Bikes are being improved upon since they are such a valuable and energy conserving mode of transportation. Trek will be offering two new bikes this coming winter that eliminate the need for a bike chain; the Soho and the District are built for the urban cycler who relies heavily on bikes for transport. Built with carbon-fibered belts, these bikes are guaranteed never to rust. The price tag for the Soho is just about $990, and the District is priced at $930.
