How can I calculate the capacity of an e-bike battery?

E-bike battery capacity is measured in Watt-Hours or Wh. This is the size of the “fuel tank” on the e-bike. Like a car, some motors guzzle fuel, others sip. To calculate the capacity, multiply the voltage (V) used on the bike by the Ampere-Hour (Ah) rating. For the Favorite ebike, for example, multiply 48Vby 11.6Ah = 556.8 Wh. More Watt-Hours equals more range for your e-bike.
