Step-through vs traditional eBike frame: which is better?

Step-through frames have a low or absent top tube, making mounting and dismounting easy — ideal for commuting in work clothes, riders with limited mobility, or stop-and-go city riding. Traditional (diamond) frames are stiffer and typically preferred for performance riding, trails, and higher speeds. For everyday urban commuting, step-through wins on convenience; for sporty riding, traditional frame wins.
