[garygadget15] in the UK has an fascinating youtube page showing an electric bicycle. On his page titled, saving money the “green way” he has replaced his commuter cars and truck with one of these electric bikes. He then videos the commute with both to compare the results. The diy electric bicycle kit he uses is made by Cyclone is available in several wattage’s ranging from 180 watts to 1500 watts where they do a excellent task of showing the conversion steps. They’ve got sufficient detail that you might fab your own from salvaged parts if you felt like it.
