This setup reacts instantly to bumps, dips and rough surfaces, smoothing out the ride without killing feedback. Whether you are riding solo or with a passenger, the suspension stays balanced and composed.
FRONT: Adjustable rebound and compression to keep the front end controlled and responsive across uneven roads.
REAR: Fully adjustable compression, preload and rebound, paired with a custom shock bumper.
PASSWORD PROTECTED SETTINGS
Set a password to lock all display settings and keep everything exactly how you left it. Ideal for riders who do not want curious hands messing with their setup.
Once locked, key settings stay protected, including top speed and motor output. This is not a new add on or a limited feature. It has been standard across Fatfish e-bikes since December 2024.
We did not shout about it because, frankly, it felt like the most basic feature a bike should have. Some brands have just discovered how to do this (2026); we built it over a year ago. Ask an OG Fatfisher, and they'll tell you.
FLAT SEAT & SUPER FAT TYRES
Unlike all other dual suspension fat tyre ebikes on the market, our flat seat keeps you planted and comfortable. Fatfish seats are known for their comfort and textured finish.
Paired with 20x5.0 super fat tyres, grip comes from the ground up. More surface area. More stability. More confidence on the road.

BUILT WITHOUT TRADE OFFS
Step-through frames are often built for ease but rarely for performance. Many sacrifice power for comfort as though one person cannot want both.
We took our time with this release: refining the geometry, strengthening the frame, tuning the motor response, testing different types of suspension, designing multiple cargo racks, and multiple positions for you to customise the ride with add ons.
We finally cracked it. A step-through ebike that delivers on all fronts. That delivers the kind of power and control typically reserved for more aggressive builds and the comfort and convenience of a low entry frame.
V ERSATILITY.
PASSWORD PROTECTED SETTINGS
Set a password to lock all display settings. Ideal for riders who do not want curious hands messing with their setup.
Once locked, settings stay protected, including top speed and motor output, unless the password is entered to make changes. Not a new add on or a limited feature, but implemented as a base line.
Standard across Fatfish models since December 2024. Ask an OG Fatfisher, and they'll tell you.
i NTELLIGENCE.
DUAL SUSPENSION STEP THROUGH FRAME
The step-through geometry will allow you to sit naturally, so you stay relaxed.
Dual suspension absorbs what the road throws at you. An adjustable front fork manages impact up front, while two independent rear coils support the back end. This configuration maintains structural balance and keeps the ride stable whether you're riding solo or with a pillion rider.
C OMFORT.
LONG RIDES FOR A LONG TIME
High-torque custom Fatfish motor capable of handling strong acceleration, responsive torque and confident hill climbing.
Coupled with 200 mm double-thickness rotors for faster cooling and four piston hydraulic brakes to deliver precise braking power.
E NDURANCE.
