A lowrider bicycle is a highly customized bicycle with styling inspired by lowrider cars. These bikes often feature a long, curved banana seat with a sissy bar and very tall upward-swept ape hanger handlebars. A lot of chrome, velvet, and overspoked wheels are common accessories to these custom bicycles. These bikes are typically a highly individualized creation. Despite the fact that these bikes originated within the poverty of the barrio, lowrider bikes can be expensive.
