The Urban Basin Bicycle Club holds open bike rides a round the Over-the-Rhine and Downtown area nearly every week. But it’s only once in a blue moon that the ride would fall on a Final Friday during … a blue moon. This “short, flat, happy, smile-making ride,” as its event creators describe, will snake around Washington Park, through Fountain Square and traverse through Main Street to check out August’s Final Friday happenings. Since this is a night ride, be sure to deck your bike out with sparkly, shimmery things and flashing lights for safety and swag. 8:30 p.m. Friday, Aug. 31. Departs from Know Theatre. 1120 Jackson St., Over-the-Rhine.
