Hi Onemoonrising, welcome to the forums!
That class is not actually "runnable": for that there has to be a main() method. Moreover the class you posted is Bicycle whereas the compiler message talks about a bicyclejava.BicycleJava class. Are there any other classes involved in this project? On the left hand side of NetBeans there is a list which tells you which packages are in your project, and which classes are in those packages. It might help if you described the contents of that "Projects" panel.
