The given Twitter post does not relate to a maintenance report feedback to a public flat house. The post mentions a product, specifically a bottom bracket for a mountain bike, and does not contain any language that suggests a complaint or feedback about a maintenance issue in a public housing facility. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "product" to indicate that the post is about a product mention, rather than a maintenance report feedback. The "explanation" field provides a brief explanation for why the post does not relate to a maintenance report feedback.
