Everybody will ride E-bikes. Instead of rim/disc brake discussions we will have heated Li-ion/Li-po battery discussions.

Your battery pack will be on subscription, once you fail to pay your dues to pay your bike will be immobilized (or if you fail to buy the newest iPhone to be able to communicate with your bike). There will be a chip to prevent any non-LBS from repair work.

Instead of Hex and torx screws there will be proprietary "rwerwtw-screws" that will change design annually and in between manufacturers. A disc rotor will be mounted with 6 different screws for no apparent reason other than to sell you the new 6-size-multitool that will work on your 2042 model, but not your 2043 model. Obviously there will be a different multitool for road and MTB. Also different screws for road and MTB.

There will be 28.25" wheels to combine advantages of 27.5" and 29". Those will be in addition to subgroups of 27.75" and 28.75". There will be threadless everything because of the threadless success off BB... and a new boost axle standard with 150 mm, because 2 more mm is exactly what keeps the noob from going to Whistler.
