A 1300W rear-wheel drive fat tire bike is powerful due to its high-wattage brushless rear hub motor, robust battery system, efficient power controller, and the enhanced traction provided by wide fat tires. The motor delivers strong torque—up to 90 Nm—directly to the rear wheel, enabling rapid acceleration, sustained high speeds, and the ability to conquer steep inclines and rough terrain with ease.
How Does the 1300W Rear-Wheel Motor Generate Power?
The 1300W rear-wheel motor uses electromagnetic force to spin the rear hub, converting electrical energy from the battery into mechanical propulsion. Its brushless design reduces friction and heat, improving efficiency and durability. The motor operates on a 48V or 52V system, drawing up to 27 amps to deliver continuous power, which translates into speeds of 28 to 32 mph depending on conditions.
Chart: Motor Power, Torque, and Speed
| Motor Power (W) | Torque (Nm) | Top Speed (mph) |
|---|---|---|
| 750 | 60 | 20 |
| 1000 | 75 | 27 |
| 1300 | 85-90 | 28-32 |
Why Is Rear-Wheel Drive Effective for Fat Tire Bikes?
Rear-wheel drive applies power directly to the rear wheel, maximizing traction especially on loose or slippery surfaces like sand, snow, and mud. This direct drive reduces energy loss common in mid-drive systems that rely on chain and gear transmission. The rear placement also improves weight distribution, enhancing stability and control on challenging terrain.
How Do Fat Tires Complement the Motor’s Power?
Fat tires, typically 4 inches or wider, increase the contact patch with the ground, providing superior grip and shock absorption. This reduces wheel spin and helps the motor’s torque translate into forward motion rather than wasted energy. While fat tires increase rolling resistance by about 10-15%, the 1300W motor compensates by delivering extra power to maintain speed and acceleration.
What Battery Specifications Support a 1300W Motor?
A 48V 15Ah or 20Ah lithium-ion battery is ideal, storing 720 to 960 watt-hours of energy. This capacity supports sustained high current draw from the motor, enabling long rides of 45 to 65 miles depending on terrain and assist level. Advanced battery management systems (BMS) protect against overcharge, overheating, and extend battery life.
How Does the Controller Optimize Power Delivery?
The electronic controller regulates current flow from the battery to the motor, ensuring smooth acceleration and protecting components from overload. Controllers rated at 25-30 amps match the 1300W motor’s power demands, balancing performance with battery efficiency and thermal management.
What Maintenance Practices Keep the Motor Powerful?
Regular cleaning of the motor housing, inspection of electrical connections, and avoiding water immersion preserve motor efficiency. Maintaining proper tire pressure and drivetrain lubrication reduces strain on the motor, ensuring it delivers consistent power over time.
