Why Amp'd Bros
Amp'd Bros builds capable, well-specced fat-tyre e-bikes designed for Australian riders. The range covers stable, comfortable fat-tyre platforms with quality components — hydraulic disc brakes, suspension and throttle-equipped models — across step-through and step-over frames to suit different riders. There's even a kids' model, the Lil' Rippa, so younger riders aren't left out. It's a brand that delivers genuine capability and a confident, planted ride.
The Amp'd Bros Range
-
Ace S Plus: step-through frame — easy on-off, comfortable, a great all-round commuter and cruiser.
-
Ace X Plus / Ace X Pro Dual: step-over frames with more performance, the Pro Dual adding dual suspension for the smoothest ride over rough ground.
-
Stubbie Original S2: the compact, characterful cruiser — fat tyres and fun in a smaller package.
-
Lil' Rippa: a kids' electric bike so younger riders can join in safely.
-
Accessories & spares: cargo racks, baskets, mirrors, throttles, phone mounts and more.

How to Choose Your Amp'd Bros
-
Frame style: step-through (easy on-off, the Ace S) vs step-over (sportier, the Ace X) — comes down to comfort and preference.
-
Intended use: on-road commuting vs off-road and private-land fun drives which model and power level is right (and its legal status).
-
Motor power: determines hill performance and road-legal status in Australia — we'll match it to your use.
-
Suspension & brakes: dual suspension (Pro Dual) and hydraulic brakes add comfort and stopping power on a capable fat-tyre bike.
Australian Road Rules
In Australia an e-bike is only road-legal as a bicycle if it meets specific power and control limits (generally 250W, pedal-assist). The Amp'd Bros range includes road-legal-compliant models as well as higher-powered models intended for off-road and private-land use. Which is right depends on where and how you'll ride, and the rules vary by state and do change. Not sure which Amp'd Bros is road-legal for your situation? Talk to us before you buy — we'll make sure you get the right one.
