The HSB tri-hybrid bicycle concept is a full-scale working prototype designed to bridge the gap between small displacement motorcycles and large bicycles.
Developed by Tomas Bubilek over one and a half years, the concept integrates an electric motor into the front wheel and a small gasoline engine beneath its lightweight frame to optimize weight balance.
“The objective was to create a small, lightweight and modular bike to accommodate young people living in cities,” says Bubilek.
Able to run on either gasoline, electric or human power, the benefits of the HSB are evident in the context of operating anywhere motorized vehicles are prohibited. It can reach speeds of 70mph with the gasoline engine in use.
