That EM bike looks pretty nice actually. I watched some of the videos, seems to make good power.
But I agree, until the prices get into a range where "normal" folks can afford them I don't think they can ever seriously be considered an option for replacing gas bikes. Just like with electric and hybrid cars, they are often priced out the budgets of many people.
