The Wattbike Atom (Next Generation) is not a spin bike, although it can be used to follow online spin classes (such as on the Peloton app). If you are used to riding a spin bike it is likely to take a couple of rides to adapt to the feel of the Atom. For example, it may take some time to master riding out of the saddle. The main cause of the difference in ride-feel of the Wattbike Atom and a spin bike is that a spin bike has a fixed-wheel-like style where the turning of the flywheel keeps the pedals moving even if you are not putting pressure on the pedals (never suddenly stop pedalling on a spin bike), whereas, the Wattbike Atom rides more like a classic geared road bike, meaning any dead-spots in your pedalling style are noticeable.
