BUT: The wheel is suitable in my opinion only for people who are not clear about 1,70m tall. People like going except with strong legs bent.
I'm 1.72 and find it already borderline, but still ok. I got me a cushion placed on the saddle, and radle preferably without shoes, it's ok.
As others have mentioned, there are no really serious level can be adjusted. Here I have myself a little hurried along and turned on a few screws so that the magnets can be further put to the flywheel. Is not that hard to make. Thus, I think that's now ok. But I must say that I am not a professional cyclist, first and second, more long ride, mind also. 1 hour. By tuning I realize the cycle already clear in my legs and I'm also work up a sweat, though I've not even made it "very difficult" to (the new tuned).
Initially the device has secreted a chemical smell while pedaling, but which is now fortunately disappeared. Is probably also because I've completely removed the plastic part in Pedalbereicht, but I do not think rather that the smell came along.
So overall for little people a good deal for a good price.
