Hi,
I've never ridden an electric bike before but I'll probably end up with one eventually at some point in the future (for the moment the price is prohibitive). I'm curious, has the technology changed much in recent years and are there clear signs of continuous evolution? Are designs improving all the time, battery life extending, weight reducing etc., or are the general designs well established and unlikely to change much? In short, I know nothing about ebikes and am looking for a quick summary of where the technology is at and where it looks like it'll be in a couple of years time.
