Electric bicycle powertrains are a core component of electric vehicle technology, and in recent years this field has experienced significant technological advances and innovations:

1. Dual Powertrain design: Canadian manufacturer Biktrix has upgraded its Juggernaut XD electric bike with an innovative dual powertrain design. Retaining the traditional pedal power on 

the right side and a high-power motor on the left, this design greatly improves the performance and flexibility of the vehicle, allowing riders to freely switch power sources in different road 

conditions, enjoy a longer range (up to 64km) and a better riding experience.

2. Efficient power system design: The article mentions that China, as the world's largest electric bicycle market, dominates the market share, but many electric bicycles still use older sealed 

lead acid (SLA) battery technology. As technology advances,

More and more small and efficient power subsystem designs for electric bicycles are starting to appear on the market, which are designed to improve battery performance, reduce weight, 

extend range, and improve overall energy efficiency.

3. Valeo's new electric bicycle powertrain: Valeo, an internationally renowned auto parts supplier, has launched a new powertrain specifically for electric bicycles. This system not only improves 

the performance of the e-bike, but may also include intelligent auxiliary functions such as adaptive power distribution to optimize energy consumption and enhance the riding experience. Such 

innovations are of great significance in pushing the e-bike industry towards higher technical standards.

4. Brushless DC motor control system: Research on the brushless DC motor control system for electric bicycles is also continuing to deepen. These systems use precise electronic commutation 

control to achieve efficient motor operation, improve power output smoothness and response speed. With the optimization of control algorithms and the improvement of sensor technology, 

the drive system of electric bicycles can better adapt to different riding environments and user needs.

5. Graduation design project of electric bicycle drive control system: Some academic research and graduation design projects focus on the drive control system of electric bicycles, exploring how 

to optimize the motor control strategy through advanced microprocessors and intelligent algorithms to achieve more accuracy

Power assisted control and energy efficiency management. These studies help to improve the intelligent level of electric bicycles and make riding more comfortable, safe and environmentally friendly.

In summary, the technical development trend of electric bicycle power system includes but is not limited to the design of dual power system, the application of efficient battery technology, the 

development of intelligent control system and the optimization of brushless DC motor control. These technological advances have not only been enhanced

The performance and endurance of electric bicycles also provide users with a richer and more diverse riding experience.
