The Bomma is Mafia’s 29" cruiser-style BMX, in a mirror-finish chrome steel frame that stands out wherever it’s parked. It has big 29x2.5" Snakeskins tyres on black rims and spokes for a smooth, rolling ride, and a Shimano hydraulic disc brake gives confident stopping power. Graffiti-style Bomma graphics, a blue suede-look seat and a matching bar pad give it plenty of personality. Chunky black 3 peice cranks and grippy platform pedals complete a single-speed bike that’s as much fun cruising the streets as hitting the park.
