Who is this for?

Best suited to

Riders who want Earth's 100Nm mid-drive in a 27.5-inch hardtail for paths, gravel and light trails.

Standout strength

100Nm of mid-drive torque with Schwalbe Smart Sam tyres and a claimed 50 to 100km range from 600Wh.

Check before buying: Confirm the frame size and the 25 km/h on-road setting at purchase.
