is there a motorcycle dealer / leasing accept credit payments motor using bitcoin?
It sounds great,I would say a dream for every motorcyclist is to take a motorcycle,and it would be astounding to achieve this goal with such an "easy" way like bitcoins.If there is something indeed or something similar please inform the people!!
Unfortunately I don't think this service exists. I have never even heard of such a thing being popular with normal fiat so it is unlikely that it will happen with Bitcoin anytime soon.
Why not start one yourself? Make a website to lease/loan motorcycles for Bitcoin in your city and advertise it (local classifieds, newspaper, radio, etc.). This is a great way to spread the knowledge of Bitcoin also!
