This bike is exceptionally nice and solid quality for the money. It is a full 26 inch folding bike. However, the assembly instructions are only in Japanese. It comes 90% assembled and not folded in the delivery box...very nicely and securely packaged. However, you'll have to put on the seat and handle bars (making sure to insert their posts to the line inscribed on them); Then attach the front tire using the quick release toggle included in the package; Then adjust the rear brakes and front disk brakes, if necessary (my rear brakes needed no tension adjustment, though the front disc brakes needed a slight adjustment to stop the rubbing sound after turning the wheel). I searched online for instruction how to do this easily. A bell and reflectors are already attached to the bike, but they'll have to be aligned/adjusted with a screwdriver. Afterwards, it's ready to ride. Assembly time is about 20 minutes.
