 Another factor in their demise was the extremely uncomfortable ride, because of the stiff wrought-iron frame and wooden wheels surrounded by tires made of iron — this led to the pejorative name "boneshaker", which is still used today to refer to this type of bicycle.Again, England was the only place where the concept remained popular during the early 1870s.But the design changed drastically, with the front wheel becoming larger and larger, and with many other improvements making the ride more comfortable.
