'Zìxíngchē' literally means 'self-moving vehicle' — 'zì' (self), 'xíng' (to move or go), and 'chē' (vehicle or cart). Unlike English 'bicycle', which emphasizes two wheels, the Chinese term highlights human-powered motion. It's the standard, neutral term used across mainland China, Taiwan, and Singapore for the common two-wheeled pedal-powered vehicle.

This word appears frequently in daily life: commuting, traffic regulations, fitness contexts, and environmental discussions. It’s not used for motorized scooters or e-bikes unless specified (e.g., 'diànzìxíngchē'). While older terms like 'jiǎotàchē' (pedal car) exist, 'zìxíngchē' is universally understood and preferred in both spoken and written Mandarin. Children learn it early, and it often appears in beginner textbooks alongside transportation vocabulary.
