Fatboy Scrambler V3 Ultra — Rugged. Powerful. Built for the Long Way Around.

The FatBoy Scrambler V3 Ultra electric fat bike is the most capable version of Australia's most iconic fat-tyre e-bike. Everything that made the Scrambler legendary — its planted stance, two-up capability, and go-anywhere confidence — is back, but completely evolved. Smarter power. Custom suspension. Brakes built for punishment. This is the e-bike for riders who don't take the easy route.

⚡ FBX Intelligent Power Platform

The V3 Ultra runs Fatboy's new FBX power architecture, developed alongside Bafang. Unlike standard e-bikes, where the battery, motor, and controller operate as separate parts bolted together, FBX connects them into one unified intelligent ecosystem. The result is smoother power delivery, better efficiency across all nine assist levels, and a more responsive feel — especially under load.

Motor: 52V Bafang rear-hub, 500W continuous / 1,560W peak output.

Torque: 100 Nm.

Battery: 52V 20Ah Samsung lithium-ion (Ultra spec).

Charge time: 4–6 hours full charge.

Speed: Restricted to 25 km/h for public road use (EPAC compliant).

Assist modes: PAS 1–9 cadence sensing + twist throttle (private property only).

Industry-First Custom Suspension

Fatboy engineered the V3's front fork from their own tooling — the first of its kind for fat-tyre e-bikes. It's built specifically to match the weight and geometry of the Scrambler, not adapted from an off-the-shelf design.

Fully adjustable preload, compression, and rebound tuning front and rear.

Rear fully adjustable mono-shock.

Dial in your setup for smooth bike paths, rough coastal tracks, or anything in between.

Every braking component on the Scrambler V3 Ultra is purpose-built for Fatboy — not sourced off the shelf.

4-piston hydraulic callipers with metal sintered pads.

Custom-designed cooling fins to manage heat at speed.

Heavy-duty 203mm discs, 2.9mm thick (front and rear).

Fatboy moulded brake levers for confident control in all conditions.

Refined Ergonomics for All-Day Comfort

From the first sketch to the final ride, the V3 was designed around the rider. A lower-profile seat welcomes a wider range of body types, updated handlebars promote a natural, relaxed posture, and a refined crank ratio keeps high-speed pedalling smooth and effortless mile after mile.
