E-GRIFN, E-ASTR or E-KANZO ADVENTURE: which e-gravel bike suits you best?
E-GRIFN (Mahle X20): a natural riding experience on- and off-road
Our engineers opted for the Mahle X20 drive unit, which delivers up to 250 watts of additional support and torque comparable to that of a 55 Nm mid-motor. Thanks to the torque sensor in the bottom bracket, the assistance always feels natural—like riding with a gentle tailwind. Every ride remains sporty and challenging.
The Mahle X20 offers three assistance levels, which our product managers fine-tuned together with Mahle specifically for the GRIFN. Switching between modes is easy via the satellite buttons on the handlebar or the top tube controller, which also displays battery status (350 Wh) and assistance level.
E-Grifn
Go further, longer, and higher!The first sporty e-bike from the brand. Thanks to the Mahle X20 drive unit, the E-Grifn feels very natural. You can choose from three levels of bike assistance. The Mahle X20 motor provides up to 250 watts of additional support with a torque comparable to that of a 55 newton meter mid-motor. We opted for the battery with the largest capacity (350Wh), and there is the possibility to expand it further with a 171Wh range extender.

The E-ASTR is equipped with the TQ HPR40 drive unit, providing up to 200 watts of additional power and a maximum torque of 40 Nm. Just enough to tackle obstacles more smoothly, without ever feeling like the bike is taking over. The motor (1.2 kg) and battery (1.42 kg, 290 Wh) are ultralight and elegantly integrated, keeping the total weight to a minimum.
Subtlety was key in the finishing details: there’s no display in the top tube, intentionally left clean. Instead, small LED lights in the handlebar cap indicate the selected assistance level. Both in looks and in ride feel, the E-ASTR remains faithful to the essence of a pure gravel bike.
E-ASTR
Our electric variant for the new standard in gravel performanceWith a sporty geometry and tire clearance up to 52 mm, the E-ASTR offers the familiar ride feel of a classic gravel bike—enhanced with a subtle boost. The lightweight, compact, and nearly silent TQ HPR40 motor provides natural support without compromising the cycling experience.
