The Fatfish OG 2.0 is the next generation of our iconic fat-tyre e-bike, engineered for riders who want agility, comfort, and performance in every ride.
Built from thousands of kilometres of real-world testing and rider feedback, the OG 2.0 takes everything that made the original a legend and pushes it further.
Designed with a shorter wheelbase and refined geometry, the OG 2.0 delivers lighter handling, improved steering stability, and a smoother ride across all terrains. Perfect for urban commuters or riders under 175 cm, this model balances power and precision to create an agile, confident experience on the road.
Powered by a Fatfish 48V 250W high-torque rear motor and a long-range 960Wh Samsung battery, the OG 2.0 is built for endurance. Expect up to 100 km in eco mode, hydraulic disc braking for superior control, and a robust aluminium frame capable of carrying up to 160 kg.
Premium features include a Shimano 7-speed drivetrain, an adjustable suspension fork, integrated front and rear LED lighting, a MIK-ready rear rack, marine-rated cables, and a center-mounted C900 LCD display with five levels of pedal assist.
The Fatfish OG 2.0 is not just another fat-tyre e-bike; it is the only G that matters. Agile, durable, and rider-focused, it’s built to keep you moving with style and confidence.
What's included?
Battery charger, MIK ready rear rack, 2 keys for the battery, bottle cage, front & rear Light, built in horn, foot pegs, and pedals.
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.
