A drive mechanism for a handcycle has a master drive sprocket rotatably mounted on a frame adjacent a front wheel of the handcycle, and positioned away from a driver seating area. The drive mechanism further includes a drive chain operably connected to the master drive sprocket and adapted to operably engage the front wheel. An elongate extension element extends from the frame adjacent the front wheel towards the driver seating area. A pair of hand cranks are rotatably connected to a pivot element of the elongate extension element, each of the pair of hand cranks terminating in a hand grip. A transmission operably connects the pair of hand cranks with the master drive sprocket, such that rotation of the pair of hand cranks turns the master drive sprocket for driving the front wheel. |
