Dual motor electric bikes are all the hype, offering unmatched power and off-road strength. But twice the motors doesn’t always mean twice the performance. This is a deep dive into the world of full-suspension dual motor fat tire e-bikes with a focus on what they’re really good at, their compromises out on the trail, and whether perhaps you’d be better off with a high-end single-motor option in your own adventures so that you can actually make an educated decision outside of the marketing hype.
1. Performance Deep Dive: The Unrivaled Power and Traction of Dual Motors
To begin with, the main draw of a dual motor e-bike is its raw performance, and that translates into a noticeable impact when it comes to traversing tricky terrain. By putting a motor in the hub of both the front and rear wheel, these bikes become a true all-wheel-drive (AWD) system. This changes how they interact with the ground. But this isn't just about speed; it's about keeping a firm grip and applying torque where single-motor machines might struggle. Knowing these particular benefits is critical for deciding if you need this kind of power.
Better All-Around Tread
The biggest advantage is the noticeably improved traction. It can also spin-out less frequently on loose or slippery terrain, since two independent motors drive each wheel.
Sand and Snow
Because the front wheel pulls while the rear wheel pushes, the tire "floats" over soft dirt or sand instead of digging in and getting stuck.
Mud & Wet Leaves
During wet or muddy conditions, the AWD system responds instantly to provide added traction to both wheels when one slips, causing less tire wear and better performance on slick surfaces.
Effortless Hill-Climbing Feats
Uphill rides are tough on a single motor. This workload is split between two motors, and uphill performance becomes impressive.
Less Motor Strain
Each motor is working less hard, which can provide better thermal performance and a potentially longer lifespan for the motors during high-demand use.
Steady Speed
The bike is able to achieve and maintain a better pace and steady speed while going up hills, especially steep hills.
Explosive Acceleration
With power being supplied from two sources, one on each wheel, initial acceleration from a standstill is noticeably faster. This can be a big leg up in stop-and-go city traffic or when crawling over an obstacle on the trail.
Rider Control and Flexibility
When compared to single motors, dual motor e-bike systems allow for selectable riding modes, giving you ultimate freedom in how the power is delivered. This is one key feature to consider.
Rear-Motor Mode
It is recommended for normal riding conditions in order to save battery.
Front-Motor Mode
Useful in some low-traction situations for pulling the bike around a corner.
Dual-Motor (AWD) Mode
Delivers full power for maximum acceleration and for the most challenging terrain.
2. The Stronger Replacement: Why a Skilled Single-Motor Winner Can Succeed
While dual motors provide a ton of power, one has to wonder: is all that complexity really required? Simply put, for many riders, a well-made single-motor fat tire electric bike offers a better, safer, and ultimately more fun riding experience. The ENGWE M20 is the epitome of this philosophy. It's a testament to how intelligent design, better components, and focusing on the whole rider package are often more important than just lobbing a second motor at it. Instead of simply adding a more powerful motor, ENGWE concentrated on real-world performance that improves control and long-term durability.
Compact and Powerful Motor
In addition to its powerful battery, the ENGWE M20 provides excellent performance using a brushless motor that has up to 55 N.m of torque. That’s plenty of power for steep city climbs and aggressive trails, offering powerful acceleration and reliable performance without the weight or complexity a second motor creates.
Exceptional Comfort and Control Through Dual Suspension
The M20 is where everything gets excellent and offers a real alternative. Uncontrolled power is useless. With the M20's sophisticated dual suspension, which includes a front hydraulic shock and rear air shock absorber, you get double the damping. It will keep those fat tires glued to the planet for unparalleled traction and control, delivering a level of comfort and stability on rough sections of trail that many solid-frame dual-motor bikes simply cannot compete with.
Getting Rid of Range Anxiety
A dual motor electric system is notorious for draining a lot of energy. The issue of range is critical, and this is something the ENGWE M20 addresses with its optional dual-battery setup. The 26Ah gives up to a crazy maximum range of 75km + 75km. A summer day adventure checklist item; space in the van for days-long, relocated adventures… one goal that is very much achievable now!

3. The Natural Trade-offs: Cost, Weight, and Complexity
Choosing to go for a dual motor electric bike isn’t just about making performance gains; it’s also about settling for a whole bunch of trade-offs. Duplicating your powertrain affects everything—from your pocketbook to your daily use and physically handling the bike. It’s important to consider these cons against the performance advantages to determine if they are a good fit for your individual use cases and lifestyle before you make that investment.
Much Higher Cost of Purchase
This is typically the greatest barrier to entry. You’re not just buying an extra motor.
Duplicated Components
A second motor means a second dedicated controller.
More Wiring
The power and data wiring is a bit more complicated since two controllers, the battery, and the display need to be wired together.
Bigger Battery Needed
They will need big ones if they are to go any kind of distance while pushing two motors, and those are expensive.
Additional Weight
The heaviest components on an e-bike are the motor and controller. And a second set, of course, brings double the weight, added directly to the bike.
Limited Portability
It's a lot more challenging to lift a heavier bike onto a car rack, take it up stairs, or maneuver it in tight spaces.
Handling Dynamics
The additional weight, particularly in the front hub, can cause a noticeable increase in steering effort and may feel less nimble than a single rear-hub motor setup.
Larger Maintenance and Repair Scope
More moving parts and greater use of electronics mean that there are simply more things that can break.
Troubleshooting
Finding problems can be more complex. Which is at fault: the front motor, rear motor, front controller, rear controller, or some wiring connecting them?
Finding a Trained Technician
Not every bike shop is going to have the ability or knowledge to perform service on a dual motor system like this.
Reduced Range
This is a significant factor many of us may have overlooked. Even with a higher capacity battery, a dual motor bike will almost always have less range than a single motor bike when both are ridden in the same conditions. Simply moving the bike with two motors requires more power, and that means charging sooner.
4. Use Case Scenarios: Who Needs a Dual Motor E-bike?
The answer to the question, “Are dual motor electric bikes better?” is itself a question: “Better for what?” The perfect e-bike is the one that perfectly aligns with its rider’s particular needs and preferred terrain. An all-wheel-drive system is a specialty tool; like any other such device, it’s good in some settings and overkill in others. Knowing your specific use case is the best way to know if you qualify for an AWD system or if one powerful single motor on a small, lightweight bike will do.
Here is a breakdown of rider profiles and their appropriate motor setups!

Frequently Asked Questions
Q1: Does using dual motors on an electric bicycle reduce its range?
Yes, generally they do. Two motors will always draw more juice from the battery when running together than one. So while the bike may have a very large battery, its range will likely be less than that of a single-motor bike with the same size battery ridden in the same conditions on dual mode.
Q2: Are dual motor e-bikes more difficult to maintain?
They can be. That’s because with two motors, two controllers, and more elaborate wiring, there are just more parts that can potentially fail. It’s also more complicated to troubleshoot a problem, and finding a mechanic with specialized experience working on these advanced AWD systems can be more difficult than finding service for a standard e-bike.
Q3: Is a powerful single-motor e-bike a better option for most people?
For the vast majority of cyclists, the answer is yes. A good single-motor fat tire e-bike will provide a great mix of power, efficiency, lower weight, and lower cost. There's ample power for daily commuting, trail riding, and fun in general, without the compromises of a dual-motor bike.
Ultimately, the best electric bike for you is one that works well with your own personal riding adventures.
