Novelty: a bicycle’s mechanical motion arrangement - rotation of the drive shaft either by electric motors or by muscular force applied on the pedals. Constitution: the pedals (1A ,1B) adapted to the extremities of the arms (2A,2B) the other extremities of which are firmly adapted to independent driving shafts (3A,3B) which driving shafts are displaced to operational positions at the framework of the construction so that -compared to ordinary bicycle’s arms- the length of the foregoing arms (2A and 2B) are multiplied; toothed arcs of great length (4A,4B) are meshed with toothed wheels transmitting the motion via check mechanisms to the shaft 9 wherefrom the motion is conveyed -with suited transmission ratios and in the suited rotation sense- to the final shaft 8. Embodiment: use in vehicles of any kind, in lightweight seacrafts, airplanes and flywheel drive engines as well. |
