How to calculate the gears which can maintain certain speeds on inclines when power is maximised?

I've got information for the mass, chassis dimensions, drag coefficient, incline angle, gear ratios and some other info. But I don't understand how I can judge the gear off of the angle of incline and the speed. Any help is appreciated. Thanks

    assuming you want power to climb the incline at a certain speed?

    pick a speed, calculate the force needed to climb the incline, due to gravity and friction. From that you can get the energy. From time and energy you can get power.

    as to the gear ratios, it depends on the engine, wheel size, etc. Gears just reduce the RPM of the engine to the RPM of the wheels. The latter you can get by time to climb the incline and diameter of wheels.
