Say you have an electric bicycle that is used daily, capable of a 30 mile range before needing re-fuelling and a speed range of 3-15mph.
What would be its likely lifespan, i.e. when would the whole thing have to be replaced?
I do not need exact measurements, just the general idea, as it is for a project for which i have to design an electric bike, which i know nothing about.
thank you!
Answer
The life span of an electric bike is mostly determined by the battery. Batteries can have a memory and if recharged before depleting it completely will reduce the capacity and can affect the range.
I would do some research on batteries. You can also look up motorized hubs to put on bikes, they make for the cleanest design.
Motors are rated in watts and most states have regulations that control the maximum amount of power that you can use.

Should China move the capital from Beijing to somewhere in the interior heartland because of overcrowding?
Q. I know that South Korea is looking to move their capital out of Seoul because of the same reason.
I read this article on the BBC News about the proliferation of electric bicycles in Beijing:

Then I thought, wouldn't moving the capital to an interior location help in economic development there?
Would you support such a move?

Answer
Most traditional capitals tend to be the largest city around. Though some countries, like Australia, have their capital in the what amounts to the countryside (canberra).
China has a huge government, moving it would be difficult. Certainly many of the government people might not want to go.
In addition, beijing is one of the traditional capitals. They could move the capital to Nanjing (another traditional capital). While nanjing is smaller, it is much more crowded than Beijing.
Finally, I really have not seen many reasonably sized cities that were overcrowded. For this reason many citis are moving their government functions out of the city to the surrounding countryside.
