I was very curious about half-bike so i could not resist to a special sale offer last september. I've always appreciated the honest and complete way of communication of the producer, and I spent time to learn about half-bike before its delivery.
The declared learning time steps were particularly useful to me.
I've been practicing for the last five months with lot of fun , but I'm not using halbike as a mean of transport as I hoped, alternatively to bike or to walking for instance.
The difficulty of going on hilly roads is another critical aspect: although it's quite easy on plain and well-paved paths, it's not easy on sloping surfaces.
