Homemade Moped

History
The term "moped" now only applies to low-power (often super-economy) vehicles, but pedals were fitted to some early motorcycles, such as the 1912 Douglas. Pedalling away from stationary was a great improvement over "run and jump" and light pedal assistance (LPA) was valuable for climbing hills. Better transmissions with wider ranges, better clutches and much better engine performance made pedals obsolete on most motorcycles by 1918 but the pedals on mopeds remained valuable for their original purposes as late as the 1990s.
The earliest mopeds were bicycles with a helper motor in various locations, for example on top of the front wheel; they were also called cyclemotors. An example of that type is the VéloSoleX brand, which simply has a roller driving the front tire.
