It’s everything I hoped it would be and feels fantastic to ride. I’ve bought it to help with a difficult commute from Odawara to Tokyo Station by Shinkansen, followed by a transfer onto the Yamanote line to Ueno - the latter two stations are two of the busiest in the world.
Using my bike has knocked 40 minutes a day off of my journey and its lightness and compact form when folded has made taking it onto the trains and through the crowded stations a viable option. It fits on the overhead luggage racks on the trains and is light enough to lift up without inconveniencing other passengers too much.
