I am breaking the outdated "bicycle" box. We all have arms and legs, why not use both to power a conventional bicycle? I intend to build an online Dual Drive Bicycle Company one bike at a time. I would like to License my patent to fitness/bicycle companies to compete with Peloton with a better product. Please see my new improved chain drive and my first ever front wheel shaft drive invention at www.dualdrivebike.com
