1840 years of England's blacksmith McMillan, inventor of the wooden wheel in Delaisse based on improvement. He installed on the rear axle crank, and then crank and connecting rod to connect the front of the pedal, and both front and rear wheels with iron, large front, small rear wheel. This was finally a real human feet off the ground, trampled by the feet of alternating scroll wheel drive vehicle moving forward. Pierre Michaux
