do u like BIKING and at what speed?

i like biking in different places. Im looking forward to bike the himalayan mountains. A very good place to have adventure and travel. My usual speed depends on the road. For high ways on plain surface, i go for 25 to 40 km per hour using mountain bike. on inclined surface going up, the slowest speed is 6km per hour to 20km per hour. depending on the angle and the condition of the street. downhill speed is about 35 - 60 kn per hour depending again on the street. HOw about you?
