By literature and materials, and on-site data survey and so on, based on mixed logit model, this paper makes survey and analysis of the demand choice variables of mountain biking sites, and reveals that the trail condition and site design significantly influence their site choices of bike enthusiasts. Especially, the sites with higher quality trail conditions and routes design perfection have more challenge. At the same time, we applied a generalized estimating equation to the demand data for use in estimating the annual outings and in calculating the consumer surplus of mountain biking activity in this paper. As a whole, this studying results aim to highlight the importance of path evaluation, site management and resources management and to provide the reference and basis for industrial development of mountain biking movement and park management plan. 
