Hai Tac M. - CA
I gave up on this. As soon as you put one foot on one pedal, the halfbike tilts completely to one side. To gain the balance, you need to put both feet on both pedals at the same time but how can you you do that? So you need to have acrobat skills to ride the halfbike. I tried the Chinese version, not sure it is the same for other brands but don't think the halfbike has the stability and balance of a tricycle.
