For nearly 40 years, Mongoose has been stuck in mud, on trails and slopes. Mongoose was established in a garage in Southern California in 1984. It has always been an offensive brand with products that exceed the limits of what a rider can do. This steel-framed mountain bike with super-full terrain knob tires can easily conquer any off-road route. The 7-speed transmission makes it easier to climb the mountain and change gears when riding. This wireless headset is adjustable to suit riders of different heights. In order to increase speed and performance, strong light alloy edges can reduce weight. Use the beach cruiser pedals to ride comfortably and ensure the safety of the front and rear brakes. This bike is ready to be assembled for shipment. Sizes for adult riders: 5 feet, 6 inches to 6 feet tall.
