I did this on my Fighter. With an Adaptto controller, which accepts a variable voltage input for regen, I added a variable voltage hall sensor to my brake lever body, then magnets to the brake lever. It used the dead zone before the pads would engage the rotor.Theodore Voltaire said:If someone figures out a way to hook the regen to a brake lever where it modulates just like the brake does now, that might be useful.
I managed to 'tune' it so precisely you could not tell where the regen ended and the physical brakes started.
While Adaptto is no more, I'm pretty sure Nucular can also do this, and I vaguely recall seeing some Ebike specific brake levers a while back that had this function properly integrated, but from memory they were very expensive. I think you can also do similar using an intercept on the brake lines.
I kind of do this currently with my LMX64 using switches that are run in-line on the hydraulic lines. These don't do variable voltage though so only cut the motor.
Anyway...point is, it is possible....just has a bunch of effort tied to getting it to work.
