Biggie's Bringin' the heat- it's Bigger, Better and Badass

With a 48V 500W high-torque rear motor and a 20Ah Samsung battery, the Fatfish Biggie delivers up to 100 km on a single charge in eco mode.

Built with a larger frame than the Fatfish OG, the Biggie is designed for taller riders who want extra control, stability, and handling.

The little things that make the Biggie a big deal-

Riding should feel just as good as it looks.

✔ MIK-ready rear rack lets you carry your gear with ease.

✔ 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.

Comfort Meets Innovation

✅ Clean cable management keeps things sleek and tidy.

✅ 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.

While the OG still offers a comfortable ride, the Biggie takes it up a notch, giving taller riders more room to move and a more planted feel on the road.
