The Ultimate Beginner & Freestyle Unicycle: Qu-Ax 20" Luxus Trainer

Start your unicycling journey with the world’s most popular 20-inch trainer: the Qu-Ax 20" Luxus Unicycle. Designed and engineered by premier German manufacturer Qu-Ax, this bestselling unicycle combines rugged durability, smooth performance, and vibrant color customization. It is the gold standard for beginners, children, and entry-level freestyle riders looking to build balance and master new skills.

Dual-Seatpost Design: Grows with the Rider

One of the standout features of the Qu-Ax Luxus line is its dual-seatpost configuration. Every 20" trainer includes both a standard 350mm seatpost AND a second, shorter 200mm seatpost. This allows younger or shorter riders (minimum inside leg of 61 cm) to start riding immediately without parents having to cut down the saddle stem or purchase a replacement seatpost later as the rider grows!

German Engineering & Feature Highlights

• Flatcrown Freestyle Frame: Features a sturdy, powder-coated flatcrown steel fork with a two-piece dropout—providing a stable, flat surface for foot placement while practicing entry-level freestyle tricks.

• 36-Spoke Wheelset & Grippy Tires: Equipped with a durable 36-hole aluminum rim, a smooth square-taper hub, and a high-traction 20" x 1.95" (50-406 mm) tire for maximum stability and easy rolling over outdoor surfaces.

• Anti-Twist Seatpost & Quick-Release Clamp: The diamond-knurled steel seatpost prevents annoying saddle rotation during practice, while an aluminum quick-release lever allows fast, tool-free height adjustments.

• Ergonomic Safety Saddle: Features a well-cushioned, highly durable saddle with a built-in front handle for balance, replaceable protective bumpers, and wide, slip-safe two-component pedals.

• Vibrant Color Options: Available in a wide array of frame, rim, and tire colorways—including sky blue, pink, red, black, green, orange, white, and classic chrome.
