    All this controllers are useless in this kind of application. You need torque mode and for that you also need position feedback for the commutation.

    I have no idea how strong 3D printed parts are. All I can say is that high speed corners and going over curbs puts the rig (and my hands) under a lot of stress while using 8 Nm.
    So far the wood/metal clamps I am using show no sign of fatigue.

    Yes, I thought about that too. After considering price/value for my needs I opted for the hoverboard motor. Yes, a bike motor might work too. It depends on your needs and the motor spec. The controller is capable of 8-50V and 30A(peak).

    Be aware, that in stall mode and with quick load changes (the controller pushes the wheel to the right, you are pushing into a left turn, then you hit the curbs which lets the controller alternate left/right very quickly) 30A are easily reached. I had to scale down from the possible 12 Nm (stall torque) to about 8 Nm in the above dynamic scenario to prevent activating over current protection. I am not sure how a higher W-rated motor will react in this situation.
