Electric motors inherently have a high torque upon startup. This is 
because 100 percent of the motor's horsepower is always available. Quick 
acceleration can cause the rear wheel to lose traction, especially on wet 
surfaces. To prevent this, accelerate the vehicle gently by applying even 
pressure to the throttle. Once you become familiar with operating your Sparrow, 
you can improve your driving range (the distance your Sparrow will travel after 
charging the battery pack) by slowly and gently pushing the accelerator pedal so 
that you accelerate at an even pace, and by monitoring the amp meter. With 
practice you'll develop a balance between accelerating and amp consumption.
