E10 will be a bit of a pain for motorcyclists, fuel injection motorcycles have a bit of built in compensation and its all automated. Our older carbed bikes will need a really good go over of the complete fuel system, fuel lines that are compatable, any carb rubbers and O rings may need to be changed and some jetting up will be needed, there may also be carb iceing problems associated.
My view on electric bikes and all other electric vehicles, electric motors are a great idea, massive torque so no gearbox is needed, and fairly light weight compared to a similar power ic engine, the downside is should the controller break down its major expense and charging times are very long and battery capicity is not that great, so no long drives in a day, and now to the big one there is not enough lithium in the world to replace all the ic powered vehicles that are around now, the alternitive is sodium it is very plentiful but sodium battries are still a very long way off, fuel cells are a great idea and so is hydrogen as a fuel either for fuel cells or modified ic engines
