If you are planning on using your existing wheels, e.g. a 4 in diameter wheel then you will need to provide a similar gearing that the gear box provided. When you removed the box, the motor speed/torque are now 8775.00 rpm/10.47 oz in. A 4.5lb robot going up a pole with 4 in wheels needs around a 1:29 to operate at the peak power point. However, you can use a tiny tire, say, 0.3 in in diameter and do pretty well without a gearbox
