Say hello to your new ride-or-die—the Fatfish Step Thru. With a killer 48V 21Ah Samsung battery and bold-as-hell style, this beast is here to crush hills, own the streets, and leave everyone in your dust.
Power, Unleashed: Rock a Bafang 250W motor (unlock to 750W for private property). With 80 Nm of torque, you’ll laugh at hills and glide over rough terrain. And with the massive 48V 21Ah battery, you’ve got up to 80+ km of pedal-assist range to go wherever the adventure takes you.
Shimano 8-speed gears and 100mm inverted suspension keep things smooth even when the road gets rough. From city commutes to weekend trails, this ride can do it all.
The 20x4.0" fat tyres grip like a boss, letting you shred through streets, dirt paths, and everything in between.
Matte black fenders, motorcycle-style handlebars, and a tough aluminium frame—this bike doesn’t just ride bold; it looks bold.
The extra-long seat means you can roll solo or bring a mate. And with Tektro hydraulic brakes, you’re always in control no matter how fast you’re going.
The backlit LCD display has all your stats—speed, battery, distance, you name it. Plus, the LED lights make sure you stay seen day or night.
The Fatfish Step Through isn’t just a bike—it’s a statement. Whether you’re hitting the streets, tearing up trails, or just showing everyone what’s up, this ride makes every journey legendary.
Step Thru, Stand Out- Built for the Bold.
Bigger, better and bolder. Built to last and turn heads, the Fatfish Step Thru takes everything you love about the original and kicks it up a notch.
Grip the Streets, Own the Trails
Climb hills, shred the streets, or own the trails with zero effort. With a Shimano 8-speed drivetrain, front suspension, and 15° hill-climb power, nothing's off-limits. The extra-long seat means you can roll with a mate, cruising in comfort all the way!
