For sporty riding
Pedal faster, pick up speed even faster: The Performance Line SX works at least as hard as you do. When riding in a sporty style with a high cadence, it supports you disproportionately to your performance with peaks of up to 600 watts of motor power. With its sensitive and reactive response behavior, it is ideal for all those who ride in sporty style with electric support and are looking for a training effect.
Lightness – almost natural
A reduced pedal resistance of more than 50 percent compared to the Performance Line CX, a narrower design of the cranks and an almost silent motor – the Performance Line SX convinces in many respects. Its direct but sensitive response conveys the feel of conventional cycling and enhances it with the ease and fun of eBiking.
Light, compact, agile
Around 4.4 lbs: The Performance Line SX is our lightest drive with the highest power density. Ride your eGravel bike dynamically into corners and carry your eUrban bike up to the fourth floor: The Performance Line SX reduces the total weight of your eBike, delivers greater agility and is ideal for fans of a sporty riding style. In addition, the compact drive unit disappears elegantly into the crank area of your eBike – so it looks like a conventional bike.
Multifaceted: sporty riding
You're looking for a challenge on the trail, on technically demanding passages and when riding uphill? Installed in light eMTBs, the Performance Line SX is the optimal piece of training equipment for you. But even if you're dreaming of long-distance adventures and don't yet know exactly which surfaces await you, the drive unit is ideally suited for powering eGravel bikes. You want to ride dynamically on the road with minimalist, agile eCity bikes? Here, too, the Performance Line SX is the right choice.
Optimal set-up for light, slim eBikes
