One of my old e-bike has a broken component and is subjected to upgrade, as most of the vendors have either disappeared or declare the component as end-of-lifecycle.
I'm considering Grin PhaseRunner ESC:
and its successor, Grin BaseRunner V4/V5:
as the next ESC, it has good customisability & compatibility with many components. But there is one problem: According to its manual, it can only run with a PAS or torque sensor, or both.
Unfortunately the only standard Bottom bracket standard I could use are SRAM GXP or SRAM DUB, none of which has a compatible sensor interface.
So my only option is to use no sensor at all, and rely on throttle control. I may be able to upgrade to an optical flow based sensor later, which is agnostic to BB standard. Also, Both ESC can communicate with a cell phone with bluetooth, so a display appears to be redundant
So far, this feature has only been seen on Golden Motor xxx Pie series, and obviously, any motor integrated with a hub torque/PAS sensor. I haven't find this option in the manual, or any official build template. Is it possible?
