For the Hammacher Schlemmer trike, also can add one small spanker (no, not that thingee your boy toy/grrrl pal is thinking about), butt seen via Giggle (sp?) on that Wicked Pee thingee, "a gaff rigged fore-and-aft sail set from and aft of the aftmost mast".
(Also is taller than that silly little flag thingee as supplied with the HS trike.)
So, tick off one to throw in the box? (Again, it is a large box, but sail/mast/rigging is all collapsible, and sort of sun-resistant materials.)
Maybe $100-$200 to add to order costs. Price approximate.
So in ebiker terms, can assist travels using wind power to cut or entirely replace bettery consumption!
