The quick read

Is it for you?

Best suited to

Fire road and light singletrack riders who want a hardtail eMTB without full suspension weight or cost.

Standout strength

85Nm and 630Wh out of a hardtail is serious range and climbing power for the money.

The main compromise

No rear suspension, so rough descents will punish you more than the eOne-Forty or eOne-Sixty will.
