Abstract

The invention discloses a rapid body-building three-wheel mini bus using hands and feet. A rotation shaft in a bearing is vertically fixed at the front end of a frame; pedal plates, a transmission gear and a chain are arranged between the lower end of the frame and the rotation shaft of a front wheel; a group of transmission gears, a chain and a hand-rotated gear connected with the transmission gears through the chain, or a hand push-and-pull gear rod linked with the transmission gears in a meshed manner are arranged in front of a rear wheel; or a hand-rotated gear or a hand push-and-pull gear rod, a transmission gear and a chain are arranged between a rod jaw at the upper inclined part of the front wheel and the rotation shaft of the front wheel; and a group of pedal plates, the transmission gear and the chain are arranged in front of the rear wheel; when two feet of a user pedal on the pedal plates, the front wheel or the rear wheel is enabled to obtain forward thrust, and meanwhile, the hand-rotated gear is rotated by two arms of the user or the hand push-and-pull gear rod is pushed and pulled, the rear wheel or front wheel is enabled to obtain the forward thrust. The mini bus provided by the invention has the advantages of high speed and comfort of motor vehicles as well as energy conservation and environmental friendliness of tricycles, thus overcoming the defect of incapability of training hands and feet; and the mini bus is suitable for being used as a rapid body-building vehicle in city, and is especially suitable for the old to ride.
