Here's a good product I assembled very easily (But I'm a walking disaster for yourself). This bike folds and unfolds and unfolds without anyone put for hours, it is relatively light and does not pose concerns for lower pedaling sessions or equal to 30/40 minutes. The seat is quite comfortable compared to many other models in the same price range. Finally, one of the strongest positives for me is probably his quiet side! I have known many bikes that woke the neighbors but it bothers no one, even if a third party is in the room with you.
Among the caveats, the level of difficulty poorly proportioned as there is almost no difference between the No. 1 and No. 8 and the obligation to give back time to time suddenly screwdriver to tighten all but overall it is a good investment as long as you do not want a competition machine.
