how to choose ebike

The bicycle market has become more diverse with the rise of e-bike technology, featuring a range of models from a few thousand to tens of thousands of dollars, attracting widespread attention. However, many people may have misconceptions about e-bikes and electric motor systems when making their selection. This article will analyze various aspects such as overall geometry design, power, torque, pedal frequency, and battery capacity, providing you with insights for making informed decisions when purchasing an e-bike.

Overall Geometry Design: New Trends in Electric Bicycle Geometry

Choosing an e-bike requires attention not only to technical performance but also to the overall geometry design. Taking long-travel full-suspension e-mountain bikes as an example, recent design trends lean towards longer Reach, smaller head tube angles, and innovative features such as the Mullet mixed-wheel setup with a larger front wheel (29 inches) and a smaller rear wheel (27.5 inches). Innovations like high pivot suspension systems and chain tensioning wheel designs contribute to a more flexible and stable riding experience.

Motor System Performance: Balancing Power, Torque, and Pedal Frequency

When selecting an e-bike, it is crucial to consider power, torque, and pedal frequency. Power is the core parameter of motor performance, including rated power and peak power. Peak power represents the maximum power output when there is a sudden or short-term increase in load demand, while rated power signifies the motor's stable operational capability. Additionally, torque, which refers to the rotational force generated by the motor, plays a significant role in providing robust power, especially during uphill climbs.

Simultaneously, paying attention to pedal frequency is essential. E-bike systems rely on torque sensors and internal algorithms to adjust motor output in real-time. Maintaining a steady pedal frequency within a reasonable range enhances motor efficiency, resulting in a more powerful assistance. A high-quality e-bike system should maintain robust power output across the entire pedal frequency range and exhibit quick motor response.

Key to Endurance: Choosing the Right Battery Capacity

Battery capacity is a crucial factor affecting the endurance of an e-bike. Two common ways of representing battery capacity include Ah (ampere-hours) at the rated voltage and Wh (watt-hours) as a measure of energy. A larger battery capacity implies a longer range, but it also comes with increased overall bike weight. In real-world scenarios, some models use external battery packs to supplement endurance, providing riders with more options.
