Abstract: A transport vehicle including one or more accessory connectors for releasably locking one or more vehicle accessories to the transport vehicle. An accessory connector may releasably lock a first accessory within a first slot defined by the accessory connector and a second accessory within a second slot defined by the accessory connector. In some embodiments, the accessory connector may simultaneously releasably lock the first accessory and the second accessory within the first and second slots, respectively. The accessory connectors facilitate simple, quick, and easy attachment and detachment of vehicle accessories so that the transport vehicle may be easily converted between different modes of use.
