It's going to take a while. Unfortunately there is still a huge gap in terms of energy density and $ per kilojoule or Wh stored between a $650 (equivalent value in PKR or INR currency) two stroke motorcycle, and an electric motorcycle with equivalent engine power and range. Just the batteries for a decent electric motorcycle alone cost 8x more than a typical developing nation locally manufactured motorcycle or motor-rickshaw.
Power distribution would be a problem (well it already is) with the uptake of electric vehicles - although I'd imagine if solar panels get cheap enough everyone could have one at home and just swap a spare battery in over night. Fuel is already quite expensive in India (around the same price as Europe), so it might not be that long a wait.
