Transport Bicycle from Porto Airport to near the Cathedral. Do Bus, Train, Metro allow Bikes?
We fly in and out of Porto Airport and need to get to our hostel near the Cathedral. How do we travel?
Do buses, trains or metros allow bicycles onboard?

Bikes are allowed on the metro. https://en.metrodoporto.pt/pages/402
And of course, the great thing about having a bike is you've got your transport with you already.
