Hi, Folks,
I am from India, currently stationed in Singapore and I am planning to go on a road trip from Germany to Athens, with my friend in Germany. We plan on renting bikes.
>It would be great if you could suggest some place where I get bikes on rent for pickup at Germany and drop off at athens.
>>Also, I am planning two weeks (15 days) for the trip.
I hold an Indian 2 wheeler & 4 wheeler license. Will this be valid for driving across Europe?
The map below shows roughly what we have in mind

I have attached an image also).
See my Map on Google Maps
Karlsruhe (Germany) --> Salzburg --> Bratislava -->Budapest --> Belgrade -->Skopje--> Athens
I am pretty new to long distance biking, and this is my first time in Europe. We are on a shoestring budget also, and plan to camp in tents whenever we can.
I will be very grateful for any and all advise I could get, places that are must go, or avoided, routes, alternate routes, camping/stay tips, gear and paperwork advice
Thanks in advance
Sharath
