Bike storage
 

Me and a friend of mine are planning a trip from Italy to South Africa through the west coast.
Since we have two months of vacation at a time we can not complete it all at once. Then we need a place to store our bikes for about 10/12 months, and then continue the journey later.

Can someone advise me a country in West Africa between Senegal and Nigeria where it is possible to leave our bikes for so long period???

Any information, suggestion will be appreciated

Thanks
Ciao
