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.

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.
