So here is a video from today of me riding down our road ( we live on a mostly gravel road) normally only people who live on it drive down it so not much traffic.
They have a few places to go off road off the sides so i wanted to check those out, It got a little bumpy but not to bad. All of this was in Eco mode with only one battery plugged in, but I did have the 2nd one with me just in case i ran out of juice.
So far I haven't been able to do the advertised 20 miles on a single pack Kinda disappointing. but maybe the battery's will get better as i use them. they are Li-Ion packs.

Thanks for watching.. This video was un edited Raw upload from the camera.
