Freespin

The wheel spinning without a rider on it. Lift the wheel off the ground and let it spin - that’s freespin. Used for checking tire alignment, testing motor response, measuring max unloaded speed, and diagnosing noises.

When it matters

Diagnosing a rubbing tire or brake. Checking if the motor runs smoothly after maintenance. Transport mode - some wheels automatically freespin or lock when lifted via the lift sensor.

Freespin speed

The unloaded top speed of the motor at a given voltage. Higher than your actual riding speed because there’s no rider weight or wind resistance. Sometimes referenced when comparing wheel power.

555 take

Freespin is a diagnostic tool, not a riding metric. If someone quotes freespin speed as “top speed,” they’re measuring the wrong thing.
