a bicycle with handlebars so wide you are almost forced to ride without any hands, big wheels to compensate for sandy grounds, and as little hardware on them as possible; come in any color you want and almost any shape; want a basket? you can have one; want THREE wheels? go for it, beach bikes got them too; hook on a surfboard and your in business; then drop in in the dunes and your ready to go
also...something a real beach bum would easily choose over a license and a bmw any day
"hey lets go surfing"
"sure let me get my keys..."
"R YA KIDDING?! yo im just taking my beach bike. peace."
