Nannies

Dismissive slang for firmware-level safety restrictions. Speed caps, aggressive tiltback, early alarms, current limiting - the manufacturer’s way of saying “we’d rather annoy you than replace your board.”

The tension

Riders want maximum performance. Manufacturers want wheels that don’t burn their electronics. Conservative firmware protects the MOSFETs and the board at the cost of available power. Some riders see this as the manufacturer prioritizing component survival over rider safety - if the firmware cuts power to save the board, the rider hits the ground.

King Song vs Begode philosophy

This debate plays out differently by brand. King Song historically favors stricter limits. Begode gives more power access but less protection. Neither approach is objectively correct - it’s a trade-off between freedom and guardrails.

555 take

Nannies exist because electronics have hard limits. You can resent them or understand them. The smart move is to ride within the limits and appreciate that your board isn’t designed to sacrifice itself (and you) for one more km/h of speed.
