The Nebula XX is the top of the Nebula line, and it is built around one idea: as little maintenance as possible. The Enviolo Trekking hub gives you stepless gearing — no derailleur, no fixed gears to step through, and you can change ratio while standing still. The frame is aluminium with 28-inch wheels, and the fork is an SR Suntour NVX32.

The tyres are what set it apart on the road: Schwalbe Big Apple 700C × 55C. That is a wide, high-volume tyre that soaks up brick, cobbles and potholes without the weight of a fat bike.

Same Bosch Performance Line PX drive unit and 600 Wh PowerTube battery as the Nebula X, same Purion 200 display, same Shimano MT200 hydraulic disc brakes.

It suits riders who would rather ride than maintain.

What it is not: the Enviolo hub and the Big Apple tyres are chosen for paved and brick surfaces. This is not an off-road bike.
