Hi,
I haven't cycled in the Iran so far. But I read bad things about cycling in Theran - so the Emirates are not worser than cycling in Theran. I only cycled in Dubai - and I enjoyed it. The connections between the cities are motorways and have a 2m sidewalk. Unfortunately every 50 m are bumps on the sidewalk
Regarding the maps. Do you take the ferry from Iran to Dubai? Then I recommened to buy the maps in Dubai.
Regards
Thomas
