Some of the less expensive e-bikes used bulky lead acid batteries, whereas newer models generally used NiMH, NiCd, and/or Li-ion batteries, which offered lighter, denser capacity batteries. Performance varies; however, in general there is an increase in range and speed with the latter battery types.
The environmental effects involved in recharging the batteries can of course be reduced. The small size of the battery pack on an e-bike, relative to the larger pack used in an electric car, makes them very good candidates for charging via solar power or other renewable energy resources. Sanyo capitalized on this benefit when it set up “solar parking lots,” in which e-bike riders can charge their vehicles while parked under photovoltaic panels.

So your motor is limited to a peak of 1490 watts. This is where you have to be careful as a number of e-bike motors are sold not at peak rating but at their sustainable rate. That 1000w rated motor might actually be capable of 2000w and be a violation.
Electric bikes are a green alternative to driving a vehicle. Studies carried out in several towns and cities show that the average car speed in rush hour traffic can dip as low as 18 to 20 mph. Electric bike speed can be as high as 15 mph. With an electric bike, you can reduce pollution, improve fitness, and still arrive at the same time as your car-bound colleagues.
With clear rules on how and where to ride an e-bike, stands to benefit. Local bicycle shops and manufacturers will see increased business and their customers will no longer be confused; people who already ride e-bikes can more easily understand where to ride; and new bicyclists who may be discouraged from riding a traditional bicycle due to limited physical fitness, age, disability or convenience will have new transportation alternatives.
