I love my Zizzo folding bike!! I brought it for my house in the Pocono Mountains and love how it rides. Setting it up, folding and unfolding is soooooo easy. My only complaint is I wished it was a little lighter. Though it weights 23lbs and I can pick it up. I know itβs not built for speed, but maybe building a bike out of titanium will work. But I love it! Especially the color combination of silver/black!
