Bike Size Guide
Choosing the right bike size is crucial for comfort, safety, and riding enjoyment.
The right frame size is one of the most important factors when choosing a bike. A properly fitting bike not only increases riding comfort but also protects your back and joints, reduces fatigue, and improves control and efficiency.
Height & Recommended Frame Size
| Height | Mountain Bike | City / Trekking | Road Bike |
|---|---|---|---|
| 135–145 cm | 33–36 cm | 38–42 cm | 46–48 cm |
| 145–155 cm | 36–40 cm | 42–46 cm | 48–50 cm |
| 155–165 cm | 40–44 cm | 46–50 cm | 50–52 cm |
| 165–175 cm | 44–48 cm | 50–54 cm | 52–54 cm |
| 175–185 cm | 48–52 cm | 54–58 cm | 56–58 cm |
| 185–195 cm | 52–56 cm | 58–62 cm | 58–60 cm |
| 195+ cm | 56+ cm | 62+ cm | 60+ cm |
These values are guidelines. Body proportions and riding style may affect the ideal size.
What is Frame Size?
Frame size refers to the vertical distance between the center of the bottom bracket and the top of the seat tube.
- Measured in centimeters (cm) or inches
- 1 inch = 2.54 cm
- Determines ergonomics, seat height, and riding stability
How to Measure Your Inseam
The ideal frame size is usually calculated based on your inseam (inside leg length).
Stand barefoot upright against a wall
Place a book or level between your legs (like a saddle)
Measure the distance from the floor to the top of the book
Calculation by Bike Type
Mountain Bike
Inseam × 0.225 = inches
Example: 84 cm × 0,225 ≈ 19"
Road Bike
Inseam × 0.665 = cm
Example: 84 cm × 0,665 ≈ 56 cm
City / Trekking
Inseam × 0.66 = cm
Factor between 0.64 and 0.66
Calculate Correct Saddle Height
The correct saddle height is just as important as frame size for optimal riding comfort.
Inseam × 0.885 = Saddle Height
Example: 84 cm × 0,885 ≈ 74 cm
Important Tip
When in doubt, choose the smaller size – a bike that's too big is harder to control. We recommend a test ride when possible.
