The SAMEBIKE M20-III 2000 W – dual-motor electric fat bike is a robust dual-motor electric fat bike for the rider who wants an exceptional amount of power, traction and range from their electric bike.
This electric mountain bike combines two motors, two batteries, wide fat bike tires, and a motorcycle-like riding position.
The M20-III doesn't try to look like a regular city bike. The long seat, strong frame, and aggressive styling immediately tell you that this is a powerful e-bike designed for long rides and varied terrain.
🔥 Two motors – total 2000 W
The SAMEBIKE M20-III electric fat bike has two 1000W motors, providing a total rated power of 2000W. The dual-motor design improves acceleration, traction and traction, especially on uphill, soft ground and uneven trails.
According to the manufacturer, the motors produce a total torque of over 160 Nm. The power is distributed between the front and rear wheels, which helps the e-bike move steadily on gravel, sand, snow and more challenging terrain.
🔋 Two batteries and a very long range
The M20-III has two 48 V 18 Ah batteries, with a combined capacity of 48 V 36 Ah or 1,728 Wh. The large battery capacity reduces the need for constant charging and makes the electric fat bike suitable for long day trips.
The manufacturer states that the range is approximately 140–280 kilometers, depending on the riding and assistance mode. When both batteries are in use, the bike automatically uses them together. The actual range depends on factors such as the rider's weight, temperature, terrain, tire pressure, riding speed, and the assistance level used.
🌲 Wide-tire electric bike for off-road and city use
The M20-III is equipped with 20×4,0-inch puncture-resistant fat bike tires. The wide tire increases contact patch, improves stability, and helps maintain traction on varying riding surfaces.
This powerful electric mountain bike is suitable for:
- for asphalt and cycle paths
- for gravel roads and forest trails
- for sand and soft surfaces
- for snowy and slippery roads
- for longer leisure trips
- for commuting and camping use
Wide tires and a dual-motor drive system make the M20-III more stable even when the grip of a regular e-bike starts to weaken.
🛞 Full suspension smooths out uneven trails
The SAMEBIKE M20-III has adjustable and lockable front suspension and a powerful rear suspension shock absorber. The full suspension reduces shocks and vibrations to the rider on bumpy roads and uneven terrain.
The long motorcycle-style saddle offers a wider seating area than a standard bicycle saddle. Combined with the suspension, it makes the riding position comfortable even on longer journeys.
🛑 Hydraulic disc brakes
A powerful and heavy electric fat bike needs brakes you can trust. The M20-III is equipped with hydraulic disc brakes front and rear.
The hydraulic braking system provides a smooth, responsive and easily dosed braking feel. The brakes support controlled stopping in city traffic, on steep descents and in variable weather conditions.
⚙️ Shimano 7-speed transmission
The Shimano 7-speed transmission allows you to select the right gear for your riding speed, terrain and assistance level. A lighter gear makes it easier to pedal uphill, while a larger gear is suitable for faster road sections.
The gearbox allows you to combine electric assistance and traditional pedaling depending on the situation.
👍 Thumb throttle for effortless progress
The SAMEBIKE M20-III has a thumb throttle. The throttle allows you to control the motor assistance directly from the handlebars without having to continuously pedal.
The thumb throttle makes it easier, for example, to start off, climb steep hills, and in situations where the rider wants to take a break from pedaling. The factory-set speed stated by the manufacturer is 25 km/h.
📱 Large 4,2-inch color display
The 4,2-inch color LCD display located in the center of the handlebars displays key driving information clearly in the driver's field of vision.
The screen can display, among other things:
- driving speed
- distance traveled
- battery charge level
- selected gear
- brake condition
- walking allowance
- headlight operation
The ergonomically designed handlebar supports a stable riding position and makes it easier to use the controls.
💡 Powerful lights and brake light
The bright LED front light improves visibility in low light and darkness. The red light at the rear also acts as a brake light: it reacts to the brake lever and warns traffic behind you to slow down.
The lights make this wide-wheeled electric bike practical for commuting and longer evening rides.
