Is it for you?
Best suited to
Riders who want the cheapest way into an Earth hardtail for paths, gravel and light trails.
Standout strength
A hardtail with a 60Nm rear hub, a 500Wh battery and hydraulic brakes, at the entry price of Earth's trail range.
The main compromise
A rear-hub drive on a trail bike lacks the climbing feel of a mid-drive.
Consider something else if
You want mid-drive climbing torque, where the PRIME S Hardtail steps up.
Check before you buy
Confirm tyres and frame suit your terrain, and consider the dual-battery option.

How much does the Earth REX Hard-Tail weigh?
