I'm all for technology but i just don't see electric bikes taking off any time soon, my main issues with them are;
Battery hire, kind of wipes out any savings in fuel,
Noise, what the point of a motorbike if you can't have a mean sounding fire-spitting exhaust?!
Charging points, up north there are hardly any so you're relying on charging it at home, you might find a couple outside large supermarkets/ikea type stores, but range will be an issue
Long term maintenance, i know batteries don't last forever, and they lose capacity over time, so how much is it going to cost to have them replaced down the line?
