Range Extender E-bike Battery and Charger E-Bike - Parts Rocky Mountain Bike Rocky Mountain is a Canadian producer of electric and muscle bicycles, at the top of the market in its sector. Present since the dawn of the "discovery" of mountain biking, rocky mountain has played a fundamental role in the development of geometry and mechanics. In 1992, he immediately won a world championship with Alison Sidor in the female elite category. From there begins a great string of successes, thanks also to Marie-Hélène Prémont, silver medalist at the Olympics in Athens and winner of the MTB world cup several times. The search for innovation has led Rocky Mountain to juggle all disciplines, including gravity. Here too there is no lack of success, thanks to Sabrina Jonnier, an international champion. The range has also expanded thanks to e-bikes, which immediately gained great visibility thanks to the sinuous shapes and quality components.
