"Sicker than your average..." Biggie
Meet the Fatfish Biggie, the ultimate ride for those who want power, style, and endurance in one beast of an e-bike. Whether you’re tearing up the streets or cruising to your next adventure, the Biggie’s got your back with top-tier components and serious performance.
With a 48V 250W high-torque rear motor and a 20Ah Samsung battery, the Fatfish Biggie delivers up to 100 km on a single charge.
Built with a larger frame than the Fatfish OG, the Biggie is designed for taller riders who want extra control, stability, and handling.

Next-Level Stopping Power: Tektro Hydraulic Disc Brakes, featuring Motor
Safety Cut Off. This means you’re always in control, no matter the conditions.
Smooth Suspension: A 60mm front fork soaks up bumps for a cushy ride.
Tough & Ready: Built on a lightweight yet sturdy aluminium alloy frame, featuring marine-rated cables for easy servicing.
Commuter & Adventure-Ready: Puncture-resistant 20” x 4.0” tyres on one-piece alloy rims give you the perfect mix of grip and durability.
Smart Display & Controls: The centre-mounted C900 LCD shows speed, trip info, battery life, and more. The built-in horn, and USB charging make it city-proof.
Cargo-Friendly: A MIK-ready reinforced rear rack lets you slide cargo on and off effortlessly.
Max Load: Carry up to 160 kg, including gear, groceries, or whatever else you need.
With a 3-year frame warranty, 2 years on battery and motor, and 1 year on all other components, the Biggie isn’t just an e-bike, it’s an investment in next-level riding.
