Heavy Cargo Quadricycle w/Bafang BBSHD Mid-Mount Motor and rear GrinTech All Axle (reverse) Controller Integration

[Cynthia Priddy]

Integrating the Bafang MidMount Motor with GrinTech All-Axle e-hub motor. Told that the Cycle Analyst can be used to integrate both motors and controllers with the Grin Tech cycle analyst controlling both motors? Anyone with any experience?

Want Mid-motor for power and Grin Tech e-hub motor for reverse function. This is a heavy cargo bike 1000lbs. capacity.

It sounds like the two motors will not be used together, but one for forward and the other for reverse. For that, the CA seems to be overkill or not needed (the CA does switch from forward to reverse. A simple switch, directing the throttle signal wire between the two controllers (mid or hub controller) should work for 100th the cost.

PS. The all axle is a direct drive motor. It’s going to create a lot of drag when not powered, and the drag will increase with speed, so not sure that’s the best solution.

Grin has just released firmware for it's Phaserunner/Baserunner controller that offers torque sensing and reverse without a Cycle Analyst.

In addition, Grin offers a trickle setting that provides just enough power to over come any magnet cogging - they call it virtual freewheeling. They also that in most cases, the power recovered from Regen breaking exceeds the power used for the virtual freewheeling so it is not of concern.

Probably necessary to be able to fine tune the virtual freewheeling if it’s a quad, and only one of the 4 wheels is a dd hub motor to keep it from pulling to one side. Maybe I’m not picturing the setup correctly.
