If you’re looking for a full-size electric fat bike that blends massive power, long-range performance, and true all-terrain capability, the Mokwheel Obsidian 2.0 might be exactly what you’re after. I’ve reviewed a lot of electric fat bikes over the years, and the Obsidian 2.0 immediately stands out because it doesn’t try to be compact or lightweight—it’s designed to be strong, stable, full-suspension, and confidence-building on rough terrain.
Today, I’m breaking down everything you need to know from real test-ride experience and deep research: how the Obsidian rides, how powerful it really feels, how the suspension performs on rough ground, size and fit, pricing, and what you should consider before buying. This is built for riders who want capability and comfort without compromise.

This e-bike is built to handle tough terrain—gravel, sand, forest paths, fire roads—and still keep the rider extremely comfortable.
Motor and Power Delivery
The Obsidian’s motor is one of the strongest in its class, delivering 1300W of peak power and over 105 Nm of torque. That torque is what really makes the difference. You can feel it when you tackle a steep incline or accelerate from a stop with gear loaded onto the back.
With both torque and cadence sensors working together, the motor reacts instantly when you push on the pedals. There’s a noticeable power surge when taking off, but it feels controlled and natural when you’re climbing hills or picking up speed.
If you’re on loose terrain, the torque sensor keeps traction steady without spinning out, and the cadence sensor adds extra boost when your pedaling cadence slows.
Speed and Ride Feel
Pedal assist allows speeds up to 28 mph, and the stability of the bike makes those higher speeds feel secure. The 26×4 fat tires add a lot of confidence—especially on loose or uneven surfaces. Don’t expect super tight turns given the big tires, but the frame geometry keeps the bike balanced.
With the thumb throttle, you’ll quickly reach 20 mph, which is awesome when you need a burst of speed.
Suspension and Comfort
This is where the Obsidian truly separates itself from other fat-tire e-bikes in its price range. The Obsidian 2.0 isn’t just a front-suspension bike—it offers a legitimate full-suspension system with several comfort features working together.
Here’s what that means for real-world riding:
130mm Adjustable Front Suspension Fork
This fork absorbs the big hits—potholes, roots, rocky descents, loose gravel. Being adjustable means you can dial it in based on your weight and riding style. If you’re tackling rough terrain, open it up. If you’re riding on pavement, tighten it for a more efficient feel.
Pro 50mm Mid-Mounted Air Shock (Rear Suspension)
This is the feature that dramatically improves comfort. An air shock is more tunable than a coil shock, and it helps the rear wheel track the ground instead of bouncing you around. On rocky trails or uneven fire roads, the rear shock smooths out impacts and reduces fatigue, making long rides much more enjoyable.
The benefit here is simple: you stay in control, the bike maintains traction, and you don’t feel beat up after an hour on rough dirt. You can see how the suspension absorbs impact here… and I honestly felt like I was riding on air.
Adjustable Hydraulic Seatpost
With a quick tap, you can raise or lower the seat height. This matters more than people realize—lower it at stops for stability, raise it on the trail for proper pedaling mechanics. It adds both comfort and safety, especially if you ride in varied terrain.
Cushy Saddle
The saddle is soft, broad enough for stability, and shock-absorbing enough for long rides. Combined with the rear air shock, the cushion helps eliminate the harsh vibrations that normally travel up through your hips and lower back.
Ergonomic Grips
The grips are soft, supportive, and easy to hold even over long distances. During testing, they felt gentle on the palms and prevented hand fatigue, especially when riding over rough ground where vibration is usually an issue.
Together, these suspension and comfort features created one of the smoothest rides I’ve had on a fat-tire e-bike. This is a bike built for riders who want to handle rough trails—but still want to feel comfortable while doing it.
Braking and Control
The TEKTRO hydraulic disc brakes provide excellent stopping power and are well-matched to the weight and speed of the bike. On steep downhills or when riding on slippery terrain, the brakes feel responsive and predictable. You get strong deceleration without the spongy feel of mechanical brakes.
Range and Battery
With a 48V 19.6Ah UL-certified battery, the Obsidian offers a range of 60 to 80 miles depending on how aggressively you use pedal assist and throttle. That’s a large battery for a bike of this type, and the efficiency of the motor system helps stretch your miles even further.
The included 3-amp charger reduces charging time compared to the slower 2-amp chargers most other brands offer.
Build Quality and Design
The Obsidian uses a 6061 aluminum alloy frame with an internally mounted battery. The internal routing keeps things clean and protects wiring from weather and debris.
Heavy-duty spokes, aluminum alloy rims, and a staggering 560-pound payload capacity make this bike extremely capable for riders carrying heavy loads. This is one of the strongest payload ratings in the entire e-bike category.
The detachable HD display is fairly easy to read in sunlight and turns the power off when removed, and gives you security.
The Shimano 10-speed drivetrain adds flexibility that most e-bikes in this price range don’t offer. It gives you finer control when climbing and better efficiency on flat ground. Plus, it helps you greatly extend range by lowering the electric assist needed.
Size and Fit: Who This Bike Works For
The Mokwheel Obsidian 2.0 comes in a step over or step-through frame as shown in this review. The step-over best fits riders from 5’6″ to 6’8″, whereas the step-through is best for 5’2” to 6’4”.
- Standover height: 20 inches
- Minimum saddle height: 35 inches
- Maximum saddle height: 41 inches
Shorter riders may find even the step-through frame tall or the reach far, especially if you’re closer to 5’1 like myself. Taller riders will find either frame comfortable and surprisingly roomy. The full-suspension frame, wide tires, and large wheelbase make it feel like a full-size mountain or adventure bike—not a compact commuter.
The hydraulic seatpost does help with adjustability and confidence at stops.
Assembly and Ease of Use
The bike comes pre-assembled. You’ll attach the front wheel, fenders, handlebar, pedals, and a few small components. Make sure to watch the Mokwheel assembly video.
Because it weighs 77 pounds, it’s important to understand that this is not a lightweight or portable bike. Transporting it requires strength or a proper e-bike-rated vehicle rack. But once you’re riding, the weight contributes to the stability.
What You Need to Know Before You Buy
Here are the key takeaways from testing and reviewing:
Power: This is one of the more powerful fat-tire e-bikes on the market, delivering climbing ability and acceleration that outperform many bikes in its class.
Comfort: The full-suspension system, air shock, ergonomic grips, and cushy saddle make rough terrain surprisingly comfortable.
Size: Although I was able to fit on the bike at 5’1”, it’s best suited for taller riders. Smaller riders should check their fit carefully.
Weight: At 77 lbs, it’s heavy. This is not a bike you’re lifting easily, so consider your storage and transport situation.
Terrain: Excellent on rough terrain or pavement. The suspension system makes it suitable for genuine off-road use.
Payload: The 560-pound payload capacity makes it highly capable for heavy riders and heavy loads.
Warranty: Mokwheel offers a two year limited warranty. Check their current terms online for the most accurate details.
Pricing and Value
If you want an all-terrain e-bike that rides like a high-end adventure machine—but without the premium price tag—the Obsidian 2.0 delivers.
For a full-suspension fat-tire e-bike with this much power, range, and comfort, the just over $2000 price is competitive. Many bikes offering similar specs cost significantly more. The combination of the air shock, torque sensor, large battery, and 10-speed drivetrain puts the Obsidian 2.0 in a strong value category. And, you can even add solar power accessories to harvest your own energy.

Final Thoughts: Should You Buy It?
If you want a powerful, full-size, full-suspension electric fat bike designed for serious off-road use, the Mokwheel Obsidian 2.0 is absolutely worth considering. It offers a smooth ride thanks to its air shock and adjustable fork, excellent torque for climbing, and a long-range battery that keeps you out on the trail longer.
It’s not lightweight and it’s not ideal for shorter riders. But larger riders who want both power and comfort, it’s a strong contender.
