Riding easy on mountains, trails or simply further without extra effort. We have developed a model RUBY combining women requirements of mountain bike and modern technologies which combines all of these requirements together. We mainly paid attention to a lower seat for women theirs safety and comfort. It is also described by the universality of the mountain bike for urban and forest paths. The main advantage is the assistance of the electric motor when you pedaling up hill which you will really appreciate. From now on, every trip is possible, you just have to plan it well.
