The Garage

Youth bikes by seat height

Every bike in the Garage with a stock seat height under 900 mm, lowest first. 2 of the 6 heights are read off an owner’s manual page; the rest come from the maker’s spec sheet and say so.

Seat heights

Stand in riding boots, back to a wall, and measure from the floor to the crotch.

A seat sits lower once a rider is on it, by an amount that depends on the rider and the suspension setup, so this list is a starting point for a sit-on test, not a size chart. The seat height finder lines these numbers up against a rider’s inseam.

State rules for young riders

Each state’s age and supervision rule for young riders of off-road vehicles, restated from the official text on its E-Moto Hub page. It is not legal advice, and land managers and tracks can add their own rules.

  • Arizona

    The operating rules in § 28-1174 (ride only on open roads, trails, routes and areas, never recklessly, and without off-route damage) bind anyone who lets a minor under 12 ride. If a minor under 12 breaks them, the citation is issued to the parent or legal guardian, not the child. The section sets no minimum age.
