if you use single mounts on each long side of the bed you could fit around 6 bikes in the bed. i have fit 4 but i am sure you could fit atleast six plus geartheflavor said:If you had the rail cross bar you could mount two bike mounts on it near the end of the bed and have 4 bikes together. Two facing forward, two facing backwards. If you had them all facing the same direction the handlebars would probably all get in the way of each other.
