The bike is characterized first and foremost by its saddle-free design that requires the rider to step onto it and start peddling without sitting down. This immediately eliminates the occurrence of [saddle pain](https://www.trendhunter.com/trends/personomic-saddle) that can commonly occur on spin bikes, while also requiring the user to stand and cycle with more vigor. The unit thus achieves a total body workout by engaging the upper body alongside the lower body without creating any discomfort and also offering a joint-friendly high-intensity training (HIT) cycling experience.
