Meet the PHILIAM F3 PRO: A Powerful Dual Motor Fat Tire E-Bike

PHILIAM F3 PRO: A Dual Motor Electric Bike Built for Hills, Trails & Everyday Riding

Choosing an electric bike is no longer just about finding enough power for a daily commute.

More riders are looking for one bike that can handle city streets during the week, hills and rough roads on the weekend, and longer rides without constantly worrying about battery range.

That is where a dual motor electric bike starts to make sense.

Instead of relying on a single drive motor, a dual motor e-bike can deliver power through both the front and rear wheels. This provides additional performance when accelerating, climbing hills, or riding across demanding terrain.

The PHILIAM F3 PRO is designed around this combination of power and versatility.

With dual 1500W motors, up to 4000W peak output, a 52V 23Ah removable battery, 26×4-inch fat tires, hydraulic disc brakes, and a suspension system, the F3 PRO is built for adult riders who want more than a basic commuter e-bike.

Why Choose a Dual Motor Electric Bike?

Most conventional e-bikes use a single motor located at the front wheel, rear wheel, or crank.

A dual motor electric bike adds another source of drive.

On the F3 PRO, the system uses:

1500W front motor + 1500W rear motor

with up to 4000W peak output.

This configuration is particularly useful when the ride becomes more demanding.

On flat pavement, you may not always need maximum power. But when the road gets steeper, the surface becomes loose, or stronger acceleration is needed, having two motors gives the bike additional performance in reserve.

That makes dual motor e-bikes particularly appealing to riders dealing with hills, trails, gravel roads, and mixed terrain.

Dual 1500W Motors with Up to 4000W Peak Power

Power is one of the defining features of the F3 PRO.

The bike uses dual 1500W brushless motors with a listed peak output of up to 4000W and torque of up to 160 Nm.

Rather than viewing those numbers only in terms of top speed, it is more useful to think about where additional motor performance matters.

Climbing Hills

Inclines place much greater demand on an electric bike than flat roads.

A dual motor system gives the bike additional drive when climbing, making the F3 PRO suitable for riders who regularly encounter hilly routes.

Faster Acceleration

Two motors can provide stronger acceleration when more power is requested.

This can be particularly noticeable when starting on an incline or accelerating with a heavier rider.

Demanding Terrain

Loose gravel, dirt roads, and uneven surfaces can require more from an e-bike than ordinary pavement.

Having power available at both wheels can provide additional traction and drive in situations where a conventional single-motor bike may have to work harder.

For riders specifically searching for an electric bike for hills and trails, motor configuration is therefore worth considering alongside battery capacity, tires, brakes, and suspension.

52V 23Ah Removable Battery for Longer Rides

Motor power is only half of the equation.

A powerful electric bike also needs sufficient battery capacity.

The F3 PRO uses a 52V 23Ah removable lithium-ion battery. PHILIAM currently lists a riding range of up to 80 miles with pedal assist or approximately 35 miles using pure electric power, depending on riding conditions.

Actual range can vary based on factors including:

• Rider weight
• Terrain
• Hills
• Speed
• Motor usage
• Pedal-assist level
• Tire pressure
• Temperature
• Wind
• Stop-and-go riding

This distinction matters particularly with a dual motor e-bike.

Using maximum power from both motors continuously will generally consume more battery energy than riding at moderate speeds with pedal assistance.

The removable battery also makes charging more convenient because riders can remove it from the bike when appropriate rather than always moving the entire bike to a power outlet.

26×4 Fat Tires for All-Terrain Riding

The F3 PRO uses 26×4-inch fat tires.

Fat tires have become popular on all-terrain electric bikes because their larger contact patch and volume can provide additional traction and cushioning compared with narrower tires.

They are particularly useful when riding across surfaces such as:

Gravel, dirt, grass, sand, snow, rough pavement and uneven trails.

This does not mean every fat tire e-bike is automatically suited to every off-road environment. Motor power, frame design, brakes, suspension, rider skill, and tire pressure all matter.

But when paired with a dual motor system, fat tires help make the F3 PRO a much more versatile platform than a conventional narrow-tire commuter bike.

This combination is one reason searches such as dual motor fat tire electric bike and fat tire electric bike for adults are especially relevant to this model.

Suspension for Rough Roads and Trails

Motor power gets most of the attention on high-performance electric bikes, but comfort and control are just as important.

The F3 PRO includes an oil-spring front suspension fork, helping absorb impacts from uneven surfaces.

Suspension becomes increasingly useful when riding over:

Potholes, cracked pavement, gravel, dirt roads, bumps and uneven trails.

Combined with the 26×4-inch fat tires, this helps the F3 PRO transition between everyday roads and more demanding riding conditions.

For buyers comparing all-terrain e-bikes, this is an important reminder that motor wattage should never be the only specification you evaluate.

Hydraulic Disc Brakes for Confident Control

More performance also makes braking capability increasingly important.

The F3 PRO uses front and rear hydraulic disc brakes, designed to provide responsive braking and predictable control.

Hydraulic braking systems can provide strong braking force with relatively controlled lever input, which is particularly valuable on heavier, faster electric bikes.

This matters when descending hills, navigating changing terrain, or carrying additional load.

When shopping for a powerful dual motor electric bike, brakes should therefore be considered alongside motor output rather than treated as an afterthought.

Torque Sensor for More Natural Pedal Assist

One feature that can get overlooked on a spec sheet is the F3 PRO's torque sensor.

A torque sensor responds to how much force the rider applies to the pedals.

Instead of simply detecting whether the pedals are turning, the system can adjust assistance based on rider effort.

The result can feel more natural during normal pedal-assisted riding.

This is particularly useful because the F3 PRO is not designed only around maximum motor output. Riders can use pedal assistance for longer-distance riding and reserve stronger motor performance for situations where it is actually needed.

7-Speed Drivetrain and Multiple Assist Levels

The F3 PRO combines electric assistance with a 7-speed chain drive system and multiple electric assist levels.

That gives riders more control over how they use the bike.

Lower gearing can help when climbing, while higher gears are useful for maintaining speed on flatter sections.

Combined with adjustable pedal assistance, this gives riders more flexibility to balance:

Power → Range → Pedaling effort → Terrain

That flexibility is valuable on a long ride where conditions may change several times.

Built for Adult Riders

Fit and load capacity are important when shopping for an electric bike for adults.

PHILIAM currently recommends the F3 PRO for riders approximately 5'4" to 6'5", with a maximum load capacity of 400 lb.

This gives the bike a relatively broad fit range.

However, rider height alone should not determine whether an e-bike is suitable. Riding position, reach, inseam, intended terrain, and personal comfort should also be considered.

How Fast Is the PHILIAM F3 PRO?

The F3 PRO is currently listed with a maximum speed of up to 37 MPH, depending on configuration and applicable settings.

That places it well beyond the performance of many conventional commuter-oriented e-bikes.

However, riders should always check local regulations before using higher power or speed settings on public roads, bike paths, or trails.

Electric bike classifications and permitted motor output or assisted speeds vary by jurisdiction.

The fact that a bike is technically capable of a certain speed does not mean that speed is permitted everywhere.

Who Is the F3 PRO Designed For?

The F3 PRO makes the most sense for riders who want versatility rather than an e-bike built around only one type of riding.

It may be worth considering if your routes regularly include:

Steep hills — dual motors provide additional climbing performance when needed.

Gravel and trails — fat tires and suspension help the bike handle changing surfaces.

Longer rides — the 52V 23Ah battery provides additional capacity for extended trips.

Mixed terrain — the combination of fat tires, suspension, dual motors, and hydraulic brakes is designed for more than smooth pavement.

Heavier loads — the bike is rated for up to 400 lb.

For someone riding almost exclusively on flat paved roads at moderate speeds, a lighter single-motor commuter bike may also be worth considering.

The value of a dual motor system is greatest when your normal riding actually benefits from the additional power and traction.

What to Look for When Buying a Dual Motor Electric Bike

Do not choose a dual motor electric bike based on motor wattage alone.

A better approach is to evaluate the complete system.

Start with the battery. Two powerful motors need enough stored energy to provide useful riding range.

Then consider the brakes. More speed and weight make reliable braking increasingly important.

Next are the tires and suspension, particularly if you plan to leave smooth pavement.

Finally, consider fit, weight capacity, charging time, certification, drivetrain, replacement parts, warranty, and after-sales support.

The F3 PRO combines these elements into one platform: dual 1500W motors, a 52V 23Ah removable battery, 26×4 fat tires, hydraulic disc brakes, suspension, torque-sensing pedal assist, and a 400 lb load rating.
