When evaluating trikes, prioritize the frame material, typically high-carbon steel for durability or aluminum alloy for lightweight performance. For motorized or electric trikes (e-trikes), verify the motor power (typically 250W to 1000W+), battery capacity (Ah), and range per charge. Ensure the braking system utilizes disc brakes for superior stopping power, especially for heavy-duty cargo models. Additionally, check the load capacity, which should meet a minimum of 150kg for passenger models and 300kg+ for cargo-specific versions.
