Couldn’t find a thread specifically discussing this…
Is there a rule-of-thumb ratio between front and rear current that is optimal for accelerating and braking to maximize efficiency and traction? For example:
Accelerating: 70% rear and 30% front
Braking: 30% rear and 70% front
Building a primarily on-road 4wd board and thought I would appreciate the forum’s wisdom. Thanks in advance.

You basically want to tune it so that the front doesn’t spin on a hard launch, and the rear doesn’t spin on hard braking. Assuming good posture for both.
On my board I prefer about 25% front 75% rear split for acceleration and 70% front 30% rear for braking, but what works best for me might not be the ideal setting for you.
Also worth noting that I have a ton of torque compared to most setups, even compared to many 4WDs - the more torque you have in total, the more bias you want generally speaking.

Thanks a lot. Sounds like a good spot to start. Makes sense that the harder you are accelerating or decelerating, the more bias you need. Car forums seem to discuss more conservative torque split like 45:55 or 40:60, but cars have lower center of gravity for wheelbase (compared to standing rider on a skateboard) and as a result more even traction between front and rear.
