Is it for you?
Best suited to
Taller riders who want a 29-inch mid-drive hardtail for gravel, fire roads and light trails from an Australian brand.
Standout strength
A 100Nm mid-drive and 29-inch wheels roll over rough ground well, with a dual battery upgrade available.
The main compromise
Entry level Altus gearing and a 100mm fork limit it to light trail riding, and nominal wattage is not published.
Consider something else if
You prefer the nimbler feel of smaller wheels, where the T-REX 650B SP shares the same drive.
Check before you buy
Confirm frame size for your height and that the bike is set to the 25 km/h on-road configuration.

What is the range of the Earth T-REX 29SP Hard Tail?
The Earth T-REX 29SP Hard Tail has a claimed range of 40 to 70 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 29SP Hard Tail have?
The Earth T-REX 29SP Hard Tail uses a EARTH ATM SP 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 29SP Hard Tail weigh?
The Earth T-REX 29SP Hard Tail 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.
