How Fast Can a 5000W Ebike Convert to MPH?
How Does Motor Efficiency Affect Speed Conversion?
Mid-drive motors achieve 85-90% efficiency, translating 5000W input to ~4250-4500W output. Hub motors operate at 75-85%, losing 750-1250W as heat. For example, a 5000W hub motor at 80% efficiency delivers 4000W—reducing top speed
