On cars, under-inflating your tires can lower your gas mileage by about 0.2% for every 1 psi drop. As drivers, we know properly inflated tires are safer and last longer.
This principle is the same on your eco friendly Triad 3 wheel electric scooter. Instead of gas mileage we are talking distance the battery can travel. There are other factors your battery is sensitive to as well, climate being too hot or too cold, weight of the rider, degree of incline and operating at maximum speed. Terrain is also a factor when driving over high resistance areas like grass, gravel or sand. A lot of engineering improvements go into making Triad Electric Vehicles best in class.
Depending on the terrain, speed and weight or the operator, the battery is going to fluctuate on the distance. If you are driving on high resistance areas like grass you are going to use 2X the power to get across the same distance of grass as you would on pavement for example. You need 2X the amps to go over 5-6” of thick grass compared to being on flat pavement. One other major factor is tire pressure. If you are noticing reduced distances, first thing to do is check tire pressure. Low tire pressure adds drag and increases the demand for power up to 5x what it should be if the tires are under inflated. It makes the battery work really hard and you lose all the distance because you have quickly used up all the battery capacity. Proper tire pressure means less drag on the motor. Less drag, more distance. Be sure to monitor your tire pressures on all 3 wheels. The front should have 38-40 psi and the rear should have 48-50psi. If you are over 300 lbs. consider keeping the rear tire pressure at 55psi.
