When we developed the 300R, we had a simple goal: create the best value for an entry-level Fitness bike. Here is how we did it: make it stout, quiet, smooth, and maintenance free. Back it with the best warranty support in the industry. More: give the console the most meaningful feedback the rider needs to build Fitness. Make it manual control so it can be used anywhere in any room. Use a sealed bearing bottom bracket for a quiet, smooth pedaling acton. Finally: use colors and graphics that work well in the home environment. Integrate Heart Rate display by putting hand pulse sensors in a convenient spot so you can know just how hard they are working. And keep it priced far below the competition!
