Spend your time exercising on your new elliptical, not assembling it! The ProForm 900 ZLE features SNAP assembly and will be ready to use in minutes from un-boxing. This is in part due to the new vertical folding mechanism which ensures you save maximum floor space when your elliptical is not in use. The 900 ZLE has a huge specification for a home cross-trainer. A 10kg flywheel with 18 levels of resistance means users of any ability can quickly dial in to their preferred intensity. iFit compatibility means it has never been easier to get your elliptical online and connect to the many great features that iFit offers.
