Hi Gerry,
Sorry my French isn't good enough for a reply in French.
Just wanna warn you of the roadconditions on Java. Aviod the main roads, too busy and dangerous. Imagine more than 100 million people cramped on this island alone. Cycling in Indonesia is absolutely wonderfull, (I did it twice) but I went to outpost areas like North Sulawesi (sanger-Talaud) and the Moluccas. The further from the touristtrack, the more genuine friendly the locals. After 22 month's in Indonesia I'd say Java wouldn't be my first choice for Cycling in this wonderfull country.
Happy cycling!
