The invention discloses a dual-drive balance wheelchair. According to the dual-drive balance wheelchair, two balance monocycles the same in specification are used, and pedals of the two balance monocycles are connected through thrust bearings, a connecting shaft and shaft sleeves; and the thrust bearings are installed on center tubes at the tops of the balance monocycles, a transverse beam is located on the thrust bearings, and a chair body is fixed to the transverse beam. The hole distance of supporting tubes at the two ends of the transverse beam is coincident with the wheel distance and slightly larger than the diameter of the center tubes. After the chair body is erected, free operation and free rotation of the balance monocycles can not be influenced. The front-and-back inclination angles of wheels are controlled through the pedals, and the balance monocycles are not influenced by each other. The left wheel and the right wheel can be vertical at the same time, and the wheelchair keeps static; the left wheel and the right wheel can also slant by the same degree, and linear forward moving or linear backward moving is kept; and the pedals can be further controlled to enable the left wheel and the right wheel to be different in inclination angle, the speed difference is generated between the left wheel and the right wheel, and steering or turning is implemented. As extension tubes are installed on the pedals, a user can conveniently operate the pedals when sitting on the chair body. A small shelf convenient to disassemble and assemble is additionally arranged at the front ends of extension handles, and therefore use is convenient.
