Bafang M430 Drive System: 300kg Professional Cargo Bike Product
Bafang is launching the M430 drive system, a professional-grade solution for cargo bikes with a 300kg load capacity.
Introduction
With the increasing demand for urban logistics driven by online consumption, Electric Cargo Bikes are emerging as a flexible and low-carbon transportation solution, becoming a common sight in cities.
At Eurobike 2025, Bafang will unveil the M430 drive system, specifically designed for professional cargo bikes with a total load capacity of 300kg. This system boasts a maximum torque of 120Nm, a peak power output of 910W, and a maximum assistance ratio of 800%.
According to Wang Yingzhe, Bafang's Senior R&D Manager, "The parameters for this system are not arbitrary; they are the result of 17 years of experience. Since Bafang's collaboration with the French Post Office on their postal vehicle project in 2008, we have undertaken numerous commercial and sharing projects, deeply understanding the demands of such applications."
A cargo bike, by definition, requires a vehicle capable of handling heavy loads and frequent starts and stops, with high road compatibility. It needs to provide effortless starting, acceleration, and climbing, even with prolonged loads, offering agile response and flexible operation. These are the product characteristics that riders expect. In technical terms, this translates to the need for high torque, high power, and a higher assistance ratio.
Understanding Key Specifications
Torque
Torque refers to the 'strength' of the motor. It directly impacts starting and acceleration capabilities, climbing ability, load-carrying capacity, and low-speed power response. Simply put, a motor with high torque is like a very strong person; even at low speeds or during climbs, it can exert significant force to propel you forward.
Power
Power indicates the amount of energy a motor can output per unit of time. It affects the ability to maintain speed, maximum assisted speed, and overall power output. In essence, a motor with higher power is like a person who can run very fast and sustain high speeds.
Assistance Ratio
The assistance ratio is the amplification factor of the motor's output torque relative to the rider's pedaling torque. It directly influences climbing ability and the ease of starting and acceleration. A higher assistance ratio means the motor contributes more to the drive, compensating for the resistance caused by extra weight. This significantly reduces the rider's physical exertion, making long rides less tiring and rides on uneven surfaces more manageable.
M430 System Features
The M430 system is designed to meet the demands of professional cargo bikes. Its high-precision torque sensor ensures seamless integration between pedaling force and motor output, significantly improving responsiveness during starts and acceleration while reducing pedaling effort. The system feels as if your own strength is amplified.
The system offers different power and assistance levels across various modes, allowing users to switch riding modes based on the cargo load. For instance, riders can select 'Sport' mode for enhanced assistance when carrying heavy loads, and switch to 'Eco' mode when unloaded to extend battery life and improve overall travel efficiency.
For extended use with heavy loads, effective thermal management is crucial. The M430 system incorporates new heat dissipation technology, reducing temperature rise by approximately 10%. Combined with efficient control algorithms, this technology broadens the efficiency platform and increases overall efficiency by about 5%, further reinforcing the product's durability and reliability.
Conclusion
Ultimately, while specifications are important tools, user needs are paramount. Bafang develops and refines its product lines based on diverse application requirements to support your journeys.
