Shaft drive instead of chain, hooked up to internal hub gearing
hub gears or internal gearboxes and belt drives with bottom bracket pivot points
This sounds like my uni degree design project from 2002, designed all of this, had it at New Designers, Bike 2002 and a little 1/8th page article in MBUK … no interest at all! Anyway, copyrighted and even applied for patents* so if anyone does do this I’m sueing Spesh style! 😉
I’d like to see some form of adjustable front and rear suspension, so you could have 120mm front and back then with the flick of a lever 160mm front and back. Could even be electronically controlled, although I’d prefer a simple mechanical adjustment.
All this electronic shifting and suspension/damping controls, expensive gearing and forks and dropper posts are all making a simple bike very costly and complicated, soon we’ll be wanting a service history record and log book when we buy them.
* never did this properly and anything I did do has probably expired now anyway
