context_page_description: A treadle bicycle is a bicycle powered by a treadle instead of the more common crank. Treadles were one of the mechanisms inventors tried in order to position the pedals away from the drive wheel hub before the development of the bicycle chain or instead of it. Treadles have also been used to drive tricycles and quadracycles.
