Bike sizing comes down to your height, inseam, and riding style—match them to the frame and contact points for a comfy, controlled ride.

Kids’ bike size hinges on height and inseam; match wheel size to those numbers for a safe, confident fit.

For a 5’5″ woman, start with a 52–54 cm road frame or Small–Medium (15–17 in) hybrid/MTB, then fine-tune using inseam and reach.

For a 6’2″ rider, start with XL frames (about 60–62cm road; 20–21″ MTB) and confirm with inseam and reach.

A typical 8-year-old fits a 20-inch kids’ bike, but inseam and height should steer the final choice.

For a 5’6″ woman, start with Medium frames: 52–54 cm road, 54–56 cm hybrid, and 16–17″ (M) mountain, then fine-tune by inseam and reach.

For a 5’3″ rider, start with XS–S frames: road 49–52 cm, hybrid 13–15″, and mountain 13–15″ with 27.5″ wheels.

For a 5’10” male, most riders fit a 56–58 cm road frame or a Medium/Large MTB or hybrid, fine-tuned by inseam and reach.

For a 5-foot woman, road 44–48 cm, hybrid 13–15 in, and mountain XS/S usually fit—confirm with standover, reach, and saddle height.

Most 10-year-olds match 24-inch wheels; confirm with a 24–28 in inseam and a safe standover gap.
