How to have an unusual bachelor party?

A friend's wedding is coming up, and the guys and I are thinking about how to celebrate his last bachelor's day in a cool way. I would like something unusual, not just a bar or a club. Maybe someone knows unconventional ideas for fun for a large company?

How long does such a trip last? Are there any restrictions on the route or can you choose where to go? I wonder how it is organized - for example, who is driving the bike?
