Options are listed on the web site [http://www.optibike.com].

There are three tire choices, all from Schwalbe: Marathon Supreme, Marathon XR, and Fat Albert. No saddle options, though the stock WTB feels comfortable enough for me. They also insisted on including WTB momentum pedals which I have no use for (I'm riding with Atomlabs GI platform pedals).

I live in Colorado, so I picked up the bike at the factory. Pictures in the owners manual show it crated up in heavy cardboard packaging with the bike bolted down (to a piece of wood?) at the dropouts. Wheels, pedals, and fenders are separated from the bike.
