The Muga utilizes a geometry concept borrowed from modern mountain bikes but adapted for touring and utility. A 66.5-degree head tube angle provides high-speed stability and predictable steering, keeping the front wheel tracking straight when the bike is heavily loaded. This is paired with a steep 76-degree seat tube angle across all sizes, which centers the rider over the bottom bracket. This upright, forward-biased seated position improves pedaling efficiency and prevents the front wheel from wandering on steep climbs.
To maintain maneuverability, Orbea uses relatively compact 466.5mm chainstays. This keeps the rear wheel tucked in, allowing the bike to navigate tight urban corners more easily than a traditional long-wheelbase cargo bike. A 36mm bottom bracket drop keeps the center of gravity low, aiding balance at low speeds.
Fit is highly customizable through a proprietary four-position adjustable cockpit, allowing riders to toggle between a relaxed, upright stance for city traffic and a lower, stretched-out posture for longer trekking routes. Additionally, every frame size comes standard with a dropper seatpost, enabling riders to quickly lower their saddle for stable footing at stoplights or a lower center of gravity on descents.
