Since the world is not flat and some people do live on hills 2000+ feet up in elevation from where they travel to and from it makes sense to make ebikes that will handel this efficently at a decent speed for a 6 mile strech up hill. If anyone can do such a round trip of 12 miles or so POST IT. A video and a elevation map of the trip along with watt hours used on the round trip along with bike weight and batteries used may open up a a great testing platform for any new products that may meet any demand other than just commuting in flat areas.As it is there are no products that I know of that will meet this demand carrying a rider of up to 250 lbs vary efficicently.Or make it at all at any speed.

The video didn't have the wide angle so when climbing the hill it was pointed at the ground too much.The trip included going down to the ocean then back to where I started in 11.1 miles using 6.4 amp hours on 72 volt pack.Also using one gear ratio.You may notice that it took anout 4 amp hours to go about 4 miles up a average 20* grade with a 2000 ft elevation rise in 20 minutes.Now lets see a hub motor ebike do the same with a 26" wheel.
