I'm open minded about electric bikes, but the range and re-charge times are obviously the current(

) issues.
I do have issues with the green credentials though (and I think this also applies to the latest generation of IC powered vehicles that are packed full of complex electronics too). The biggest environmental impact any vehicle has is when it is manufactured. In fact the rule of thumb that I've seen is that the environmental impact of manufacturing is equal to the environmental impact of running the vehicle on fossil fuels for ten years. therefore to be truly green you want the vehicle to stay on the roads for as long as possible. Something like a small light IC engined fibreglass bodied car, with conventional ignition systems, economic to run and simple to fix would seem to fit the bill. Cheap and easy to manufacture, but nobody does.
Current IC vehicles (cars in particular) seem to be highly susceptible to being scrapped quite early in their potential lives due to problems with the complex electrical systems making them uneconomic to repair. Regardless of the lower emmissions etc, this hardly makes them green. The same of course applies to electric vehicles, but there you also have to add in the environmental impact of making and disposing of the batteries and generating the electricity at some sort of power station. The green thing is a big con IMHO.
I'd like a go on one of the Zero electric bikes though
