I didn’t know that BMW is making bikes, but these are looking very good. Actually BMW has some extraordinary bikes as well as prototypes.
BMW Cruise Bike costs about $800. The cruiser has a hydroformed aluminum frame. Hydroforming is a technique commonly used for shaping tubular structures like truck and car frames. A metal tube is placed inside a mold and then filled with pressurized oil until it conforms to the mold. The result is a strong, lightweight structure.
