I bought Red Halfway 7S, 7 speed last Saturday. This is my first folding bike, I have a mountain bike. Firstly before I ride the Halfway I have doubt about the stability, but when I ride it, it feels just like when I ride my mountain bike. The next plan is I want to upgrade the cassete and the crank, to have a better speed and climbing :-), and after that install a bar end or bullhorn bar :-)
