The Mountain Stand Up Bike takes stand up cyclists where they’ve never gone before: off-road. From dirt trails to urban landscapes, this cardio-chameleon allows riders of all levels to customize where they GO. Accept any challenge with knobby, 27.5” tires, smooth, 100mm front suspension, and high-performance disc brakes. New adventures await with the comfortable, fun and hyper-efficient workout experience you expect from ElliptiGO bikes. Whatever your mountain, climb it with the MSUB.
