AN ICON EVOLVED AND ROAD-LEGAL

2 Tough. 2 Sharp. 2 Clean.

Some brands like to claim they are the OG of Fat Tyre e-bikes. At Fatfish, we never had to claim it. We built it. And now, we've taken it further. That's a fat W.

 

After riding the Fatfish OG for thousands of kilometres, listening to every customer review, and pushing through real-world tests, our team knew what was next. We took everything that made the OG legendary and created the only G that matters in fat tyre e-bikes.

Introducing the OG 2.0: twice the attitude, twice the performance, and still the g.

What makes the OG 2.0 different from the OG?

 

Improved Steering Stability. The OG 2.0 feels more planted and controlled, giving you confidence at any speed.

Lighter, Easier Handling. A shorter wheelbase and refined geometry enhance urban commuting and navigation through tight spaces.

Smoother Ride Quality. The upgraded frame design delivers a more comfortable and responsive experience on every ride.

 

OG 2.0 vs. Biggie: Which Fat Tyre E-Bike Fits You Best?

 

OG 2.0: Shorter wheelbase. Quicker handling. Perfect for riders under 175 cm who want an agile, connected ride.

Biggie: Longer wheelbase. Maximum stability. Perfect for riders over 175 cm who want smooth, confident rides.
