Electric/hydraulic brakes

Shimano have filed a patent. Force transducer in the lever coupled to a
hydraulic pump & brake caliper.

Makes one wonder what a bike-sized Citroen-style power brake compression chamber would weigh. I loved my Citroen SM, basically a Maserati designed by Citroen's most futuristic thinkers but it was so fragile that at one stage I had three, one to drive till it broke again, one in perfect order on standby, and one being fixed after it broke at a specialist fortunately only about fifteen miles from Cambridge; it was the carelessly shortened engine that broke, never the brakes or other proven Citroen bits straight off the DS.. I had a couple of DS too, one when they were new in South Africa which I liberated from the production budget of a film I directed while still a student, one as a near-Classic in Australia, where it proved itself tough as nails. You could have a softly suspended bike with superior brakes, glide across the bumps and the potholes and tramlines...

That’ll be a hoot when your battery goes flat during a ride, although if
every bike ever made from this point onwards is an e-bike, it’ll be less of
an issue.

Nope, just mount a small internal combustion engine down there above
the BB and you can keep the battery charged :-)
