I used my battery for the first 40 miles, including the long uphill climb at the beginning of the park. But for the last 30 miles, I turned off my battery for most of the time, including the uphill climb for the last 5 miles (see elevation below). I ended up using only 3 of 5 bars on my 500 Wh battery (I never needed my spare 400 Wh battery that I carried for the whole trip).
Here are the stats:
- Distance: 70.3 miles
- Avg speed: 16.0 mph
- Riding time: 4 hr, 41 min
- Total ascent: 4,125 ft
And here are some pictures from the ride.
