T-REX SP Trekking
Pedal-assist, rated to 250W, assist cuts at 25 km/h. Declared by the brand; declaration not independently sighted.
Is it for you?
Best suited to
Riders who want Earth's strongest mid-drive (100Nm) in a trekking frame with a 600Wh battery and an optional second pack.
Standout strength
A 100Nm ATM SP mid-drive with Schwalbe tyres and a 600Wh battery, expandable with a second pack.
The main compromise
Earth publishes torque but not nominal wattage for the T-REX drive, and a dealer speed-unlock has been reported, so the on-road configuration should be confirmed.
Consider something else if
You need a clearly documented nominal wattage, since Earth does not publish it for the T-REX, or you want a lower price from the PRIME S line.
Check before you buy
Ask Earth or the dealer to confirm the motor's nominal wattage and that the bike is set to the 25 km/h on-road configuration.

Common questions
How much does the Earth T-REX SP Trekking cost in Australia?
The Earth T-REX SP Trekking is listed at $3,790 (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 T-REX SP Trekking road legal in Australia?
Yes. The Earth T-REX SP 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 T-REX SP Trekking?
The Earth T-REX SP Trekking has a claimed range of 50 to 100 km from its 600Wh 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 T-REX SP Trekking have?
The Earth T-REX SP Trekking uses a EARTH ATM SP 48V mid-drive motor, in a mid-drive position, producing 100Nm of torque. Mid-drive motors climb hills better because they work through the bike's gears.
How much does the Earth T-REX SP Trekking weigh?
The Earth T-REX SP Trekking weighs about 26 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 T-REX SP 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.
