stationary bike for exercise, $70

I bought the following exercise bike a year ago:
http://www.amazon.com/gp/product/B002JB40MC/ref=oh_details_o06_s00_i00?ie=UTF8&psc=1

It has been minimally used, proudly...
and so is in good condition.
I'm selling it for $70. Interested please contact at 650 452 2870 or huajiaw@stanford.edu. Thanks.
