We often go outside to test the vehicle by ourself, some times, when customers come to
check the quality for their order, also will go out side riding with us. Most of time
is riding one day on the road, to climb the hill test the torque, to ride long time to
test the real range, to some not good road to test the shock suspension, to ride under
the rain to see is that ok or not. We can not say our product is perfect, but we are
going to perfect, following is one of the video we bring some our new models to climb
the hill in our city: https://youtu.be/RVGHzfdzKt0
