Very impressive! Real-world 70-80 miles in one charge on a 400 wh battery! I guess it would be fun and also a good exposure to sponsor an ebike tour where anybody can bring their ebikes and ride on predetermined stops and route to compare how far their batteries can power the different brands of bikes.
Addendum:
He had three (3) batteries with him?
"DAY THIRTEEN - The ride from Williamsport to Pottsville was by far the toughest so far, with several steep mountain climbs and numerous shorter climbs even before we reached the first mountain at Catawissa. I needed all three of my batteries. I was very glad to reach the Pottsville Ramada Inn. Since the trike didn’t fit in the elevator I had to store it in an alcove next to the elevator. [Day 13: 80 miles, 5843 ft.]"
