- Cross-posted in the Indonesian forum!
My partner and I are starting to plan a 3-4 week trip in Indonesia, most likely starting in Jakarta, where we will buy two local 1-speed or 3-speed bikes and use those to ride around the country. We have actually done this many times before in several countries (India, Sri Lanka, Vietnam, Cambodia, Laos, Tanzania) and it's worked out pretty well, as we usually only ride 40-90km/day and have very little belongings.
I have been reading through many blogs and posts about cycle touring and I have what probably sounds like a stupid question... is it possible to avoid hills bicycling in Indonesia? I don't mind them so much but my partner's knees can't do them. I know Indonesia is in general an extremely hilly country, but then again we have traveled through lots of different terrain and so far have managed to avoid hills by sticking to coastal routes or just being very careful in planning which roads to take. Asking advice from other people that have direct experience (especially bicycling experience) in the region has also been so helpful.
Hopping on an occasional bus/boat/train to skip ahead is fine, but we would like to use our bicycles as transportation as much as possible. For a start, bicycling from Jakarta to the eastern tip of the island, and then over and through Bali sounds great. But is there a way to get there that avoids hills, and then, after that, does anyone have any suggestions on potential routes?
Thank you in advance!
