Vehicle, Mobility and Transportation Design Silence Electric Bicycle by Yi-Sin Huang Silence is a brand new control concept bicycle. It was designed to have its own sensory organ where Karl H Studio used 4 technologies, radar, LED, detectors, and computer. Silence can tell the current status to any rider based on their own riding conditions. Sincerely, Karl Huang designed Silence is to make a bicycle to dedicate for the hearing-impaired friends to help them to keep out from the dangerous. Even they are in a peaceful world without any sounds, they still have the rights to enjoy unfettered and safety riding.
