An intermediate stage for future indirect drive wheels on the floor thrust of the drive is in Künzelsau Schubstockrad of 1850. With two parallel side sticks to the driver came off the ground. His feet he used to steer the front wheel while he was moving the sticks thrust through a mechanism with arms and hands
The first was carried out using indirect drive cranks on the front wheel. Its inventor is disputed: either Pierre Michaux and Pierre Lallement. Lallement received during 1866, a U.S. patent on it, Michaux took over the driving principle in 1861 allegedly by the grindstone. Michaux and sons Olivier manufacturers marketed the ever-increasing demand for Tretkurbelrad in France. In the rest of Europe, it attracted attention only when Michaux at the World Exhibition in Paris in 1867 campaigned for it. Philipp Moritz Fischer built in 1869 by a Parisian model Tretkurbelrad for personal use (from Schweinfurt council backdated to 1853). The drive worked on rigidly to the front wheel axle mounted pedal cranks, whereby upon rotation of the pedals the distance traveled was equal to the circumference of the front wheel.
