Death Valley postie bike ride over spring break

Death Valley postie bike ride.

I've been watching Youtube videos of the Australian postie bike rides and they look like a lot of fun. I'd like to do something like that at Death Valley during spring break March 20th thru 26th. We would camp somewhere near Ballarat on BLM land and do day rides around the area. Postie bike is the Australian term for a Trail 90 or 110. Other similarly slow but off road capable street legal bikes would also be welcomed. Do a Youtube search for postie bike. Anyone else interested in seeing Death Valley from the slow and cheap vantage point of a postie bike?
