Size chart and fit guide for 2026
QARSWA is an Amazon-direct mountain bike brand offering aluminum and high-carbon-steel hardtails and dual-suspension models at entry-level prices. They size by wheel diameter and rider height rather than published frame geometry. The 24" full-suspension model serves a wide 4'2"-6'0" range, while the 26"/27.5" aluminum hardtail covers riders 5'-6'3". Pick by wheel size: 24" for shorter teens and adults, 26" for average-height adults, 27.5" for taller riders.
