When selecting an Electric Two Wheeler (E2W), you must prioritize the Battery Type, typically choosing between Lithium-ion (LiFePO4 or NCM) for longevity and energy density or Lead-acid for cost-sensitive markets. The Motor Power (measured in Watts) determines climbing ability and top speed; for urban commuting, 1000W to 3000W brushless DC (BLDC) motors are standard. Additionally, verify the Controller efficiency and the Maximum Range per charge, ensuring it meets your target market's daily mileage requirements under real-world load conditions.
