It depends on how hard bike companies want to push it. If a bike has anything integrated with a battery (Di2, AXS, whatever) then I’d imagine that it’ll just become normalised, like hydraulic brakes have been (or, for that matter disc brakes!).
You say that but if it’s lighter, and sold as the next big thing you’d be surprised what people would buy. Regrettably the freds of the world will eat up what cycling marketers put down for them.
I can picture it now; no hydraulic lag - brake by wire! No air bubbles, no more DOT fluid! Shave grams off your bike! Tune it with a proprietary app!
The last thing we need is more electronic components on bikes.
It’s shit like this that gave me a headache when I worked on bikes in a shop - give me cables, levers, and serviceable derailleurs or nothing, please!
That thing (it’s not even a BSO) is precisely why tech startups need to get the hell away from bikes.
They are the future but stuff like this (and any number of weird bike renders from car manufacturers) just don’t make sense.
Bikes aren’t complicated - and they don’t need to be!
