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.

 

DUAL SUSPENSION WITH CUSTOM SHOCK BUMPER

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.
