Here's proof they DO make bikes big enough for Shaquille O'Neal!!
The NBA Hall of Famer felt the urge to go on a bike ride during his vacation in Nassau, Bahamas on Wednesday ... so he ducked into a local shop and asked for the biggest 2-wheeler they got.
The shop delivered -- and Diesel was so happy, the 7'1" giant took the whip out for a quick cruise around the neighborhood ... while wearing some amazing floral-pattern shorts!
As we've previously reported ... Shaq loves his 2-wheelers, but usually has to get them customized to fit his gigantic body size.
By the way, props to whoever made this bike -- witnesses at the shop tell us the bike survived all 300 pounds (more?) without a problem!
