This Doona Liki Tricycle is the world's most compact folding tricycle, featuring a patented one-button fold that collapses in seconds to fit a car trunk or airplane overhead bin. This travel tricycle adapts for children aged 10 months to 3y+ and supports up to 20 kg, growing with each stage through adjustable seating and footrest positions. A height-adjustable parent handle delivers seamless steering control, while a UV-protective canopy, 3-point safety harness and foot brake ensure secure, comfortable rides. Built from rust-free aluminum, highest-grade fiber-reinforced polymers and high-durability wheels, this foldable tricycle blends lightweight portability with long-lasting strength for families on the move.
