A pedal-powered wheelchair having a steering dolly pivotally mounted at a rear of the wheelchair. When the upper end of a first steering lever is pulled and the upper end of a second steering lever is pushed, a first steering linkage connected to the first steering lever pulls forward a first side of the steering dolly and a second steering linkage connected to the second steering lever pushes rearward a second side of the steering dolly. This causes the steering dolly to turn clockwise to initiate a left turn. When the upper end of the first steering lever is pushed and the upper end of the second steering lever is pulled, the first steering linkage pushes rearward the first side of the steering dolly and the second steering linkage pulls forward the second side of the steering dolly. This causes the steering dolly to turn counterclockwise to initiate a right turn.
