How Does the LvBu KN Kit’s Electric Assist System Work?

The LvBu KN electric assist system is a high-tech setup integrating a motor, battery, controller, and smart algorithms, designed to provide stable and personalized power support for cyclists.

1. System Components
Motor: The LvBu KN uses a high-speed brushless permanent magnet motor, known for being lightweight, compact, and free from magnetic resistance. This allows for easy pedaling even when the battery is depleted. The motor comes in two power options: 250W and 350W, delivering ample power for the rider.
Battery: The system features a 20-cell 18650 lithium-ion battery, offering high energy density and long lifespan. It provides a range of up to 60 km on assist mode. The battery includes a built-in BMS protection system to ensure safety, stability, and water resistance.

2. Operating Principle
Data Collection: During riding, the controller collects various data from built-in sensors, such as speed, acceleration, and angular velocity.
Smart Analysis: The collected data is processed by the main chip in the controller, which uses smart algorithms to analyze and assess the rider's riding status.
Power Output: Based on the analysis, the controller manages the motor’s power output. When the rider needs assistance (e.g., climbing or accelerating), the motor activates to provide support. Conversely, on flat or downhill terrain, the motor may reduce or stop power output to conserve battery.
Mode Switching: The LvBu offers various assist modes, including commuting, exercise, leisure, climbing, and manual. Riders can switch between modes via the mobile app or Bluetooth bike computer, catering to different riding needs.

3. Advantages and Features

Smart and Convenient: The system adjusts power output based on the rider’s needs and riding conditions, making cycling easier and more convenient.
Easy Installation: With the complete battery, motor, and control solutions provided, no need to select parts separately—upgrade is quick and simple.
Safe and Reliable: The BMS protection system ensures battery safety and stability. Additionally, the IP65 water resistance rating allows for worry-free short rides in various weather conditions.
Versatile Compatibility: The LvBu KN supports various wheel sizes from 12" to 29" and is compatible with most bike models, offering more choices and convenience for riders.

In summary, the LvBu KN’s electric assist system combines advanced motor, battery, controller, and smart algorithms to precisely sense and respond to rider power needs, delivering a more convenient, efficient, and safe cycling experience.
