The contemporary pearl white BMW cruise bike 2009 is designed with hydro formed frame. Normally used by car makers, the hydro forming process utilizes a high-pressure injection of emulsion of hot water and oil into an aluminium tube, causing it to expand until it matches the mould. The resulting frames are lighter and more durable than conventional bike frames. BMW equips its 2009 cruise bike with aluminum front suspension system and 24-speed derailleur system with Shimano Alivio Rapid Fire shifters for the ultimate cruising enjoyment. Weighing around 31 lbs this bike comes with 18- or 20-inch frame.
