SOLVED. YA fiction book set in Scotland - kid on bike in Scotland. Characters name is Mungo. [s]

From what i can remember a kid might have ran away from home or is travelling across the country on his bike. Might have been called Mungo. Think he had a nickname for the bike which was the title of the book?

I think there was a part where he stays in an abandoned house. Read late 90s early 2000s but was not a new book

Thats it, could have sworn it had Machine in the title but could not get a search result for it
