Mountain Bikes 27,5"

Mountain bikes with 27,5ʺ wheels are one of the most used bike types in the Czech Republic. Their sturdy frame is made for easier steering, while the wheels are especially suitable for difficult terrain.

If you tend to ride mostly off roads, a mountain bike is an ideal choice for you. For selected models, we offer a prolonged 10-year warranty and post-warranty service at our Prague, Brno, Ostrava and Vítkov stores.
