I love my halfbike and I use it a lot. after having it 4 months it's still fun to ride and there's nothing like the thrill of the first few days learning to ride it! I never take my regular bicycle out anymore. because i have some back and neck problems seated bike causes some jarring that doesn't happen riding a standing bike.
I have a suggestion for the designers to please make the quick release levers longer as I am a woman and for me I cannot make them tight enough and they used to come undone while I was riding. now I never collapse it down so I don't have that problem but it's not as convenient.
