It's less carbon intensive to charge an e-bike on coal than it is to power an F-150 Lightning EV on wind/solar.
Let's do the math using the 2014 IPCC numbers of carbon intensity of various energy sources over their life cycle:
820g CO/kWh for coal
48g CO/kWh for utility solar
11g CO/kWh for wind
An F-150 Lightning uses 49 kWh/100 mi. An e-bike uses about 1 kWh/100 mi.
An F-150 Lightning on a 50/50 wind/solar mix causes 1.42kg CO2 per 100 mi.
An ebike on coal causes .820kg CO2 per 100mi.
