Bicycle Tag of bike

So the new one: Can we have a clue please? An actual clue, from which someone who doesn't know the three-boled tree on the south side somewhere upstream of Richmond could solve the riddle?

That's right, I just used the word 'boled'.

Surely the riddle is 'in what location was the picture taken'. Loads of clues to this have been given, not least the actual picture, which is a massive clue. You could also easily find it if you went out looking for it - and you know where to look. Why should every tag be totally solvable without leaving your computer?
