Riverman said:The battery technology is definitely starting to improve a little but it pains me that a lot of research is going into how to charge batteries as fast as possible rather than increase their capacity. This is almost solely because the motor industry require batteries to charge quickly in order for the electric car to become a more viable mode of transport.
I'm not particularly bothered about the concept of an electric bicycle, the issue is cost. In the long term I think that people are probably a bit optimistic about the costs of what goes into current batteries in electric and hybrid cars, let alone for anything else that might use the same materials.
I didn't go to the bike show in London but I gather there were a great deal of electric bikes there. On the eco and money saving thing someone once told me their electric bike cost about 50p to charge, which is a major disadvantage.
