Fatfish Biggie 20AH

The Fatfish Biggie 20Ah is built for riders who demand serious power, endurance, and versatility from their electric bike. Whether you’re commuting daily, carrying cargo, or heading off the beaten path, the Biggie delivers confident performance with a rugged yet refined design that turns heads wherever it goes.

 

At the heart of the Biggie is a high-torque 48V rear hub motor, locked at 500W for legal road use and unlockable to 750W with a peak output of 1080W for off-road riding. Paired with Shimano 7-speed gearing, this setup delivers smooth acceleration, hill-crushing torque, and effortless cruising across varied terrain.

 

Range anxiety is eliminated thanks to the massive 960Wh (20Ah) Samsung-cell battery, capable of delivering up to 200km in Eco mode. The battery is engineered with superior weatherproofing and secured with an integrated safety strap, making it reliable for long rides and daily use in changing conditions.

 

Comfort, safety, and practicality are built in. Fat 20” x 4.0” puncture-resistant tyres, a 60mm suspension fork with lockout, and Kamros hydraulic disc brakes with motor cut-off provide control and confidence on every ride. Integrated lights, indicators, horn, USB charging, and a reinforced MIK-ready rear rack make the Biggie a true all-rounder — powerful, smart, and ready for anything.
