throttle sensing conversions

[jdfnnl]

Would like to find conversion kits available with torque sensing bottom brackets which do not involve an LCD display.

The goal of the build is to always stay at a predefined assist level, have all the componentry housed in one place.

Controllers that natively understand/incorporate a throttle signal from a torque sensor are all proprietary?

I recommend talking to Grin Tech in Vancouver, from what I gather from reading their website the Grinfineon and Phaserunner controllers require you plug in a V3 Cycle Analyst display to operate torque sensing PAS and a throttle. Grinfineon and Baserunner controllers can operate without the CA display, Baserunner may require you to wire in an on/off switch, but in this setup they support throttle input only not PAS.

The German Pendix mid-drive kit uses a bottom bracket torque sensor and no display but does not have a throttle, has a wider Q factor pushing the left crank out which might feel odd pedalling, plus I gather it is not distributed in the US

According to this 4 year old webpage it may be possible to use Bafang BBS cadence sensor motors without the display by plugging in the programming cable, but I do not know then how you power the controller unless the battery on/off switch sends power to the controller, or if this trick works with TSDZ2 motors that do use a torque sensor plus throttle.
