Mokwheel Onyx Review 2025: 1300W Mid-Drive Fat Tire E-Bike with Full Suspension
Last Updated on January 14, 2026 by Kristina
Mokwheel’s brand-new Onyx Series – available as the classic Onyx and the step-through Onyx ST—brings serious power and precision to the all-terrain e-bike scene. With a 750 W mid-drive motor (1,300 W peak) and 210 Nm of torque, this full-suspension fat-tire machine promises a confident, smooth, and natural ride—whether you’re commuting, trail blazing, or just exploring.
These models are positioned as the most powerful full-suspension mid-drive e-bikes under $3,500, combining premium components like a Shimano 10-speed drivetrain, hydraulic brakes, a long-range 48 V 19.6 Ah battery, and advanced display and comfort features—all at a compelling introductory price.
Features
Power & Handling
- Mid-drive motor (750 W rated, 1,300 W peak) with 210 Nm torque delivers vigorous power for climbing, descending, and mixed terrain. Its low center of gravity improves stability and control at higher speeds, minimizing fishtailing
- Intelligent torque sensor delivers smoother, pedal-matching assistance—far more natural than hub motors.
Drivetrain & Braking
- Shimano 10-speed drivetrain offers more gear range than typical 7- or 8-speed systems, optimizing high-speed cruising and low-gear climbing.
- Tektro HD-E3940 hydraulic brakes ensure strong, responsive stopping power—even on steep descents or wet surfaces.
Suspension & Comfort
- Full suspension system: dual-crown hydraulic fork (135 mm travel) plus DNM-38RC rear air shock (50 mm travel)—for nimble handling and long-ride comfort on rough terrain.
- 2-stage adjustable dropper seatpost and adjustable stem enhance fit, comfort, and handling across different riding styles and environments.
Display & Security
- Ultra-HD waterproof display (3.1-inch, 400×800 resolution) with anti-glare, rain resistance, and built-in digital lock adds convenience and security.
Battery & Range
- 48 V 19.6 Ah battery and smart energy management system offer 60–80 miles per charge—ideal for commuting or extended adventure rides—with 30% extended range from onboard intelligence.
Extra Safety & Utility
- Optional integrated rack with LED turn-signal taillight improves visibility and practicality at night.
Size & Fit
The Mokwheel Onyx is designed for a large frame that best suits taller riders. Here are its geometry specs:
- Recommended Rider Height: 5’7″ – 6’9″
- Reach: 19″
- Top Tube Length: 25″
- Stand-over Height: 31″
- Wheelbase: 50″
- Saddle Height Range: 35″ – 41″
- Head Tube Length: 6″
This geometry delivers a confident riding posture, ample leg extension, and stability—especially important for off-road and long-distance terrain.

Real-World Feedback & Testing
Because the Onyx is a brand-new release, independent ride reviews are still limited. However, Mokwheel’s earlier models—such as the Basalt and Obsidian—offer useful insight into what new owners might expect.
From Mokwheel’s own materials, the Onyx is promoted as having up to 80 miles of range per charge and being “perfect for off-road adventures,” aligning with the brand’s focus on capability and long-distance riding.
From rider communities, feedback on past Mokwheel bikes often highlights fun, powerful rides and reliable braking. At the same time, a few riders have noted frustrations with after-sales support. As one Basalt owner put it:
“The bike still works very well. It’s very fun to ride. The brakes are good quality. Customer service doesn’t exist.”
While this comment doesn’t reflect the Onyx specifically, it suggests a pattern: Mokwheel bikes tend to deliver strong performance and component quality, but prospective buyers should be aware that customer service may not be as polished as some premium competitors.
Independent third-party ride reviews are still emerging, so it’s worth keeping an eye out for updated testing impressions in the months ahead.
Who It’s For
- Riders seeking maximum power and torque in a mid-drive fat tire bike under $3.5k
- Adventure lovers tackling steep terrain, long commutes, or mixed conditions
- Those valuing a natural-feeling pedal assist and precise gear choice
- Beginners or daily commuters benefit from the Onyx ST’s step-through frame
- Riders who prefer premium suspension, display, and braking systems
Not ideal for riders seeking a lightweight, nimble urban cruiser or those concerned about post-purchase support.
Should You Buy the Mokwheel Onyx?
The Mokwheel Onyx Series—including both the standard Onyx and the step-through Onyx ST—positions itself as one of the most powerful full-suspension mid-drive fat-tire e-bikes under $3,500. At the current checkout price of $3,388.88 (regularly $4,088.88), it delivers an appealing package of premium components and high-performance engineering.
Why It Stands Out
- Mid-Drive Powerhouse: A 750 W motor (1,300 W peak) with 210 Nm torque makes hill climbs and off-road terrain feel effortless. The torque sensor ensures smooth, natural pedal assist without the jerky “push” of cheaper hub systems.
- Premium Ride Feel: Full suspension (135 mm fork, 50 mm rear shock) combined with 26″ × 4.0″ fat tires absorbs impacts and improves control on trails, gravel, or city streets.
- Drivetrain & Braking: Shimano 10-speed gearing and Tektro hydraulic brakes provide precision shifting and powerful stopping, giving riders confidence in varied conditions.
- Long-Range Battery: The 48 V 19.6 Ah battery supports 60–80 miles per charge, reducing range anxiety and making it fit for both commuting and long excursions.
- Smart Tech & Security: The 3.1″ ultra-HD waterproof display is sunlight-readable, integrates an electronic passcode lock, and pairs with optional accessories like turn-signal racks for added visibility and safety.
- Accessibility: With both a classic frame and a step-through ST option, Mokwheel broadens the appeal to adventure riders, commuters, and first-time e-bikers.
Considerations
- Weight: At about 89 lbs, it’s a heavy bike—harder to transport or lift compared to lighter commuter e-bikes.
- Customer Support: Past buyer feedback for Mokwheel suggests strong hardware but less-than-ideal after-sales support—worth factoring in for long-term ownership.
- New Release: Independent third-party testing for the Onyx is still limited; early impressions from Mokwheel’s other models point to strong performance, but more reviews will help confirm its claims.
Alternatives to the Mokwheel Onyx
Looking beyond the Onyx? Here are two distinctive e-bikes to consider, each excelling in different areas and budgets:
1. Heybike Alpha — Affordable Mid-Drive Fat-Tire Performer
- Motor & Performance: Equipped with a 500 W mid-drive motor (105 Nm) for smooth, natural pedal-assist that’s a big step up from typical hub motors.
- Components: Shimano 8-speed drivetrain paired with reliable hydraulic disc brakes.
- Battery & Range: Removable 680 Wh battery, tested ranges vary from 22 miles (high assist) to over 70 miles (low assist).
- Ride Features: Fat 26″ × 4.0″ tires, front suspension, integrated rear rack, fenders, lighting with turn signals, app support, and color display.
- Weight & Price: Around 71.6 lbs, and priced around $1,499.
Best For: Riders wanting a dependable mid-drive fat-tire e-bike experience on a budget—ideal for mixed commuting, trail riding, and casual adventures.

2. Specialized Turbo Levo Gen 4 — High-End Trail-Blazing Excellence
The latest iteration of Specialized’s flagship e-MTB series refines the electric mountain bike experience with top-tier power, range, and ride integration.
- Power & Motor: Specialized’s 3.1 motor delivers 101 Nm torque (up to 111 Nm in S-Works trim) and 666 W peak power, offering smooth but potent performance.
- Battery & Efficiency: Comes standard with an 840 Wh battery, offering long-range capability. Charging is impressively fast—in some models, up to 80% in under an hour.
- Suspension & Build: Trail-optimized with 160 mm front and 150 mm rear travel, supported by Specialized’s “Genie” shock system and premium chassis tuning.
- Weight: Despite robust build, tests place it around 52 lbs—light for its class.
- Price: Starts at around $7,999 for the Comp model, with higher trims (Expert, Pro, S-Works) well above.
- Ride Feel: Early impressions praise the refined delivery and “SuperNatural” power feel that amplifies the experience without overwhelming the rider.
Best For: Riders seeking the pinnacle of trail performance, with a brand that offers refined integration, dealer support, and unmatched ride quality—if budget isn’t a constraint.

Final Verdict
At $3,388.88, the Mokwheel Onyx delivers a blend of mid-drive torque, long-range battery, premium suspension, and smart features rarely found at this price point. It’s a top choice if you’re seeking an all-terrain, high-performance e-bike for under $3,500. Riders should be prepared for its heavier build and keep expectations realistic about post-purchase support—but in terms of specs and capability, it’s one of the best-value adventure e-bikes on the market.
