The gray Dahon Matrix (Joe Murray design) model has WTB wheels with 26x1.6 Continental tires, Shimano disc brakes, Suntour shocks, Richey handlebars with an adjustable stem, SRAM Grip Shifters for a 3x8 drive train with a Micro shift front derailleur and a SRAM rear derailleur, and folding pedals. $200.
The blue Dahon Expresso model has 26x2.0 Schwalbe Big Apple tires, rim brakes, an adjustable stem, SRAM Grip Shifters for a 3x7 drive train with a Micro shift front derailleur and Shimano Altus rear derailleur, and a kickstand. $150.
Both bikes have very similar 7005 aluminum frames. The Expresso is labeled Large, but both bikes were used by riders ranging from 5'1" to 6'2". The adjustable stems and seatposts can accommodate many sizes. These bikes were taken on our travels, and have been recently ridden. We have upgraded and no longer need them. Each bike is rideable, but could stand some TLC.
$200 for the Matrix, $150 for the Expresso, or $300 for both.
