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.
