Can e-bike increase speed with battery changes?

  The speed of e-bike is determined by the drive that powers it. Of course, the bike can run at speeds greater than 30 kmph. Have you read information about Tesla Roadster? Do read about Tesla technology.

  but wont the engine which runs the drive also matter??.. so if the engine can provide more power to the drive the speed will increase... am i right??

  The speed depends on the drive, the transmission system and the vehicle aerodynamics, as in a vehicle using any other system. The motor(dont use the word 'engine'to describe it, please) is to be designed so as to work efficiently at a higher RPM as we require. Using suitable gears for shifts, (just as we speak about 4 speed transmission, 5 and even 6 speed transmission)will increase the speed of the vehicle. The other factor is the power of the motor. In a 150cc engine of a petrol fed two wheeler, we get an average of 13.5 bhp, about 11kW from its engine. For a performance like that from the e-bike, we need a 11kW motor.
  The basic limitation for e-bikes is the power storage. Imagine the size of the battery powering a 11kW motor(now thats crazy). Many technologies, if brought down to feasible rates(technologies like the ultracapacitors) can make us powerful enough to innovate electrical beasts on two wheels. Hope they research hard for us people who are in the need of speed, the electrical way...
  
  
  P.S. This is what I think is right. I may not be right. So, please correct me if you find I am wrong.
