Beschreibung
Zusammenfassung:	The invention relates to a transport device (100), in particular a stroller (102), comprising at least three wheels (120, 122, 124) for moving on an underlying surface (116) and a handle (112) for a user. At least one wheel (120, 122, 124) is designed as a drive wheel (130, 132) which can be driven electromotively by means of a paired electric drive unit (140, 142) in order to allow an at least partially electromotive support of a manual pushing or pulling operation of the transport device (100) by means of the user in an operating state. The drive wheel (130, 132) has an at least electromagnetically acting locking device (150, 152, 300, 430, 510, 610, 720, 800) which is designed to automatically block the drive wheel (130, 132) in order to quickly switch from the operating state to a blocking state in the event of a malfunction, in particular in the absence of the user or an at least partial failure of the power supply (144).
