I'm so old I remember the first Japanese toys exported to the US after WWII. They looked just like this. But, I don't know.... inexpensive ain't bad, and I'm sure they're a lot lighter than the average bike. Still, I'll let other folks try them out first!
A comment on the user name. Several years ago, I read the John Carter stories for the first time. I enjoyed them so much that I read all of them in a short time. In some of the later stories, it did get a bit tedious with details occasionally, but overall, very good stories, and very well written.
