X35+40 Nm, Rear-hub. A lightweight rear-hub system rated about 40 Nm, controlled by a top-tube iWoc button.
X2055 Nm, Rear-hub. The newer, more powerful rear-hub system rated up to 55 Nm and lighter than the X35.

Mahle, a large German automotive supplier, makes the X35 and X20 lightweight rear-hub e-bike systems (formerly ebikemotion) widely used on road and gravel e-bikes where a discreet, light system is preferred over a powerful mid-drive.

MAHLE GmbH is a German automotive parts manufacturer based in Stuttgart, Germany.

Mahle systems use a slim in-tube battery (about 236 Wh on the X35, larger on the X20) with an optional range-extender bottle. The battery is matched to the Mahle system and is not interchangeable with mid-drive packs.

Published drive units include X35+ (Rear-hub rated 40 Nm); X20 (Rear-hub rated 55 Nm).
