The Formula eF-1 Extended Range (2026) is an electric mountain bike designed for those who enjoy cross-country trails, touring, and long-distance commuting. Its heat-treated aluminum frame in a silver-black gradient with yellow accents provides a sturdy foundation, while the 21-inch XL size is specifically tailored for riders over 185 cm tall. Large 29-inch wheels and a front suspension fork help you maintain stability and comfort when navigating uneven terrain. Powering your journeys is a 500 W motor supported by a 48V battery with a 17.5Ah capacity. This high-capacity energy source allows you to travel up to 40% further than standard 12.5Ah models, making it a reliable choice for extended trips. To ensure safety during descents or sudden stops, the bike is equipped with mechanical disc brakes, giving you consistent control regardless of the distance you cover.
