About Thumpstar

Country of Origin: Australia (brand/design); manufacturing via Asia
Founder: Established by Australian off-road enthusiasts
Best Known For: Pit bikes, minis, and value off-roaders for training and play

Company History

Thumpstar built a global following with affordable, abuse-tolerant pit bikes and small off-roaders. The appeal is simple: tractable four-stroke singles, rebuildable suspension, and spares stocked by responsive distributors. Parents and track schools use them to teach clutch, braking, and body position; racers use them for cross-training. Iterative improvements to frames, hubs, and looms boosted durability, turning budget playbikes into trusted training tools.
