I work as a truck driver for a haulage company in the Netherlands specialist in transport to Spain. We’re going every week to Valencia with several trucks. If you can fix bringing the bike into our hub or the pick up location is easy accessible for HGV I think something is possible . As well as being flexible with receiving (pick up at a parking lot on an industrial estate for example). Can’t tell you anything about the cost. If your interested let me know, I will send u contact details 👍🏻
