Built with a larger frame than the Fatfish OG, the Biggie is designed for taller riders who want extra control, stability, and handling. Improved seat grip and tougher seat cover for a more secure and comfy ride. Turn signal indicators to make sure you're seen in traffic. Built-in horn for that extra safety edge. Fat 20x4.0” puncture-resistant tyres that can handle whatever the road throws at you. Three ride modes (Eco, Normal, and Power) let you control how much boost you need. USB charging means your devices stay powered up on the go. A separate light control panel gives you easy access to headlights and turn signals. Walk mode makes manoeuvring a breeze when off the bike. A feature-packed LCD display keeps you informed with speed, battery life, and ride stats. "Sicker than your average." - B.I.
