sogood said:The other issue is, mechanical bikes are green. With NiMH/Li-ion batteries, it would no longer be a green machine but become another one of those environmentally polluting electronic gadget that has life cycle measured in terms of months.
The green issue is uber questionable. The issue of green, if you're going to use it strictly, has to include the production process, too. As such, how green are bicycles? How green is ore mining, CF production, painting, lubricant production, cleaning solvent production, tire production? And what happens to disposed tires, tubes, maintenance trash, lubes and solvents, and discarded parts?
New battery technology provides long lifetimes and many charges for said batteries. Further, research into small fuel cells--like to power cell phones, computers, and etc.--is going like gang busters. A fuel cell powered bicycle would be as clean as a bike today.
As for the electronics, they need not be short lived, either.
