## What is Sizz from hypersupp?

Sizz is a road bike sizing assistant that helps riders understand their body measurements and estimate practical frame geometry targets.

Enter key measurements such as height, inseam, arm length, torso length, shoulder width, and riding preference. Sizz then provides a clear visual reference for estimated Stack and Reach, helping you compare bike frames with more confidence.

Key features:
• Record complete body measurements for bike sizing
• Estimate target Stack and Reach values
• Visualize frame geometry with a clean bike sizing diagram
• Switch between English and Simplified Chinese
• Keep your profile saved locally on your device

Sizz is designed as a sizing reference tool for road bike selection. It does not replace a professional bike fit, medical advice, or final sizing guidance from a bike shop or manufacturer.
