With the Inissio Pmax gravel e-bike, you’re perfectly equipped even off paved roads. The second-generation Inissio gives you additional support through a specially designed hub drive unit, which lets even inexperienced riders conquer longer distances. The drive unit by Ebikemotion impresses with its incredibly light weight. An additional highlight: the new lightweight carbon frame. It lets you mount wider tyres and offers plenty of mounting points for convenient accessories. Amazingly versatile and stunningly beautiful: The Inissio Pmax makes the hearts of gravel enthusiasts beat faster.


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! 



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! 


The Inissio Pmax gives you plenty of options for upgrades, which lets you turn the e-roadbike into your own personal roadbike! If you need more power for longer rides, you can mount a range extender at the bottle cage position and increase the battery capacity by up to 670 Wh. We’ve also got great news for bike travellers and commuters: The gravel e-bike is available with matching mudguards, a rear rack and light system by Busch & Müller.
