A movable carrier includes a main body, a first wheel, a driving module, a first support member, a second wheel, a seat, a first handle and two first switches. The first wheel is pivotally connected to the main body. The driving module is disposed in the main body. The first support member is connected to the driving module. The second wheel is pivotally connected to the first support member. The seat is disposed on the main body. The first handle is pivotally connected to the seat and has a trigger portion. The first switches are disposed on the seat. When the first handle rotates with respect to the seat and the trigger portion triggers the first switch, the driving module drives the first support member to rotate with respect to the main body, so as to increase or decrease a distance between the first wheel and the second wheel.一種移動載具，包含一本體、一第一輪子、一驅動模組、一第一支撐件、一第二輪子、一座椅、一第一把手以及二第一開關。第一輪子樞接於本體。驅動模組設置於本體中。第一支撐件連接於驅動模組。第二輪子樞接於第一支撐件。座椅設置於本體上。第一把手樞接於座椅，且第一把手具有一觸發部。二第一開關設置於座椅上。當第一把手相對座椅轉動，且觸發部觸發第一開關時，驅動模組驅動第一支撐件相對本體轉動，以增加或縮小第一輪子與第二輪子之間的距離。
