An engine model (20) for use on a children's ride-on vehicle (10). The engin e model (20) includes a pivotal portion (50) configured to pivot about a pivot axis, a vibration source (58) connected to the pivota l portion (50) to thereby vibrate the pivotal portion (50) at an amplitude, and an adjustment mechanism (118) for selectively controlling the amplitude. A dampening structure (110, 112, 114) may be provided to dampen the vibration of the pivotal portion.
