mountain biking oahu

Biking / Camping in Hawaii – Oahu?
I have a one week trip to Honolulu! and I would like to know how safe is it to bike around the island (Oahu)? Are there any trails for bikes?
Is a mountain bike a convenient way for visitng most touristic / exotic places or are there any other alternatives besides renting a car?
Thanks!
I also would like to know if is it legal to camp in public beaches? I will appreciate any advise or recommedations… Thanks!!!
i live on oahu and there a beaches where people camp but all of the people who are camping there are homeless so i dont recommend that. you could always take the tour buses to get around places or the bus system which is called The Bus (808-848-5555) if you call them and tell them where you are and where you need to go they will help you.
hope this helps
