Overview
Quanbu's 20 inch unicycle in blue, built on the same manganese steel fork and adjustable seat clamp as the brand's other outdoor unicycles. Rated to roughly 200 kg (440 lb) for teen and adult riders.
This is the blue colorway of the 20 inch wheel in Quanbu's Outdoor Fitness line, which the brand also sells in 16 and 18 inch sizes and other finishes. The attribute bullets describe the same build across sizes: welded manganese steel fork, textured rubber pedals, and an aluminum alloy seat clamp. As with the other sizes in this line, no specific rider height chart is given, so match the wheel size to your experience using a general unicycle sizing reference.

Who it's for

Strengths and trade-offs
Drawn from this product's published specifications.
- Manganese steel fork rated to about 200 kg
- Adjustable aluminum alloy seat clamp
- Textured pedals for grip
- Blue finish as an alternative to black or yellow
- No rider height chart for this wheel size

Performance notes
Structurally this matches Quanbu's other 20 inch unicycles: a manganese steel fork welded to the frame for the 200 kg rating, rubber tread tires, and a raised pedal pattern for grip. The ride characteristics of a 20 inch wheel apply here too, faster and steadier than an 18 inch wheel but requiring more confidence to mount than a smaller size.
