Huh? Your post doesn't really make sense to me, not much has changed since '89 really, just go look at what the bicycles are in a department store, they've always reflected whats the current mainstream. Only difference from the mid 80s I guess the mountain bikes aren't rigid anymore. You missed the start of the BMX era sure, but I don't know why you'd wanna be apart of that.. but to each their own.

While its nice a bicycle can be so many different things I think the whole mountain bike + bmx introductions only helped push or further push the idea that bicycles are for kids or merely "toys" for grown ups.
