Smart performance. Smooth resistance. Premium design.

The MERACH MR-S39 Black Knight Turbo is a premium smart indoor cycling bike designed for smooth, responsive and immersive home training.

Its advanced magnetic resistance system provides quiet, precise resistance changes, while the self-generating design allows the bike to operate without relying on a permanent wall outlet. MERACH positions the S39 Turbo as one of its more advanced indoor cycling models, combining intelligent resistance technology with a heavy-duty flywheel system. 

The bike features smart resistance adjustment, allowing training intensity to respond more naturally during connected workouts. It also incorporates optical heart-rate monitoring and app-connected training functionality for a more interactive riding experience. 

A large padded saddle, multi-position handlebars, device holder and stable frame make the MR-S39 comfortable for everything from steady-state cardio to higher-intensity indoor cycling sessions.
