Footbike for beginners Getting more for less... In case you are just a footbiking beginner and you don't want to invest too much money in the new vehicle, then the footbike KOSTKA HILL FUN (max. weight 100 Kg) is a perfect choice for you! Just to be clear... This footbike is designed for both adults and teenagers and although it’s a top-notch quality, it’s still a bargain. We put maximum effort into the construction of this model in the same way as in case of all other footbikes KOSTKA - that’s why its design is well-made. A proud product from our workshops.
