Is it for you?
Best suited to
Comfort-first city riders who want a low step-through with a genuine mid-drive motor and a full commuter fit-out from an established Australian brand.
Standout strength
An 80Nm mid-drive and a 522Wh Samsung battery on a step-through commuter, with hydraulic brakes, from a long-running Australian brand.
The main compromise
Mid-tier drivetrain and a modest 522Wh battery limit long-range touring without the dual-battery option.
Consider something else if
You want a rear-hub bike for less, where Earth's own REX line is the budget option.
Check before you buy
Confirm the frame size and whether you want the optional second battery for longer rides.

Is the Earth PRIME S Trapeze road legal in Australia?

What is the range of the Earth PRIME S Trapeze?
The Earth PRIME S Trapeze has a claimed range of 40 to 60 km from its 522Wh battery. Real-world range is usually lower than the claim, since it depends on assist level, rider weight, terrain and wind.
What motor does the Earth PRIME S Trapeze have?
The Earth PRIME S Trapeze uses a EARTH 80Nm mid-drive motor, in a mid-drive position, producing 80Nm of torque. Mid-drive motors climb hills better because they work through the bike's gears.
How much does the Earth PRIME S Trapeze weigh?
The Earth PRIME S Trapeze weighs about 27 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 Earth PRIME S Trapeze in Australia?
The Earth range is distributed in Australia by Earth Electric Bikes. Buying from a brand with real Australian support matters most when something needs a warranty claim or a service.
