electric bikes perform in terms of speed, motor power,range, and elevation gain depends on many factors. The most important factors are listed here with the most important at the top(generally speaking):

  1. battery capacity (measured in volt-amp-hours)
  2. terrain (number and incline of hills)
  3. e-bike speed (max speed from 25-32km/h)
  4. Motor power: usually from 250W-500W. Europe at most 250W, US can be 500W in law.
  5. wind conditions (going 10 mph against a 10 mph headwind feels like 20 mph to the bike)
  6. weight of rider and baggage, loading weight, usually 100KGS at most as standard.
  7. correct tire inflation (under-inflated tires slow you down)
  8. motor/controller/drive system efficiency.
As you can see, battery size ranks at the top. With a pair of big car batteries mounted on a trailer, you can go for hours. To double your range, double the size of your battery pack. System efficiency ranks at the bottom because most systems are 85% to 95% efficient. The speed you go makes a big difference in how far you go.
