AVASTA Bike Size Chart
Official sizing guide for 2026
AVASTA is a value-tier Amazon-direct brand that prices entry-level mountain, hybrid, and kids' bikes between $160 and $280. Sizing is wheel-diameter and rider-height driven - adult MTBs come in 26" and 27.5" wheels, women's hybrids in 26" step-through and 700C step-over, and kids' bikes in 18", 20", and 24". Frames are sold in a single height per wheel size with adjustable saddle and handlebars rather than per-size geometry, so pick by wheel size and Amazon's published rider-height range.
