I've been riding my 3-speed IGH cruiser lately and enjoying it immensely as well as deriving (for me,IMO) a better workout than with an e-bike or MTB. This bike is about 27 pounds with some recent improvements. I would like to assemble or purchase a true cruiser-style (like the old Schwinn cruisers, not a retooled MTB) without starting with a $2000+ custom frame, and end up with a five or so pound lighter bike. Any ideas? BTW, the current bike (below) has a Kent Eriksen Ti seatpost and Ti-railed seat, and could be made lighter by rebuilding the rear wheel with a lighter rim and spokes, changing the steel handlebar to carbon or aluminum and installing an aluminum crank.
