I suspect not only bikes but most goods will see radical increases in price levels in coming years and it will not stop, given the current global political trends. I told the guy who drives pickup around the city cutting people's lawns that before long, he will have to give up on his motorized tools, go back to old fashioned rakes, brooms and mechanical grass cutters and pull his trailer with those tools behind riksha like bike (because gasoline engine will be forbidden before long and he won't be able to afford pickup run on batteries).
In short, we are going backwards and in some years hence, you will nostalgically think of todays 'cheap' times. Run of the mill bikes will flood the market though as most folks will bike to work per force, not that they will like it. Like in India, rural China today. Automobiles will be affordable again only by the rich, like in the pre-Henry Ford times in US.
