Gearing

Chainring ÷ rear sprocket

Lower ratios provide more mechanical advantage for climbing. Higher ratios turn the rear wheel farther with each crank revolution.

RPM

Estimate uses the published front tire 26×1.95 as a proxy, corroborated by the wheel size. Rear tire size is not published or verified. Approximate circumference; actual rollout varies with tire and pressure. Theoretical, not a maximum achievable speed.
