The concept of an engineered, hollow frame wood bike was developed in 2007 by Renovo founder Ken Wheeler. He was an avid touring cyclist who wanted a more stable, comfortable and durable bike for the rigors of touring. At the time, he was designing the Wheeler Express, an all-composite (carbon and fiberglass foam sandwich) aircraft, and in the analysis of materials used in historic wood aircraft he was surprised to discover that woods used in those planes had exceptional vibration damping and fatigue resistance in addition to their excellent structural properties. He felt a hollow bicycle frame of wood could offer a smooth ride, lightweight feel and durability he wanted. After extensive testing confirmed his analysis, he began producing wooden bicycles in 2007.
