You can choose your MTB size mainly based on your height. Most mountain bikes are labelled S / M / L, which are designed to suit different rider heights.

As a general guide:

S (Small): approx. 155–170 cm

M (Medium): approx. 168–180 cm

L (Large): approx. 178–190 cm

If you are between two sizes, your riding preference also matters — a smaller size feels more agile, while a larger size offers more stability.
If you’re unsure, feel free to tell us your height and we’ll be happy to recommend the best size for you.

No, there is no extra charge for assembling the bike. However, if you would like the bike to be shipped, it will need to be shipped in a box, and you will need to assemble it yourself.
