Hello All Ebike Gurus! How much power do you think it takes for you to go from San Francisco to San Jose in California? The reason I asked is because we have a group of people interested to doing long ride in the Bay Area. Let say if you + the ebike + the battery weight = 300 LBS (136 kg), and the trip is 70 miles (112 kilometers) 1 way and your battery is the 48V LifePO4, and your average speed is 20 MPH (32 kph), on flat + typical wind resistance on a sunny day, throttle ony (no pedaling assume this is for a duration contest), then how much aH (amp hour) of the battery power do you need? I appreciate everyone help & input.

Here's the link to the bike path from San Francisco to San Jose:
