Why are these things not being pushed by mass???? Considering how light bikes are, they should be able to run off an electric battery and still have some go. I've looked at site after site and all I've found are home jobs that work mediocorely, DIY kits and one actual project that hasn't quite been completed yet. Wouldn't bikes be better off going in this direction? I mean, you wouldn't get the cool sound when revving you GSX-R's engine, but the environment people!!!! Lead the charge!
