Determine the optimal frame size for your youth bike
1. Measure step length
Please measure your inside leg length from the sole (without shoes) to the crotch.
Depending on body size and sex, the crotch length of an adult is between about 65 cm and 95 cm.
2. Calculate the frame size
Enter your step length in cm:
If the calculated value is between two frame sizes
- For a more agile, sporty driving experience choose the smaller bike
- For a more quiet, touring-oriented experience choose the larger bike
Don't have a tape measure?
Use this table and take your body size as a clue.
| Your height in cm | Recommended Frame Size in cm (inches) |
| 145-155 cm | 33-35 cm (13"-14" inches) |
| 155-165 cm | 35-38 cm (14"-15" inches) |
| 165-170 cm | 38-41 cm (15"-16" inches) |
| 170-175 cm | 41-43 cm (16"-17" inches) |
| 175-180 cm | 43-46 cm (17"-18" inches) |
| 180-185 cm | 46-49 cm (18"-19,5" inches) |
| 185-190 cm | 49-53 cm (19,5"-21" inches) |
Please note:
These recommendations are only a guidance. The ratio of leg length and upper body length can vary greatly.
