For Sale/Wanted Used bike wanted - preferably electric

I am looking for a used bike with rear racks to cycle the Camino from Lisbon to Santiago or vice versa - depending on which direction the prevailing winds blow. If possible I would like to buy, rent cheaply or borrow an electric bike. I am in my late 50's and looking for all the help I can get including tips on how to avoid hills, yummiest food and wine, where to do laundry, how to optimize having the wind at my back, gear tips, cheap clean charming places to stay, etc. Will be arriving in Lisbon April 21, 2019 and could pick up bike wherever needed but would be a bonus if in Lisbon. Thanks in advance for any tips you have to offer or leads on where to find a bike.
