It's a weird, small, scooter-like bicycle with an incomprehensible drive system, strange brakes, and other oddities. In terms of advantages, it looks about as light and portable as a kick-scooter, could probably tolerate a better seat and lights without too much difficulty, and is somewhat inexpensive. In disadvantages, I predict bone-shattering ride quality, inability to be used on any but a smooth paved surface, suspect build quality, discomfort, probably a low average speed, and an unfixable drive system with weird, uncustomizable ratios.
Personally it looks weird as hell but also kind of fun and ultra-portable for multi-mode transport or air travel, or backpacking.
What do the members of the BF community think? Anybody have one of these? Can the disadvantages I mentioned be cured or are they inherent?
