Zoceli Vysoko Steel High-Pivot Enduro Bike Hides Split Drive Inside, Without A Chainring

"So, instead of adding a long parallelogram chain path with an idler pulley on the outside, Zoceli broke it up and put half inside. By splitting the drive path into two separate chains, Zoceli creates a compact, clean design where the drivetrain is more protected, extra weight is centered in the frame, and both suspension and braking are unaffected by your weight on the pedals."

"While there's plenty of complexity inside to make it work, on the outside it's a clean setup. No chainring to crud up or bash on rocks. And more room to build burly links for stiff suspension, which are then also easier to access for cleaning and servicing. And the more complex primary drive is tucked inside, away from nasty weather and trail debris - connecting a custom BB spindle with eMTB cranks at the bottom to a drive sprocket centered on the high-pivot up top."

Zoceli's Vysoko is a high-pivot steel enduro bike that splits the drivetrain into two separate chains called Split Drive. The primary heavy-duty dual-row timing chain runs inside the frame, connecting hardened cogs on a custom BB spindle to an upper axle. The external secondary chain runs along the seatstay to drive the rear wheel, eliminating an exposed chainring and reducing exposure to mud and debris. The internal drive centralizes weight, protects complex components from weather, and allows room for burly suspension links that remain accessible for service. The design keeps suspension and braking performance unaffected by pedaling forces.
