Leg Build up Ride:
After riding about an hour in some very hilly terrain, covering 10.35 miles loop, the Shimano Range indicator shows 86 miles remaining.
(average speed 11.5 mph)
For this 10 mile ride, I used the pedal assist sparingly, just to assist in climbing the steeper hills.
The E-Bike weighs more that my Surly Long Haul Trucker, and it is noticeable on the hills (without using pedal assist).
