There is a debate of sorts between those who prefer a rinko bag that requires removal of both wheels (ne), and those that require removal of only the front wheel (Jerome). Of course, it is a trade off between the compactness of the packed bike when on a crowded train (both-wheels-off wins) and ease and messiness of packing and unpacking (only-front-wheel-off wins). Doppelganger shows us another approach -- not marketed specifically as a rinko, but rather as a "bike cover" for storage inside a house, for example. But it will work as a rinko with both wheels on! And no straps.
I would not recommend trying a both-wheels-on style rinko except if you know you will be riding on a half (or more) empty local train. For that, it would be perfect. On or off in a minute or two.
Of course, the fabric it is very stretchable and so also could work with a strap or two as a "one wheel off" alternative.
Weight -- no more than my other lightweight ballistic nylon rinko bags, maybe less.
Cost -- at Cyclemode, it was on sale for 3000 yen, including an additional very simple "ass saver" short fender that clips onto the underside of a saddle.
