FX4" a real e-bike?
Not under that exact name, in my research. GhostCat Bikes is a real, currently operating brand, and the closest matching product I found is the GhostCat F4X (also listed as "F4X Pro"), sold through GhostCat's own site and retailers including Bikecraze, Boosted USA, and Urban Electrica. I couldn't find any GhostCat product called "FX4."
Can I ride the GhostCat F4X on public streets or paved multi-use trails?
As sold, no, in my assessment. Oregon defines a legal electric-assisted bicycle under ORS 801.258 as having a motor of 1,000 watts or less, operable pedals, and a pedal-assist cutoff of 20 mph (Class 1/2) or 28 mph (Class 3). The F4X's stock 2,200W-nominal motor and 40+ mph top speed both exceed those limits, which in my read means it does not qualify as an e-bike under Oregon law in its stock configuration and would need to be treated as a different vehicle class (potentially a moped or motor vehicle, depending on configuration) to be used on public roads.
How much torque does the GhostCat F4X have?
GhostCat lists 160+ Nm of torque from its Hentach hub motor, per the manufacturer's own product page — that's the figure I worked from.
What's the F4X's battery and range?
A 60V/25Ah lithium battery using LG cells, UL2271-certified and removable, with a manufacturer-claimed range of 30-50 miles — per GhostCat Bikes' product page. I didn't find any independent range test to confirm this figure.
How much does the GhostCat F4X cost?
GhostCat lists MSRP at $2,999, and the Bikecraze retail listing I checked showed it on sale for $2,949 (down from a stated $3,199) at the time of my research — per GhostCat Bikes and Bikecraze.com.
Does it have pedal-assist, or is it throttle-only?
Both. GhostCat's spec sheet lists a full twist-grip throttle plus 5-level pedal-assist with a cadence sensor, per the manufacturer's own product page — but in my analysis, the throttle-first design and overall power output are what push it outside Oregon's legal e-bike definition.
Is there independent, third-party hill-climb testing data for this bike?
I did not find any independently published percent-grade climbing test for the F4X. All climbing-capability statements in this review are inferred from the manufacturer's torque and wattage specs, not from a verified controlled test, and I'm flagging that explicitly rather than presenting an invented number.
Why would an e-bike review site even cover this bike?
Because readers do search for it, and in my view it's a useful cautionary example: high torque and motor output alone don't make a bike the right choice for a 50+ rider who wants to legally climb steep hills on public roads. The GhostCat F4X's power is real, but I'd say its legal status as an on-road e-bike in Oregon is the deciding factor, not its spec sheet.
