This bike is well designed and very compact when folded. But the quality is not at the rendezvous at the particular mechanism that lack of inertia. Hence jolts pedaling. Similarly, the resistance settings and the hardest level, it is far from what you would find on a "real" bike 300. For the electronics, the son are very thin and very fragile. The LCD counter is very small and inconvenient. Too bad because, when folded, it is really practical and aesthetic!
