Better figure on at least 80 Watthours per mile at 60 mph. If you come up with the best streamlining ever. Which is 425 mpgE. A 16 kWhr battery kept to 80% of capacity for longevity would give 160 mile range. Fortunately for EV DIYer's right now, there are leftover AMP20 cells still available from cut apart Fiskar packs for $0.34 per Watthr. Your pack will cost you $5,500 now. New cells are more like $1.20 per Watthr. You would need a 150 Watt generator to keep up with highway travel. Charging from 220v at 30a would take 2 hours. A 6.6kW onboard charger will be almost as big and expensive as the battery. This starts to become a 900 pound beheamoth as Terry's ZERO is. Streamlined as his bike is, he still uses 100 Whr/ mile at 60 mph.
