Alright, so I narrowed it down to Windsor The Hour in white and Windsor Clockwork.

If I get the Hour, is the brake interchangeable between the rear and front wheels? Because on BD, it lists it as "FREE Rear Brake and Lever." Does that mean I can only use it on the rear wheels? I was thinking of making it into a fixed bike and moving the brake to the front wheels. Is this possible? Or should I just get the (arguably) uglier black Clockwork.
