A mountain bike (or road bike) can easily be adapted for general gps or geocaching use by fitting a gps receiver handlebar mount. There are commercial handlebar mounts by both gps manufacturers and third-party suppliers available for most of the common gps receivers used for geocaching, but these can be expensive as they are imported. A simple homemade mounting can be made by the average DIYer in an hour of two and can be attached easily to the handlebar by Velcro. An example of such a homemade mounting is pictured. This particular mounting made of perspex, Bisonboard and Velcro, fitting both a road bike and a mountain bike, has done many, many kilometres of service over varying surfaces with no problems.
