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.
