Hello - Lois Moss of Walk+Roll here. Interesting construction...I can see where this would be practical for transporting small loads and making deliveries. If anyone gets these going here, I'd be interested in hiring them for the Walk+Roll street-based events. You may also find a market by contracting with places that have spread out facilities...like Cleveland Clinic. Try posting on the forums for Green City Blue Lake, Entrepreneurs for Sustainability and RealNEO. Best of luck and glad to see out-of-the-box ideas in CLE!
