If I had experience riding a skateboard or scooter as a youth, I have no doubt I could have instinctively operated my Halfbike. Halfbike requires a unique sense of balance. The autonomous sense of balance, in my case, is obviously limited to riding a bicycle dependent on a steerable front wheel. I have family members as young as 10 and as old as 40 who successfully rode my Halfbike the very first time they tried. I've tried to learn many many times, and all that happens is a crashing hard fall. This is very frustrating and disappointing. Nothing wrong with the design or manufacturing, both of which I admire greatly. I just can't ride the Halfbike.
