We booked a cycle tour through Tour east who use Sobek. They picked us up from our hotel on time and drove us up to Mt Batur for morning tea overlooking a breathtaking view of the volcano and lake batur. It was amazing. Then with a safety brief and safety equipment we began our leisurely ride down to Ubud.
It take approx 2hrs to ride downhill all the way, in fact there is barley any pedalling involved! The brakes on the bike get a good work out though;-)
They looked after my family with a child seat on the back of my bike and a mini bike for my 8yo. They follow you all the way with a support vehicle so if you get tired or like my kids they get to ride in the bus while we ride.
They give you a running commentary of the Indonesian way of life, through, rice paddy fields, to coffee plantations and walk you through a family owned home. It is a very beautiful and peaceful place. Finishing of with lunch at a restaurant over looking a rice field.
I highly recommend doing this tour and would most definitely do it again.
My only criticism is like some of the other bike tours company's Sobek need to invest in a tandem bike as we where told they had one when in fact they didn't. Communication break down.
