Trip 16.7 miles at 15.5 mph average in 1hr 30mins at assist level 4 and pedaled to assist motor. The Bionx kit performed great up the hills that would normally exhaust me at the end of the ride on a non assisted bicycle. While non assisted bicycles were traveling up the steep hills at about 4-5 mph, I was able to climb the hills at 8 mph without pedaling and as high as 14 mph with brisk pedaling. I tackled the steepest hills I could find in Palos Verdes. I found that most recreational bicyclists avoided these hills and the higher I rode the better the views. At the end of the trip, I still had half a charge left on the battery indicator. attached are the views of the test ride.
