Doing the math, you have about 110ft-lbs of torque up to 3500RPM. That would be 488.4ft-lbs of wheel torque. With 225/50 16 tires you get 573.8lbs of force on the pavement. That minus about 130N of rolling resistance equals to a little over 3.5miles per hour per second. But as you speed up air drag takes over until 48mph when your air drag will slow you down to about 3.3mph per second, assuming that you have a .29cd and an area of about 2.32m^2. At that speed acceleration will slow you down considerably from loss of motor torque since I calculated 3500 RPM to be about 48mph with your gear ratio and the tires I mentioned above. Your maximum grade you could climb theoretically would be less than a 14% grade, which isn't that bad, but you wouldn't be able to accelerate on it.
