What are the advantages of a Halfbike over a bicycle?
The two are so different that it's hard to compare them. The feeling of riding a Halfbike is frankly nothing like riding a standard bicycle. But if we must pick a few, we would probably go for the fun of riding, its lightness and compactness.
... and effect on other people ;-)
halfbike is life, halfbike is stile, halfbike is all
