Is it for you?
Best suited to
Riders who want the simple Stubbie fat-tyre cruiser with a step-over frame for beach paths, errands and short commutes.
Standout strength
A Samsung-cell 48V 15Ah battery, 65Nm Bafang hub and integrated rear rack at one of the lowest full-size AMPD prices.
The main compromise
No suspension, and at 37.5kg it is heavy to lift.
Consider something else if
You want an easier low step, where the Stubbie-S S3 is the same bike with a step-through frame, or you ride rough tracks and want the suspension fork of the Stubbie PRO.
Check before you buy
Order the 250W Road Compliant configuration for public roads; AMPD says it cannot be changed later.

Is the AMPD Bros Stubbie S3 road legal in Australia?
Yes. The AMPD Bros Stubbie S3 is a 250W pedal-assist e-bike that stops assisting at 25 km/h, which meets the road-legal e-bike standard in every Australian state. Its throttle is limited to 6 km/h, which is the walk-assist limit allowed on a road-legal e-bike.

What is the range of the AMPD Bros Stubbie S3?
The AMPD Bros Stubbie S3 has a claimed range of about 60 km from its 720Wh battery. Real-world range is usually lower than the claim, since it depends on assist level, rider weight, terrain and wind.

How much does the AMPD Bros Stubbie S3 weigh?
The AMPD Bros Stubbie S3 weighs about 37.5 kg. That matters if you need to lift it onto a car rack, carry it up stairs, or store it, since e-bikes are heavier than regular bikes because of the motor and battery.
Who sells and backs the AMPD Bros Stubbie S3 in Australia?
The AMPD Bros range is distributed in Australia by AMPD Bros (Gold Coast, QLD). It comes with a 2 years frame, 2 years motor and battery warranty. Buying from a brand with real Australian support matters most when something needs a warranty claim or a service.
