gearless
Without toothed wheels
Gearless describes something without gears—the toothed wheels that transmit motion in machinery.
A gearless elevator uses a direct-drive motor rather than a geared system.
A gearless bicycle has a single fixed ratio, offering simplicity at the cost of versatility.
The term appears in engineering contexts where eliminating gears reduces maintenance or improves efficiency.
