Details
On the road, on gravel or on an easy trail – the gravel e-roadbike by Simplon boasts an impressive affinity for rough terrain thanks to a tyre clearance of up to 40 mm. But that’s not all! It’s also perfect for everyday use: With mudguards, a light system and a rear rack, the e-roadbike turns into a real all-in-one utility bike. For bike travellers, commuters or gravel racers, the carbon roadbike is an absolute must-have! What else does this e-roadbike by Simplon have to offer? Let’s find out!
Features
- High-profile tyres with up to 40 mm in width provide comfort, increased accident protection and lots of grip to be able to safely ride even on rough terrain.
- Almost invisible and super lightweight (at only 2 kg): the hub-drive motor by Ebikemotion between the sprocket cluster and disc. The drive unit reaches a torque of up to 40 Nm and supports the rider on the mountain at a speed of up to 26 km/h. If you ride without support, you hardly notice the drive unit. With hardly any resistance, it allows for efficient riding on flat terrain.
- A 250-Wh battery is seamlessly and beautifully integrated into the down tube. The charging socket is easy to reach because of its location between the down tube and the seat tube. A range extender, which can be connected right at the charging socket, offers you the possibility to double your range.
- Control – but safe! The control unit sits perfectly integrated in the top tube. Via button and colour-spectrum LED display, you can select three support levels. The display also shows you the battery capacity. A display on the steerer thus becomes obsolete.

Technology
The innovative technology features by Simplon were used on the Inissio Pmax as well, of course. Here are the high-end highlights of the e-roadbike: Say goodbye to tangled cables and hello to a clean look: with the internal cable routing through the headset and the optional steerer/stem unit! The gravel e-roadbike is designed to conquer long distances. To make the riding experience even more relaxed and comfortable, Simplon uses its tried and tested Comfort Concept. Top tube, seat stays and seat tube constitute a perfect unit at the point where they merge. The Raptor Dropout technology – rear-facing dropouts – gives the bike higher vertical flex and more comfort at the fork. A definite bonus in rough terrain!
