Is it for you?
Best suited to
Commuters who want the PRIME S mid-drive in a high-step trekking frame for longer, faster rides.
Standout strength
An 80Nm mid-drive with a 522Wh battery and hydraulic brakes, with an optional 1000Wh dual battery for touring.
The main compromise
The standard 522Wh battery is modest for long trekking rides without the dual-battery upgrade.
Consider something else if
You prefer a low step-through, where the PRIME S Trapeze shares the same drive.
Check before you buy
Decide between the standard and dual-battery versions based on your ride distances.

Common questions
How much does the Earth PRIME S Trekking cost in Australia?
The Earth PRIME S Trekking is listed at $3,290 (ride-away (incl GST)). eBikeFinder checks pricing against manufacturer and distributor information, and prices can change with sales and stock. This price was last checked on 2026-09-22.
Is the Earth PRIME S Trekking road legal in Australia?
Yes. The Earth PRIME S Trekking 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. Compliance is asserted by the brand rather than independently verified, so confirm the current spec with the seller.
What is the range of the Earth PRIME S Trekking?
The Earth PRIME S Trekking 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 Trekking have?
The Earth PRIME S Trekking 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 Trekking weigh?
The Earth PRIME S Trekking 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 Trekking 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.
