Homemade Moped

A more innovative design was known in the UK as the Cyclemaster. This had a complete powered rear wheel which was simply substituted for the bicycle rear wheel, which originated from a design by two DKW engineers in Germany. Slightly larger machines, commonly with a 98 cc (6.0 cu in) engine were known as autocycles. On the other hand some mopeds, such as the Czech-made Jawa, were derived from motorcycles.
A further category of low-powered two-wheelers exists today in some jurisdictions for bicycles with helper motors – these are often defined as power-assisted bicycles or motorized bicycles. Other jurisdictions may categorize the same machines as mopeds, creating a certain amount of confusion. In many countries three wheelers and microcars are classified as mopeds or variations thereof. This practise is not restricted to the third-world, France and Belgium classify microcars such as the Aixam similarly or as "light quadricycles".
