The right bike size = comfort + performance + safety
Choosing the right frame size is the basis of enjoyable riding. A frame that is too small causes discomfort and pain, one that is too big reduces your control over the bike. Use our guide to find your ideal size.
How to measure yourself
Body height
Stand against a wall without shoes. Measure from the floor to the top of your head.
Inside leg length
Stand with your feet shoulder-width apart. Measure from the floor to your crotch (with a book pressed between your legs).

Kids Kids' bikes
The size of kids' bikes is determined by wheel diameter. The child's height is what matters — age is only a guide.
| Wheel size | Orientačný vek | Výška postavy |
|---|---|---|
| 12" | 3–5 rokov | < 100 cm |
| 16" | 4–6 rokov | 95–115 cm |
| 20" | 5–8 rokov | 110–125 cm |
| 24" | 6–12 rokov | 125–150 cm |
| 26" | junior | 140–160 cm |
MTB Mountain bikes
The frame size depends on both the wheel diameter and your height. If you ride more aggressively, choose a smaller frame for better handling.

Useful tips
- Between two sizes? For a more comfortable ride (roads, touring) choose the larger frame. For a sporty riding style (MTB, racing) choose the smaller one.
- E-bikes are sized just like regular bikes — the motor does not change the frame size.
- Stem length and seatpost can be fine-tuned — but the right frame size is the foundation and nothing can replace it.
- A test ride je najlepší spôsob, ako si overiť správnu veľkosť. Bicykle označené „Dostupné v predajni“ si môžete prísť vyskúšať k nám na Podzámsku 31 — pozrite si, ktoré to sú.
