If you want an authentic Bali experience with knowledgable and engaging locals, then we highly recommend Bali on Bikes. Our experience was one of the highlights of our trip to Bali. Our guide Moon's English is very good and he provides a wonderful insight into the Balinese culture. The ride is easy and mostly downhill. It was never a problem if we wanted to stop for photos (or bathroom) and the lunch at Bob's compound was absolutely delicious.
