Test riding bikes can be the hardest thing. Dealers balk at letting you. Sellers as well. If you are not sure which type/style you want, it can be tough figuring it out.
My first thought when I read this was what is your height/weight? If you are a big dude ( I don't just mean fat ) you will need a big bike to feel comfortable. Ever saw a 6'6" guy on a 600? That plays into the safety part as well. Take your time choosing and remember, it's bike season. This is the time of year when people get the fever and quickly go out and get one just to sell it in the winter because they realize it doesn't fit their lifestyle.
Oh, and make the first one a bike you don't plan on keeping forever. Make it cheap and ride it a LOT. Move up after you KNOW bike ownership works for you.
BTW, if you get a bike and sell the P-car, I will personally come out, kick your butt, ride your bike till empty and scratch the tank.
