PICKED UP THIS BEATER TO SELL BUT FELL FOR ITS UNIQUENESS. ITS SHAFT DRIVEN, SINGLE SPEED. A BIT BIZARRE STARTING PROCEDURE AS WELL. THEN THERE THE FACT IT IS SO UGLY ONLY THE DESIGNER COULD APPRECIATE IT. THAT IS WHY I AFFECTIONATELY CALL MINE BELLA. THOSE WHO KNOW..WELL KNOW. ITS A HOOT TO RIDE AND WILL PRODUCE A 27 MPH WIND ON THAT HOT DAY. BUT THAT'S ABOUT IT.
