  • Product Description

    Forward thinking design meets serious city performance. The Cannondale Bad Boy 4 is a hybrid sports bike that offers traffic slaying performance for the ultimate urban ride.

    With a complete redesign for 2017 the Bad Boy gets even badder. The OPI SmartForm frame features a 3D-forged head and down tube with smooth welds for a very clean look. Up front you get the ultra-stiff Lefty Rigid fork which offers agile point-and-shoot handling. Combined with high volume 650b tyres the Bad Boy is fast rolling and nimble handling with crazy cornering grip.

    Subtle reflective detailing on the top and down tubes add visibility without compromising style.

    Promax mechanical disc brakes deliver confident all-weather stopping while the Shimano Altus 3x9 speed drivetrain delivers a wide range of gears for taking on any gradient.

    Take the city by storm on the Cannondale Bad Boy 4.
