Titan is Saturn's largest moon. It has lakes of liquid methane and ethane near its north pole where a human colony would be established. Transportation on Titan would use non-motorized surries that are pedaled like bikes to keep colonists healthy. The atmosphere would be distilled to extract hazardous chemicals, and satellite dishes would allow communication. Colonists would live in homes made of durable materials like titanium and aluminum with vacuum insulation and an inner layer protecting against Titan's extreme cold.
