It's a motorised bicycle. You should rent one because they're cheap, and the terrain is hellish for bicycles, especially the further afield springs and waterfalls. Be careful though as Thailand's roads are awful, although this far into the hills, you don't have much other traffic to worry about. Lessons are available. Bikes are 150 - 300 baht per day.
