There was a small issue with one of the bikes, so in the morning we visited a bike service shop. The owner did not speak english, but understood what we wanted from our gestures and in few minutes we were ready to go to Portugalete. We got there quite fast – no mountains, just flat city roads.
The top thing in Portugalete is a suspension bridge over the Nervión. It is a unique structure, it is the only one of its kind in the world, you get on a small platform – and then it is moved to the other side of the river.
