There are laws in many places about what power, speed and characteristics an electric bicycle can have and which still uses bike paths. That’s why you often see bicycles with maximum speeds of 20 or 28 mph. There are several companies that will sell you an electric bicycle that exceeds these limits or that can be easily modified. My electric bicycle was limited to 20 mph before five minutes and a screwdriver turned it to 46 mph, which I do not recommend. Many of these bicycles have pedals or kits to add pedals, which really does not help differentiate bicycles from electric bicycles, or from mopeds or motorcycles.
