Anti lock brakes: 2009Probably at least one of the following to be commonplace:
Anti lock brakes
All wheel drive
Some drive chain improvement -maybe belt, dunno
Kind of less bike related, but also some kind electronic integration -maybe tracking device, or direct transfer of information.
Given the last 30 years have given us index shifting, suspension, new materials and disc brakes for mainstream cycling (sure I'm forgetting some) it certainly wouldn't surprise me. And yes, while you could still cycle with no problem 30 years ago, I'll be the first to admit I think we have seen some nice improvements.
All wheel drive: 2006, New Jeep® Rubicon MTB($1,999.99). Electric wheel(s) in the front and it becomes all whee drive.
Some drive chain improvement -maybe belt, dunno
Tracking: Already possible through mobile phones.
